Diagram of a baseball field . The starting point for much of the action on the field is home plate ( officially `` home base '' ) , which is a five - sided slab of whitened rubber , 17 inches ( 43 cm ) square with two of the corners removed so that one edge is 17 inches long , two adjacent sides are 8.5 inches ( 22 cm ) and the remaining two sides are 12 inches ( 30 cm ) and set at an angle to make a point . The plate is set into the ground such that its surface is level with the surrounding ground . Adjacent to each of the two parallel 8.5 - inch sides is a batter 's box . The point of home plate where the two 12 - inch sides meet at right angles is at one corner of a 90 - foot ( 27.43 m ) square . The other three corners of the square , in counterclockwise order from home plate , are called first , second , and third base . Three canvas or rubber bases 15 inches ( 38 cm ) square and 3 -- 5 inches ( 7.6 -- 12.7 cm ) in thickness made of soft material mark the three bases . Near the center of the square is an artificial hill known as the pitcher 's mound , atop which is a white rubber slab known as the pitcher 's plate , colloquially the `` rubber . '' The specifications for the pitcher 's mound are described below . All the bases , including home plate , lie entirely within fair territory . Thus , any batted ball that touches those bases must necessarily be in fair territory . While the first and third base bags are placed so that they lie inside the 90 - foot square formed by the bases , the second base bag is placed so that its center ( unlike first , third and home ) coincides exactly with the `` point '' of the ninety - foot square . Thus , although the `` points '' of the bases are 90 feet apart , the physical distance between each successive pair of base markers is closer to 88 feet ( 26.8 m ) . The lines from home plate to first and third bases extend to the nearest fence , stand or other obstruction and are called the foul lines . The portion of the playing field between ( and including ) the foul lines is fair territory ; the rest is `` foul territory . '' The area within the square formed by the bases is officially called the infield , though colloquially this term also includes fair territory in the vicinity of the square ; fair territory outside the infield is known as the outfield . Most baseball fields are enclosed with a fence that marks the outer edge of the outfield . The fence is usually set at a distance ranging from 300 to 420 feet ( 90 to 130 m ) from home plate . Most professional and college baseball fields have a right and left foul pole . These poles are at the intersection of the foul lines and the respective ends of the outfield fence and , unless otherwise specified within the ground rules , lie in fair territory . Thus , a batted ball that passes over the outfield wall in flight and touches the foul pole is a fair ball and the batter is awarded a home run . First base ( edit ) Main article : First baseman Left field foul pole at Citi Field in Flushing , Queens . First base is the first of four bases that must be touched by a player on the batting team in order to score a run . Unlike when an offensive player reaches second or third base , it is permissible for a batter - runner to overrun first base without being in jeopardy of being put out . After contact is made with the base , the batter - runner may slow down and return to first base at his leisure , so long as he makes no move or attempt to advance to second base . The first baseman is the defensive player responsible for the area near first base . A professional first baseman is often a slow runner and tall . A tall first baseman presents a large target to which other fielders can throw , and his height gives him a larger range in reaching and catching errant throws . Players who are left - handed are marginally preferable for first base because : first , it is easier for a left - handed fielder to catch a pick - off throw from the pitcher and tag the baserunner ; and , second , it is easier for a left handed thrower to make the throw to second base to start a 3 -- 6 -- 3 , 3 -- 6 -- 4 , or a 3 -- 6 -- 1 double play . Also , a right - handed first baseman must , when setting himself up to receive a throw from an infielder , execute a half - pivot near the base ; this is a move that a left - hander need not make ( this advantage is very marginal , however ) . There are three infield positions that can only effectively be occupied by right - handed players : 2nd base , 3rd base , and shortstop . This is because of the time it takes to pivot and set to throw . It takes a left - handed thrower more time to make that pivot and in the fast - paced major league game , that time is critical . As a result , there are fewer positions a left - handed player can occupy , and if that player is not fast , the outfield may not be a good fit . In the numbering system used to record