A's Name Cam Castro GM After Major Front Office Shakeup

The Athletics have named Cam Castro as their new general manager, filling a role that had been vacant since the team mutually parted ways with David Forst.

Castro joins the organization after spending seven seasons with the Milwaukee Brewers, where he worked in baseball operations and pitching development.

He was part of the Brewers' front office when the franchise won its first World Series championship.

Taylor Smith, whom the A's hired from the Boston Red Sox to serve as President of Baseball Operations, brought Castro in.

Smith and Castro will now work together to reshape a roster that finished the 2026 season with clear strengths and one glaring weakness.

The A's offense ranked among the best in baseball last season.

Their pitching staff, however, was young and inexperienced — and it cost them any realistic chance at a postseason run.

Castro's background is in pitching development.

He joined the Brewers' organization in 2019 after working as a Division II baseball coach.

In Milwaukee, he helped build a system that developed and acquired arms capable of winning at the highest level.

Now he will try to replicate that success in West Sacramento, where the A's are playing in a minor league ballpark while their permanent stadium situation remains unresolved.

The ballpark factor makes free agent pitching harder to attract.

Castro will need to use his experience to find underrated talent and get the most out of them.

The A's already have several young pitchers on the roster or in the pipeline.

JT Ginn, Gage Jump, Jacob Lopez and Jamie Arnold are all arms the organization is counting on.

Adding experienced veterans could help those younger pitchers develop faster.

The offseason trade market is expected to include plenty of teams looking to move pitching.

There are also numerous arms available in free agency.

Castro and Smith will have to decide which route gives the A's the best chance to compete in 2027.

The A's have been without a general manager for several months.

Forst's departure left a gap that the front office needed to fill before the offseason's critical decisions.

Castro's arrival gives the organization a clear leadership structure heading into the winter.

Smith will oversee baseball operations at the highest level.

Castro will manage the day-to-day work of building the roster, with a specific focus on pitching.

The two executives have complementary backgrounds.

Smith spent years with the Red Sox, one of baseball's most resource-rich organizations.

Castro comes from the Brewers, a franchise known for maximizing limited resources through smart development and creative acquisitions.

The A's are hoping that combination produces results.

Castro's first major test will come this offseason.

The pitching staff needs multiple additions, both in the rotation and the bullpen.

Some of those additions could come from his former organization.

Castro knows the Brewers' system and its players better than almost anyone outside Milwaukee.

It would not be surprising if he targets former Brewers who fit the A's budget and timeline.

The A's also brought in Nate Eaton from the Red Sox earlier this offseason.

Sonny Gray has been mentioned as a potential target, given Smith's history with the veteran pitcher in Boston.

Castro will evaluate all options before making any moves.

The A's front office has undergone significant change in recent months.

Smith's arrival from Boston signaled a new direction.

Castro's hiring confirms that the organization is serious about building a winner.

The question now is whether they can execute the plan.

Pitching is the hardest commodity to find in baseball.
