The Seattle Mariners placed right-handed starter Bryan Woo on the 15-day injured list with right forearm inflammation on Tuesday and designated right-handed reliever Matt Festa for assignment.
The move involving Woo is retroactive to Saturday.
The team also claimed right-hander Ryan Jensen off waivers from the Chicago Cubs and recalled right-hander Ryder Ryan from Triple-A Tacoma.
Woo, 23, has made 11 big-league starts, going 1-3 with a 4.75 ERA through 55 innings with 17 walks and 60 strikeouts.
In Woo’s nine starts at Double-A Arkansas prior to his June 3 call-up, he was 3-2 with an ERA of 2.05. Woo walked 12 and struck out 59 over 44 innings pitched.
Ryan, 28, has yet to appear in a big-league game. He made 33 appearances with Tacoma this season, going 3-2 with two saves, a 3.76 ERA, 40 strikeouts in 40 2/3 innings and 15 walks.
Jensen, 25, appeared in 30 games (six starts) between Double-A and Triple-A for the Cubs, going 2-7 with a 5.77 ERA, compiling 46 walks and 66 strikeouts. He was a first-round pick by the Cubs (No. 27 overall) in 2019.
Festa, 30, spent time between Seattle and Triple-A Tacoma in 2023, throwing nine innings for the Mariners and allowing four runs while walking 12 and striking out 13.
