​NEW YORK (AP) — Alan Porter is set to serve as the umpire crew chief and will call balls and strikes for Tuesday night’s All-Star Game at Citizens Bank Park in Philadelphia. Porter, 48, made his Major League Baseball debut in 2010, joined the league’s staff in 2013, and attained the role of crew chief in 2023. He previously served as the right-field umpire for the 2015 All-Star Game and has experience behind the plate in high-profile postseason games, having worked the World Series in 2019, 2022, and 2025.
Joining Porter on the crew are Chris Conroy at first base, Chad Whitson at second, Ryan Additon at third, Adam Beck in left field, and Edwin Moscoso in right field. Vic Carapazza will fulfill the role of video review umpire from New York, overseeing contemporary instant-replay decisions that influence on-field calls during the game.
The All-Star event brings together some of the game’s premier umpires, who are selected for their consistency, range, and ability to interpret the rules in a manner that preserves the integrity of the contest. Porter’s elevation to crew chief reflects his continued prominence within the officiating ranks and his demonstrated ability to manage games at the sport’s highest levels. His extensive major league experience has equipped him with a deep understanding of the strike zone, positioning, and communication with players and managers, all of which are essential for the high-pressure environment of an All-Star showcase.
This year’s All-Star Game in Philadelphia is expected to feature a lineup of notable players and a crowd inspired by the city’s rich baseball history. The umpires chosen for the event are responsible for enforcing the rules with consistency while maintaining a pace that keeps the game flowing, a balance that is particularly important in an exhibition setting where both teams may be including showcase-attracting performances. The crew chief’s duties include coordinating the plate-level decisions, ensuring consistent application of umpiring standards throughout the game, and managing the on-field crew to deliver a smooth, fair contest.
As part of the broader officiating team, Carapazza’s role as video review umpire underscores the league’s ongoing commitment to accuracy in judgment through modern replay technology. By reviewing close plays and calls from the central replay center, Carapazza provides an additional layer of scrutiny that complements the on-field officiating, helping to ensure that critical moments in the All-Star Game are accurately adjudicated.
Baseball’s All-Star Week remains a celebration of the sport’s best talent while offering a platform for umpires to showcase their expertise in a setting that emphasizes entertainment alongside competition. Porter’s leadership of the crew, paired with the supporting staff, aims to deliver a game that honors the tradition of the event while reflecting the precision and professionalism that characterize major league officiating. The collective effort of this umpiring team, including Conroy, Whitson, Additon, Beck, Moscoso, and Carapazza, contributes to the integrity and enjoyment of the All-Star Game for players, managers, and fans alike.
