Mark David McGwire, nicknamed "Big Mac", is an American former professional baseball first baseman who played 16 seasons in Major League Baseball (MLB) from 1986 to 2001 for the Oakland Athletics and the St. Louis Cardinals. He won two World Series championships, one with Oakland as a player in 1989 and one with St. Louis as a coach in 2011. One of the most prolific home run hitters in baseball history, McGwire hit 583 home runs during his career, which ranked 5th-most in MLB history at the time of his retirement and currently ranks 11th. He holds the major-league career record for at bats per home run ratio (10.6), and is the former record holder for both home runs in a single season and home runs hit by a rookie. McGwire was one of several central figures in baseball's steroids scandal.
In baseball, the umpire is the person charged with officiating the game, including beginning and ending the game, enforcing the rules of the game and the grounds, making judgment calls on plays, and handling disciplinary actions. The term is often shortened to the colloquial form ump. They are also sometimes nicknames as blue due to the tradtional color of the uniform worn by umpires. Although games were often officiated by a sole umpire in the formative years of the sport, since the turn of the 20th century, officiating has been commonly divided among several umpires, who form the umpiring crew. The position is analogous to that of a referee in many other sports.
In baseball, a pitcher may commit illegal motions or actions that constitute a balk. Most of these violations involve pitchers pretending to pitch when they have no intention of doing so. In games played under the Official Baseball Rules that govern professional play in the United States and Canada, a balk results in a dead ball or delayed dead ball. In certain other circumstances, a balk may be wholly or partially disregarded. In the United States, under the National Federation of State High School Associations, a balk results in an immediate dead ball. In the event a balk is enforced, the pitch is generally nullified, each runner is awarded one base, and the batter (generally) remains at bat with the previous count. The balk rule in Major League Baseball was introduced in 1898.
Bruce Neal Froemming is an American Major League Baseball Special Assistant to the Vice President on Umpiring, after having served as an umpire in Major League Baseball. He first umpired in the National League in 1971, and from 2000 to 2007 worked throughout both major leagues. Early in the 2007 season, Froemming tied Bill Klem for the most seasons umpired. Previously, on August 16, 2006, Froemming umpired his 5,000th game between the Detroit Tigers and Boston Red Sox at Fenway Park, making him the second umpire to reach that milestone; Klem retired after 5,374 games. Froemming now stands third on the all-time list of games umpired, having been passed when Joe West officiated his 5,164th Major League Baseball game on August 14, 2019. On April 20, 2007, he umpired at first base in the Cleveland Indians-Tampa Bay Devil Rays game, passing Klem to become – at age 67 years 204 days – the man then believed to be the oldest umpire in major league history; Hank O'Day holds the record, retiring at 68 years, 2 months. He worked his final regular-season game at age 68 years 2 days on September 30, 2007, when Froemming received a standing ovation before umpiring his last regular-season game, manning the third base position as the Milwaukee Brewers hosted the San Diego Padres at Miller Park in his native Milwaukee, with much of his family in attendance. Because Froemming was then over age 65, he became eligible for election to the Baseball Hall of Fame in 2010 instead of having to wait the customary five years.

Major League Baseball (MLB) uses instant replay review to allow league officials to review certain types of plays in order to determine the accuracy of the initial call of the umpires on the field. Reviews may be initiated either by a team's manager with limitations or by the umpires themselves. All instant replay reviews are examined by umpires at the Replay Command Center in New York City, who have the final decision as to whether to uphold or overturn the initial call.