defensive plays , the first baseman is assigned the number 3 . Second base ( edit ) Main article : Second baseman Second base is the second of four stations on a baseball diamond which must be touched in succession by a base runner in order to score a run for that player 's team . Second base is typically defended by the second baseman and the shortstop . Second base is also known as the keystone sack . A runner on second base is said to be in `` scoring position , '' owing to the high likelihood of reaching home plate and scoring a run from second base on most base hits . Since second is the farthest base from home plate , it is the most common target of base stealing . Ideally , the second baseman and shortstop possess quick hands and feet and the ability to release the ball rapidly and with accuracy . One will usually cover second base when the other attempts to field the ball . Both players must communicate well to be able to make a double play . Particular agility is required of the second baseman in double play situations , which usually forces the player to throw towards first while his momentum carries him in the opposite direction . In the numbering system used to record defensive plays , the second baseman is assigned the number 4 , and the shortstop 6 . Third base ( edit ) Andy Wilkins rounds third base following a home run for the 2010 Arkansas Razorbacks baseball team . Main article : Third baseman Third base is the third of four bases a base runner must touch in a counterclockwise succession in order to score a run . Many batted balls that result in the batter being put out ( such as a sacrifice fly ) may nevertheless allow a runner to reach home plate and score a run from third base , provided that the third and final out is not recorded before he can do so . A runner on third base is therefore particularly valuable to the batting team when fewer than two outs have been recorded . The third baseman is the defensive player whose responsibility is to defend the area nearest to third base . A third baseman ideally possesses quick reaction to batted balls and a strong arm to make the long throw to first base . The distance from 3rd to 1st is about 127 feet ( 39 m ) . In the numbering system used to record defensive plays , the third baseman is assigned the number 5 . Home plate ( edit ) `` Home plate '' redirects here . For other uses , see Home plate ( disambiguation ) . Home plate of a baseball field Home plate , formally designated home base in the rules , is the final base that a player must touch to score . Unlike the other bases , home plate is a five - sided slab of whitened rubber that is set at ground level . The use of rubber was developed by Robert Keating , who pitched one game for the 1887 Baltimore Orioles . Previously -- and more dangerously -- the plate was made of stone , iron , or wood . The dimensions of home plate are 17 inches ( 43 cm ) across the front , 8.5 inches ( 22 cm ) down each side , with a triangular rear of two sides of 12 inches ( 30 cm ) . The rear edges are at 45 degrees to the sides , making a point at the back . The plate is white and surrounded by a black strip ⁄ inch ( 1.9 cm ) in width . The plate sits entirely in `` fair '' territory , with the two rear edges aligned with the right and left field foul lines . The length and angle requirements for home plate mandate that it is not a regular pentagon ; it is a 17 by 8.5 inches rectangle with an isosceles triangle of base 17 inches and equal sides of 12 inches attached to the back . 50 to 100 feet ( 15 to 30 meters ) behind home plate is the backstop , which is a wall / fence that will stop wild pitches , passed balls , and foul balls . In enclosed stadiums , the backstop is often composed of a lower part , which is like any other part of the wall , and an upper netting to protect spectators seated behind it ; in recreational baseball fields , there is usually a tall chain - link fence , including an angled top section , composing the entire backstop . Batter 's box and catcher 's box ( edit ) David Ortiz ( in gray ) of the Boston Red Sox stands in the left - handed hitters ' batter 's box at U.S. Cellular Field against the Chicago White Sox on July 7 , 2006 . The batter 's box is the place where the batter stands when ready to receive a pitch from the pitcher . It is usually drawn in chalk on the dirt surrounding home plate , and the insides of the boxes are watered down before each game . The chalk lines delineating the two foul lines are rarely extended through the batter 's boxes . However , those lines exist conceptually for the purpose of judging a batted ball fair or foul . In addition , inside edges of the batter 's boxes are often not laid - in with chalk . Similarly , though not marked , those lines continue to exist for the purpose of the rules pertaining to the batter 's box and the batter 's position relative thereto . There are two batter 