Charlie Reliford

On September 3, 2008, Reliford was the crew chief for the first major league game in history to use instant replay on a boundary home run call. Alex Rodriguez of the New York Yankees had hit a ball near the left field foul pole at Tropicana Field that was ruled a home run by third-base umpire Brian Runge. Although all the umpires agreed with the call, Tampa Bay Rays manager Joe Maddon argued the ball was foul and asked for a review; however, by rule, the decision to review was solely Reliford's to make as the crew chief. After a conversation with the other umpires, Reliford agreed to the replay and after a brief review upheld the initial home run call.

Reliford officiated in the World Series in 2000 and 2004, and in the All-Star Game in 1996 and 2007. He has also umpired in three League Championship Series (1999, 2001, 2002) and in four Division Series (1995, 1997, 2000, 2004).

In Game 2 of the 2000 World Series, Reliford was the home plate umpire when Mike Piazza of the New York Mets had his bat shatter and fly towards the pitcher's mound on a foul ball. Roger Clemens of the New York Yankees fired the sawed-off piece of the bat toward Piazza, causing both benches to empty and reigniting the controversy that had begun the previous July, when Clemens had hit Piazza in the head with a pitch during an interleague game at Yankee Stadium.

Reliford began umpiring in the minor leagues in 1982, eventually reaching the Triple-A American Association. He made his NL debut on May 29, 1989.
