The Baltimore Orioles placed outfielder Colton Cowser on the 10-day injured list Monday with a broken left thumb.
Cowser, 25, sustained the injury sliding back into first base during Sunday’s 3-1 loss at Toronto.
The Orioles recalled outfielder Dylan Carlson from Triple-A Norfolk in a corresponding transaction.
Cowser was 2-for-16 with one homer, one RBI and six strikeouts in the season-opening four-game series against the Blue Jays.
He was the American League Rookie of the Year runner-up in 2024 and the No. 5 overall draft pick in 2021.