's boxes , one on each side of home plate . The batter 's boxes are 4 feet ( 1.22 m ) wide and 6 feet ( 1.83 m ) long . The batter 's boxes are centered lengthwise at the center of home plate with the inside line of each batter 's box 6 inches ( 15 cm ) from the near edge of home plate . A right - handed batter would stand in the batter 's box on the left side of home plate from the perspective of the catcher and umpire . A left - handed batter would stand in the batter 's box to their right . A batter may only occupy one batter 's box at a time and may not legally leave the batter 's box after the pitcher has come set or has started his windup . Should the batter wish to leave the batter 's box once the pitcher has engaged the rubber , he must first ask the umpire for time - out . Time will not be granted if the pitcher has already started his pitching motion . For playing rules relating to the batter 's box , see Rules 6.05 and 6.06 of the Official Baseball Rules . Foul poles ( edit ) One of two foul poles at Citizens Bank Park , Philadelphia . Foul poles , if present , help umpires judge whether a fly ball hit above the fence line is foul ( out of play ) or fair ( a home run ) . The poles are a vertical extension of the foul lines at the edge of the field of play . The outer edge of the foul lines and foul poles define foul territory . Both the lines and the poles are in fair territory , in contrast to American football and basketball , where the lines marking the playing boundaries are out of bounds . The minimum distance to hit a home run ( along either foul line ) is set by baseball rules , generally at 325 feet ( 99 m ) . Before 1920 , the foul lines extended indefinitely ; a batter was awarded a home run only if a fly ball out of the field was fair where it landed , or `` when last seen '' by the umpire . Now , a batted ball that leaves the field in flight is judged fair or foul at the point it leaves the field . Thus , such a fly ball passing on the fair side of a foul pole , or hitting a foul pole , is a home run regardless of where the ball goes thereafter . Foul poles are typically much higher than the top of the outfield fence or wall , and often have a narrow screen running along the fair side of the pole . This further aids the umpires ' judgment , as a ball that bounces off this screen is a home run . It can still be a difficult call , especially in ballparks with no outfield stands behind the poles to provide perspective . Wrigley Field is notorious for arguments over long , curving flies down a foul line ( most notably in left field ) that sail higher than the foul pole . At Major League Baseball fields , foul poles are usually yellow . Those at Citi Field are orange . At the Rogers Centre , there are no foul poles , but large nets suspended from the roof that serve the same purpose . At Petco Park , there is no foul pole in left field ; the pole 's function is served by a yellow metal strip along the corner of the Western Metal Supply Co. building . Pitcher 's mound ( edit ) The pitcher moves forward off the rubber as the pitch is released . In roughly the middle of the square , equidistant between first and third base , and a few feet closer to home plate than to second base , is a low artificial hill called the pitcher 's mound . This is where the pitcher stands when throwing the pitch . Atop the mound is a white rubber slab , called the pitcher 's plate or pitcher 's rubber . It measures 6 inches ( 15 cm ) front - to - back and 2 feet ( 61 cm ) across , the front of which is exactly 60 feet 6 inches ( 18.44 m ) from the rear point of home plate . This peculiar distance was set by the rule makers in 1893 , not due to a clerical or surveying error as popular myth has it , but intentionally ( further details under History ) . In Major League Baseball , a regulation mound is 18 feet ( 5.5 m ) in diameter , with the center 59 feet ( 18 m ) from the rear point of home plate , on the line between home plate and second base . The front edge of the pitcher 's plate or rubber is 18 inches ( 46 cm ) behind the center of the mound , making the front edge 's midpoint 60 feet 6 inches from the rear point of home plate . Six inches ( 15 cm ) in front of the pitcher 's rubber the mound begins to slope downward . The top of the rubber is to be no higher than ten inches ( 25 cm ) above home plate . From 1903 through 1968 , this height limit was set at 15 inches ( 38 cm ) , but was often slightly higher , sometimes as high as 20 inches ( 51 cm ) , especially for teams that emphasized pitching , such as the Los Angeles Dodgers , who were reputed to have the highest mound in the majors . A pitcher will push off the rubber with his foot in order to gain velocity toward home plate when pitching . In addition , a higher mound generally favors the pitcher . With the height advantage , the pitcher gains more leverage and can put more downward velocity on the