A’s Hire Brewers Pitching Architect Cam Castro As General Manager

The move signals a focused rebuild of the club’s pitching development as the new front office prepares offseason plans and the franchise’s planned 2028 move to Las Vegas.

Overview

  • The Athletics named Cam Castro their general manager, with the team announcing the hire on Wednesday and saying he will report to president of baseball operations Taylor Smith.
  • Castro, 36, arrives from the World Series champion Milwaukee Brewers where he rose from minor-league pitching coach to senior vice president of player development and performance.
  • The A’s gave Castro a clear mandate to fix their pitching development pipeline after a 2026 season in which the team posted one of baseball’s worst ERAs and WHIP numbers.
  • Castro said he plans to adopt Brewers-style development practices such as faster feedback loops and integrated coaching, medical, strength and analytics work across the major- and minor-league systems.
  • The hire ties to the club’s longer-term plan to move to a new Las Vegas ballpark in 2028 and could help recruit staff and players, but immediate offseason work will be paced by staffing decisions and broader MLB labor and calendar constraints.
