$Signed a one-year contract with the Mariners in March of 2024.
Working through shaky June
PSeattle Mariners
June 22, 2025
Speier allowed two runs on one hit and one walk in one inning during Sunday's 14-6 win over the Cubs. He struck out one.
ANALYSIS
It's the most runs Speier has given up since April 29, and Sunday marked just the second time this year that he surrendered greater than one. The 30-year-old southpaw has endured a rough June so far, working to a 6.00 ERA through six innings this month, but he'll nonetheless remain an important weapon out of Seattle's bullpen as its lone left-hander. Speier owns a strong 2.86 ERA, 1.02 WHIP and 40:7 K:BB across 28.1 innings in 2025.

Latest Fantasy Rumors
In lead among lefty 'pen candidates
PSeattle Mariners
March 9, 2023
Speier "has taken the lead" over Tayler Saucedo and Brennan Bernardino among the the lefties vying for a spot in the Mariners' bullpen, Ryan Divish of the Seattle Times reports.
ANALYSIS
Divish cautions that the Mariners didn't carry a left-handed reliever for the bulk of last season and might not again. If they do, though, Speier appears to distanced himself with three scoreless appearances this spring. The 27-year-old was claimed off waivers from the Royals back in November.