ball , making it more difficult for the batter to strike the ball squarely with the bat . The lowering of the mound in 1969 was intended to `` increase the batting '' once again , as pitching had become increasingly dominant , reaching its peak the prior year ; 1968 is known among baseball historians as `` The Year of the Pitcher . '' This restrictive rule apparently did its job , contributing to the hitting surge of modern baseball . A pitcher 's mound is difficult for groundskeepers to maintain . Usually before every game it is watered down to keep the dust from spreading . On youth and amateur baseball fields , the mound may be much different from the rule book definition due to erosion and repair attempts . Even in the major leagues , each mound gains its own character , as pitchers are allowed to kick away pieces of dirt in their way , thereby sculpting the mound a bit to their preference . The pitcher may keep a rosin bag on the rear of the mound to dry off his hands . Major League Baseball teams are also permitted cleat cleaners on the back of the mound . This may be a flat grate - style plate , or simply a hand tool such as a piece of wood used to remove mud and dirt from cleats . These items are allowed to remain on the backside of the mound at the discretion of the umpire , thus reducing the probability that they will affect a live play . Baseline ( edit ) A baseline is the straight line between two adjacent bases . Baselines are not drawn on the field , although the foul lines serve to mark the baseline between home plate and first base , and between third base and home . Running baseline ( edit ) Generally , base runners are not required to follow the baseline . A base runner seeking to advance more than one base typically `` rounds '' the base , following a more circular path . However , a base runner 's left - right motion is constrained when the defense tries to tag him . At the moment the defense begins the attempt , the baserunner 's running baseline is established as a direct line from his current position to the base he is trying for . A runner straying more than three feet ( 1 m ) away from this baseline to avoid a tag may be called out . Running lane ( edit ) Beginning halfway between home and first base , and ending at first base , there is a second chalk line to the right of the foul line . This second line and the part of the foul line it runs parallel to , form the running lane that defines the path in which a batter - runner must run as he is advancing to first base . Rule 6.05 ( k ) of the Official Baseball Rules states that , if a batter - runner running to first base runs outside the running lane , and `` in doing so '' interferes with the fielder taking the throw at first , then the batter - runner is automatically out . First base itself is not located in the running lane , but Rule 6.05 lets the batter - runner leave the running lane `` by means of a step , stride or slide in the immediate vicinity of first base '' to step on first base . Grass line ( edit ) The H.H.H. Metrodome , showing a white `` grass '' line . The grass line , where the dirt of the infield ends and the grass of the outfield begins , has no special significance to the rules of the game , but it can influence the outcome of a game . Dirt running paths between the bases ( and , at one time and still in some parks , between the pitcher and the catcher ) have existed since the beginning of the game , although they were not mentioned in the rule books until around 1950 , and their specifications are flexible . In addition to providing a running path , the grass lines act as a visual aid so that players , umpires and fans may better judge distance from the center of the diamond . Occasionally the ball may take a tricky bounce off the dirt area or the edge between the dirt and the grass . Multiple World Series championships ( including 1924 , 1960 and 1986 ) have been decided or heavily influenced by erratic hops of ground balls . In artificial turf stadiums , infield dirt was originally only placed around the bases and around the pitcher 's and batting areas , which are referred to as `` sliding pits . '' In this configuration , the `` grass line '' is usually designated with a white arc . Among Major League Baseball fields , Rogers Centre was the last stadium to maintain this type of configuration and was reconfigured with a full dirt infield starting in the 2016 MLB season . In some college baseball parks with artificial turf fields , the entire field ( along with possibly the pitcher 's mound ) is made up of turf , with parts of the field mainly containing dirt instead merely being clay - colored turf . Outfield ( edit ) The outfield is made from thick grass or artificial turf . It is where the outfielders play . The positions to play in the outfield are right , center , and left field ( named in relation to the batter 's position ; thus left field is