2026 Fantasy Outlook
Speier added velocity in 2025, averaging a career-best 95.0 miles per hour on his four-seamer to produce a 33.3 whiff percentage that was seventh-best in the league for that pitch type. 50 of his career-best 82 strikeouts came via his fastball, which he tossed 45 percent of the time. The 30-year-old also achieved excellent results with his slider (.140 batting average against, 49.1 whiff percentage) en-route to the finest season of his career to date. Speier's 29.2 K-BB percentage ranked fourth among qualified relievers, while his 0.87 WHIP tied for fifth. The southpaw's emergence in high-leverage resulted in a career-best 24 holds (T-16th) for Seattle. After his breakout campaign, Speier should reprise his role as one of the Mariners' top setup men to open 2026. Read Past Outlooks
Signed a one-year, $2.12 million contract with the Mariners in January of 2026.

Latest Fantasy Rumors
In lead among lefty 'pen candidates
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.
