The Los Angeles Angels selected Trey Mancini to their major league roster on June 8, 2026, and started him at first base, where he batted seventh in that night's game against the Houston Astros — his first big-league appearance since 2023.
The promotion followed a cluster of injury moves: the Angels placed Vaughn Grissom on the 10-day injured list with a left oblique strain and Adam Frazier on the 10-day injured list with right elbow inflammation. To create the necessary 40-man roster spot, Yoán Moncada was moved from the 10-day injured list to the 60-day injured list; Moncada had been on the shelf since May 22 with lingering right knee discomfort. The club also called up Denzer Guzman the same day, while Nolan Schanuel — just back from the injured list over the weekend — was given a day off because of lingering soreness.
Mancini’s return capped a long, stop-and-start run toward the majors. He signed an offseason minor league contract with the Angels, was assigned to Triple-A Salt Lake and, in 224 plate appearances there, produced a.273/.377/.464 line with six homers. He walked at a 14.3 percent clip and struck out at a 22 percent rate in Salt Lake, numbers the Angels evidently judged good enough to warrant a roster look when injuries created an opening.
The move also rewinds Mancini’s recent career arc: he sat out all of 2024, spent a half-season in Triple-A with the Arizona Diamondbacks organization in 2025 and had not been in a major league game since his 2023 stint with the Chicago Cubs, when he hit.234/.299/.336 over 79 games. He was originally traded from the Baltimore Orioles at the 2022 trade deadline and was part of the on-field mix that helped the Astros in that year’s postseason run, making a couple of strong defensive plays en route to the 2022 World Series title.
The immediate practical effect for the Angels was straightforward: Mancini takes live at-bats and a start at first base while two position players recover. The 60-day move for Moncada cleared the 40-man vacancy required to add Mancini without exposing another player, and Guzman’s recall expanded the club’s bench options for the short term.
The roster calculus that produced the call-up is also where the story frays. Mancini’s Triple-A numbers present a tidy counterpoint to his last big-league line — the walk rate and on-base improvement are real — but the club is reintroducing a player who struggled in 2023. That.234/.299/.336 slash line over 79 games for the Cubs is the unresolved fact that complicates the headline: his promotion is as much a roster stopgap as it is a vote of faith.
How long Mancini stays in Anaheim is the single, consequential unanswered question. Moncada’s shift to the 60-day injured list opened a longer-term spot on the 40-man, but the simultaneous 10-day placements for Grissom and Frazier suggest the Angels’ immediate needs could change as soon as those players start to bounce back. The club has not outlined a timeline for Mancini’s role; his continued presence will hinge on a mix of his performance, the health of the sidelined players and the Angels’ roster moves in the coming days and weeks.