beyond third base and right field is beyond first base ) . Outfields vary in size and shape depending on the overall size and shape of the playing field . The outfield stretches from the infield to the outfield wall and it contains the warning track . Outfields especially vary from Little League to Major League fields . Little League outfields vary more in size than Major League outfields . Outfields often differ from infields in the specific type of grass used , but most Major League outfields are grass . Warning track ( edit ) The bottom of the picture shows part of the orange - colored clay warning track at Fenway Park . The warning track is the strip of dirt at the edges of the baseball field ( especially in front of the home run fence and along the left and right sides of a field ) . Because the warning track 's color and feel differ from the grass field , a fielder can remain focused on a fly ball near the fence and measure his proximity to the fence while attempting to catch the ball safely . A warning track 's width is not specified in the rules . It is generally designed to give about three steps of warning to the highest - level players using the field . Typical widths run from about six feet for Little League fields to about 10 -- 15 feet ( 3.0 -- 4.6 meters ) for college - or professional - level play . A warning track this wide also lets groundskeepers avoid driving maintenance vehicles on the grass . The track can be composed of finely ground rock particles such as cinders , which is why announcer Bob Wolff called it the `` cinder path '' rather than the `` warning track . '' The idea of a warning track originated in Yankee Stadium , where an actual running track was built for use in track and field events . When ballpark designers saw how the track helped fielders , it soon became a feature of every ballpark . Single - minded fielders often crash into a wall trying to make a catch despite the warning track . For this reason , outfield walls are typically padded for extra safety . Wrigley Field 's brick wall is covered only by ivy , which is not especially soft . However , there are pads on the walls of the tight left and right field corners in foul ground . Warning - track power is a derogatory term for a batter who seems to have just enough power to hit the ball to the warning track for an out , but not enough to hit a home run . The term more generally refers to someone or something that is almost but not quite good enough for something . Outfield wall ( edit ) The Green Monster in 2006 , showing the manual scoreboard and Green Monster seating , and more recent additions , including charity advertisements along the top , billboards above the Green Monster seating , and the American League East standings . Pitchers warming up in the bullpen The outfield wall or outfield fence is the wall or fence that marks the outer boundary of the outfield . A ball passing over the wall is dead ; if it passes over the wall in fair territory while in flight , it is a home run . The official rules do not specify the shape , height , or composition of the wall , or a specific mandatory distance from home plate ( though Major League Baseball mandates a minimum distance of 250 feet ( 76 m ) and recommends a minimum distance of 320 feet ( 98 m ) at the foul poles and 400 feet ( 120 m ) at center field ) . As a result , baseball fields can vary greatly along those lines . The wall has numbers affixed or painted on it that denote the distance from that point on the wall to home plate . In most modern major league ballparks , the wall is made of some hard material ( e.g. , concrete , plywood , sheet metal ) with padding on the field side to protect players who may collide with the wall at high speed while trying to make a play . Chain link fencing may also be incorporated into the wall in areas where the wall needs to be transparent , e.g. , an outfield bullpen , a spectator area behind the wall , or to protect a scoreboard incorporated into the wall . Many ballparks feature a yellow line denoting the top of the wall to aid umpires in judging whether the ball passed over the wall or if the ball is fair or foul . Bullpen ( edit ) Main article : Bullpen The bullpen ( sometimes referred to as simply `` the ' pen '' ) is the area where pitchers warm up before entering a game . Depending on the ballpark , it may be situated in foul territory along the baselines or just beyond the outfield fence . Relief pitchers usually wait in the bullpen when they have yet to play in a game , rather than in the dugout with the rest of the team . The starting pitcher also makes his final pregame warmups in the bullpen . Managers can call coaches in the bullpen on an in - house telephone from the dugout to tell a certain pitcher to begin his warmup tosses . `` Bullpen '' is also used metonymically to describe a team 's collection of relief pitchers . On - deck circles ( edit ) Main