The Seattle Mariners have sidelined left-handed relief pitcher Gabe Speier for at least two weeks due to inflammation in his left shoulder, the team announced Monday. The injury designation dates back to May 3.
To fill the roster spot, Seattle brought up Jose Suarez, whom they acquired off waivers from the Atlanta Braves over the weekend. Suarez, also a left-handed pitcher who works primarily in relief, was cut loose by Atlanta on May 1.
The 31-year-old Speier has become a cornerstone of Seattle’s bullpen since joining the team in 2023. He took the mound 69 times during his first season with the Mariners and appeared in 76 games in 2025. His 76 appearances ranked fifth-highest across Major League Baseball, while he maintained a 2.61 earned run average and 0.87 WHIP.
Speier’s most recent outing came on April 29, when he gave up one run while recording just two outs during Seattle’s 5-3 victory over Minnesota.
The California native from Santa Barbara previously played for Kansas City from 2019 through 2022 but didn’t find his groove until arriving in Seattle the following year. Throughout his career, he has pitched in 230 games with one start, compiling a 6-11 record and 3.60 ERA. He has recorded 226 strikeouts against 56 walks across 192 2/3 innings.
Seattle’s bullpen has taken another hit recently, as right-handed reliever Matt Brash was also placed on the injured list May 1 with minor inflammation in his right lat muscle.
The 28-year-old Suarez pitched in eight games for Atlanta this season, including one start, going 0-1 with one save and a 6.61 ERA. Before his brief stint with the Braves, the Venezuelan spent six seasons with the Los Angeles Angels from 2019-2024, making 61 starts during that time.
Over his major league career, Suarez holds a 22-30 record with a 5.35 ERA, striking out 383 batters while issuing 258 walks in 412 1/3 innings.
Seattle also promoted left-handed pitcher Josh Simpson from their Triple-A affiliate in Tacoma while sending right-hander Cole Wilcox back to the minors.
