This discipline is known as the ``Art of Eight Limbs'' because it is characterized by the combined use of fists, elbows, knees and shins. Muay Thai became widespread internationally in the twentieth century, when practitioners from Thailand began competing in Kickboxing, mixed rules matches, as well as matches under Muay Thai rules around the world. The professional league is governed by The Professional Boxing Association of Thailand (P.A.T) sanctioned by The Sports Authority of Thailand (S.A.T.), and World Professional Muaythai Federation (WMF) overseas.
 Question: is muay thai and thai boxing the same Context: In baseball in the United States and Canada, the seventh-inning stretch is a tradition that takes place between the halves of the seventh inning of a game -- in the middle of the seventh inning. Fans generally stand up and stretch out their arms and legs and sometimes walk around. It is a popular time to get a late-game snack or an alcoholic beverage as well, as vendors end alcohol sales after the last out of the seventh inning. The stretch also serves as a short break for the players. Most ballparks in professional baseball mark this point of the game by playing the crowd sing-along song ``Take Me Out to the Ball Game''. Since the September 11 attacks, many American ballparks complement or replace the song with the playing of ``God Bless America.'' If a game goes into a fifth extra inning, a similar ``fourteenth-inning stretch'' is celebrated (as well as a possible ``twenty-first inning stretch'' or ``twenty-eighth inning stretch''). In softball games, amateur games scheduled for only seven innings, or in minor-league doubleheaders, a ``fifth-inning stretch'' may be substituted.

Despite several more years as one of the world's best players, the 2003 US Open title would remain his only Grand Slam triumph. He is the most recent North American male player to win a Grand Slam singles event, reach the top ranking, and claim the year-end world No. 1 ranking (2003). Roddick reached four other Grand Slam finals (Wimbledon in 2004, 2005 and 2009, and the US Open in 2006), losing to nemesis Roger Federer every time. Roddick was ranked in the top 10 for nine consecutive years between 2002 and 2010 at year's end and won five Masters Series titles in that period. He is married to Brooklyn Decker, a Sports Illustrated swimwear model and actress.