article : On - deck There are two on - deck circles in the field , one for each team , positioned in foul ground between home plate and the respective teams ' benches . They are technically known as next - batter 's boxes . The on - deck circle is where the next scheduled batter , or `` on - deck '' batter , warms up while waiting for the current batter to finish his turn . The on - deck circle is either an area composed of bare dirt ; a plain circle painted onto artificial turf ; or often , especially at the professional level , a mat made from artificial material , with the team or league logo painted onto it . Coach 's boxes ( edit ) The coach 's boxes , located behind first and third base , are where the first and third base coaches are supposed to stand , although coaches often stand outside the box . This is permissible as long as the coach does not interfere with play and the opposing team does not object ( in which case the umpire shall ensure that all coaches on both teams must abide by the boundaries of the coach 's boxes ) . The coach 's boxes are marked with chalk or paint . In the early days of baseball , the term `` coacher 's box '' was used , as `` coach '' was taken to be a verb . As the term `` coach '' evolved into a noun , the name of the box also changed . History ( edit ) This section possibly contains original research . Please improve it by verifying the claims made and adding inline citations . Statements consisting only of original research should be removed . ( May 2012 ) ( Learn how and when to remove this template message ) The basic layout of the diamond has been little changed since the original Knickerbocker Rules of the 1840s . The distance between bases was already established as 90 feet ( 27.43 m ) , which it remains to this day . Through trial and error , 90 feet had been settled upon as the optimal distance . 100 feet would have given too much advantage to the defense , and 80 feet too much to the offense . The original Knickerbocker Rules did not specify the pitching distance explicitly . By the time major league baseball began in the 1870s , the pitcher was compelled to pitch from within a `` box '' whose front edge was 45 feet ( 14 m ) from the `` point '' of home plate . Although he had to release the ball before crossing the line , as with bowlers in cricket , he also had to start his delivery from within the box ; he could not run in from the field as bowlers do . Furthermore , the pitcher had to throw underhand . By the 1880s , pitchers had mastered the underhand delivery -- in fact , in 1880 , there were two perfect games within a week of each other . In an attempt to `` increase the batting , '' the front edge of the pitcher 's box was moved back 5 feet in 1881 , to 50 feet ( 15 m ) from home plate . The size of the box was altered over the following few years . Pitchers were allowed to throw overhand starting in 1884 , and that tilted the balance of power again . In 1887 , the box was set at 4 feet ( 1.2 m ) wide and 5.5 feet ( 1.7 m ) deep , with the front edge still 50 feet from the plate . However , the pitcher was compelled to deliver the ball with his back foot at the 55.5 - foot ( 16.9 m ) line of the box , thus somewhat restricting his ability to `` power '' the ball with his overhand delivery . In 1893 , the box was replaced by the pitcher 's plate , although `` the box '' is still used today as a slang term for the pitcher 's location on the field . Exactly 5 feet was added to the point the pitcher had to toe , again `` to increase the batting '' ( and hopefully to increase attendance , as fan interest had flagged somewhat ) , resulting in the seemingly peculiar pitching distance of 60.5 feet ( 18.44 m ) . Many sources suggest that the pitching distance evolved from 45 to 50 to 60.5 feet . However , the first two were the `` release point '' and the third is the `` pushoff point , '' so the 1893 increase was not quite as dramatic as is often implied ; that is , the 1893 rule change added only 5 feet to the release point , not 10.5 feet . Originally the pitcher threw from flat ground , but over time the raised mound was developed , somewhat returning the advantage to the pitchers . Before the mid-20th century , it was common for baseball fields to include a dirt pathway between the pitcher 's mound and home plate . This feature is sometimes known as the `` keyhole '' due to the shape that it makes together with the mound . The keyhole was once as wide as the pitcher 's box and resembled a cricket pitch . Sometimes this path extended through the batting area and all the way to the backstop . Once the rounded pitcher 's mound was developed , the path became more ornamental than practical , and was gradually thinned before being largely abandoned by the 1950s . In recent years some ballparks , such as Comerica Park and Chase Field in the major leagues , have revived the feature for nostalgic reasons .
