LAS VEGAS — The A's have named Cam Castro the organization’s new General Manager. Castro joins the A’s after having just won the 2026 World Series as the Senior Vice President of Player Development and Performance with the Milwaukee Brewers.

Castro spent eight seasons in Milwaukee and was responsible for the skill development strategies used by the Brewers to train and develop minor league players. He also oversaw the team’s high performance systems, including medical operations, and served as a player-development bridge from the front office to the Major League coaching staff.

“I'm beyond thankful to John Fisher, Taylor Smith, Ross Bowen and the entire Athletics organization for this opportunity,” Castro said. “The A's are a historic franchise with an incredible legacy. I look forward to being a part of the next chapter of A's baseball and developing a team, culture, and organization that our fans will be proud of.”

“Cam will be an awesome addition to the front office and a great partner to me in running this organization,” said A’s president of baseball operations Taylor Smith. “He has experiences and skillsets that will complement me and the very talented people that we already have in the organization. He's one of the best development minds in the game with a proven track record of building the systems and processes that develop a winner.”

Castro, 36, joined the Brewers in 2019 as their Single-A pitching coach after spending seven seasons coaching at the collegiate level with Defiance College and Lake Erie College. With the Brewers, he also held the roles of minor league pitching coordinator, director of pitching development, and vice president of player development. Castro graduated from Lake Erie College with a bachelor’s degree in legal studies and from Defiance College with a master’s degree in sports management and worked as a trainer at Driveline Baseball.
