Bruce Neal Froemming is 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.
