Laz Diaz, a veteran Major League Baseball umpire with a 31-year career, announced his retirement following the conclusion of the 2024 regular season. Diaz, who made his major league debut in 1995 at Detroit’s Tiger Stadium, will conclude his umpiring tenure at Comerica Park in Detroit, where he is scheduled to be the home-plate umpire for pitcher Justin Verlander’s final appearance on September 26. Verlander is a future Hall of Famer, and Diaz notably was behind the plate for Verlander’s first postseason game in 2006 at Yankee Stadium.
Diaz’s career spanned significant changes in the sport’s officiating. When he began, the role of an umpire was markedly different, absent many of today’s technological aids such as video reviews, automated strike zones, pitch communication devices, and centralized replay review centers in New York. Additionally, protocols like mandatory banned substance testing and the public ranking of umpires were not yet in place.
Describing umpiring as one of the most demanding and least appreciated roles in baseball, Diaz spoke candidly about the pressures faced by officials in the modern game. He emphasized the intense scrutiny and criticism umpires endure, often amplified by social media and public discourse, citing examples such as the controversies surrounding umpires Angel Hernandez and C.B. Bucknor. Diaz conveyed the emotional toll of constant negative feedback despite the professionalism umpires maintain.
Reflecting on the evolution of umpiring, Diaz expressed a fondness for the camaraderie and friendships formed throughout his career but lamented the increasing technical restrictions that limit the traditional ways umpires managed the game on the field. He also shared lighter moments, including occasional unintended use of a live microphone that inadvertently broadcast obscenities to stadium crowds.
Diaz’s pathway to the major leagues included playing minor league baseball as an outfielder and shortstop before joining MLB’s full-time umpiring staff in 1999. His career highlights include officiating in three World Series, presiding over Barry Bonds’ 756th home run game, Mark Buehrle’s perfect game, multiple World Baseball Classic games held in Japan and Puerto Rico, and the inaugural Field of Dreams Game in Iowa. He has preserved memorabilia from key moments, including the lineup cards from his first and final World Series games.
Looking ahead, Diaz plans to retire to Orlando, Florida, with intentions to spend time fishing in Puerto Rico. He also expressed interest in working as a deckhand on chartered boat tours. Reflecting on his career, Diaz said, “I’ve been blessed. The Lord has definitely blessed me throughout my career. It was a great run. But now, it’s time.”
