Angels Designate Shaun Anderson for Assignment After Series of Roster Moves

The Los Angeles Angels announced a sequence of roster moves Tuesday that reshaped their pitching group and adjusted the status of multiple players coming off the injured list. The most consequential change was that right-hander Shaun Anderson was reinstated and then designated for assignment, a move that removes him from the 40-man roster and starts the club’s DFA process.

According to the Angels’ moves reported by MLB Trade Rumors, left-handers Mitch Farris and Blake Weiman were recalled from Triple-A Salt Lake. At the same time, right-hander Trevor Martin was optioned down, another sign the Angels were actively rebalancing their bullpen and spot usage as the season progresses.

The team also handled injury-related roster status. Right-hander George Klassen was sent to the 15-day injured list, retroactive to August 27, with left low back inflammation. Klassen’s retroactive placement matters for how the 15-day clock is applied, and it also indicates the Angels were trying to protect his availability while still managing the active roster footprint.

Catcher Sebastian Rivero, another player connected to the injured list, was reinstated and then optioned to Salt Lake. MLB Trade Rumors also tied Rivero to the broader set of roster adjustments that day, reflecting the Angels’ need to fit health, depth, and bullpen options into the constraints of a full 40-man roster.

After Anderson’s reinstatement, his designation for assignment capped the day’s series of transactions, and MLB Trade Rumors reported that the Angels’ 40-man roster was full after these moves. In practical terms, designating a player for assignment gives the club a short window to trade the player, release him, or place him on waivers, depending on how the roster is ultimately configured.

The moves also leave the Angels with a clearer near-term picture of who is expected to contribute immediately from the active staff. With Farris and Weiman coming back up, the club gained two left-handed options while cycling another righty (Martin) to Triple-A, a pattern commonly used to match bullpen usage with game planning.

What to watch next is how the Angels respond to Anderson’s DFA designation. If he clears waivers, Los Angeles could outright him to the minors (if eligible) or keep him in another roster status, while a claim or trade would shift the organization’s pitching depth balance again.

Beyond Anderson, the health track for Klassen is another storyline. Back inflammation is the type of issue that can affect workload and availability, so how the Angels manage his return window will likely influence bullpen flexibility in the final stretch of the season.
