In modern day baseball, teams generally have five starting pitchers, and they take it in turn to start a game every fifth day (hence the phrase rotation). Sometimes, if the schedule pans out, a team can get away with a four man rotation, and in the distant past some teams managed a three man rotation.
A pitcher who prevents the opposing team from achieving a hit is said to have thrown a no-hitter. This is a rare accomplishment for a pitcher or pitching staff: only 295 have been thrown in Major League Baseball history since 1876, an average of about two per year. In most cases in MLB, no-hitters are recorded by a single pitcher who throws a complete game; one thrown by two or more pitchers is a combined no-hitter.
