Angels add left-hander Sammy Peralta to the active mix by selecting his contract

On August 10, the Los Angeles Angels announced they selected the contract of left-hander Sammy Peralta, a move that brings the pitcher onto their active roster picture as the team opened a couple of 40-man roster vacancies. The transaction indicates the Angels’ intent to add bullpen depth, using the final weeks of the season to stay flexible as games pile up and late-inning matchups tighten.

The corresponding roster bookkeeping included clearing space by placing right-hander Shaun Anderson on the 15-day injured list with right shoulder inflammation. That designation, per the team’s reported transaction context, creates the required room for Peralta’s promotion and reflects the team’s medical caution with a pitcher who relies heavily on shoulder health.

Peralta’s selection matters most for how it changes usage options. In the final stretch, managers often lean on left-right bullpen balance, matchup-specific leverage, and the ability to spot-start bullpen arms between higher-leverage innings. Adding a left-hander can be particularly valuable in a lineup ecosystem that frequently turns on platoons, especially against teams with heavy left-handed power.

For the Angels, the move also fits the reality of roster construction in August. When 40-man vacancies appear, teams can either keep players in reserve roles or promote them in a way that gives the club more doors to walk through tactically. The reported announcement indicates Los Angeles used that opening to bring Peralta into the organization’s active decision-making.

Anderson’s injured-list placement underscores the flip side of that strategy. Shoulder inflammation is often treated as a “manage the risk” issue rather than something to test through in-season. By placing him on the 15-day IL, the Angels buy time for recovery while preventing the bullpen from absorbing the workload burden of both the injury and the replacement.

At this stage, the most practical question is how quickly Peralta can be folded into game plans. Whether he becomes a short-rest option, a situational lefty, or a deeper-inning reliever will depend on his recent readiness and how the Angels’ pitching staff has been managed in the weeks leading into this decision.

Going forward, Angels fans will likely watch for Peralta’s first appearance after the contract selection and for any updates on Anderson’s shoulder. That combination, the newly added arm and the injured bullpen piece on pause, should shape how Los Angeles balances innings in the final run of the season.
