Jim Joyce has joined John Hirschbeck, Tim Welke and Bob Davidson in retiring from Major League Baseball's umpire staff. The commissioner's office said Tuesday that Adam Hamari, Pat Hoberg, Gabe Morales and Carlos Torres have been promoted to the full-time staff. Hirschbeck, the crew chief in last year's World Series and a big league umpire since 1984, had announced his planned retirement last year, as did Welke and Davidson.
