2026 Fantasy Outlook
With his 2024 internal brace surgery behind him, Brash rejoined Seattle's bullpen last May and stepped right back into the setup role he operated in before his procedure. The 27-year-old kicked off his 2025 campaign with a 19-game scoreless streak, an impressive feat given his lengthy absence. Brash featured more sliders (61 percent pitch usage), sinkers (22 percent) and changeups (12 percent) than he's thrown in past seasons, relying far less on his four-seamer (five percent) and knuckle curve that were integral parts of his pre-surgery arsenal. The right-hander still battled command issues - his 9.0 percent walk rate was a career-best, but still below league average - but his newly featured sinker and changeup helped induce plenty of ground balls (54.7 percent clip). Assuming no health setbacks, Brash will open 2026 as the Mariners' primary eighth inning option, but he certainly has the talent to step into full-time closing duties if needed. Read Past Outlooks
Signed a one-year, $1.55 million contract with the Mariners in January of 2026.
Diagnosed with Grade 1 strain
General manager Justin Hollander said Tuesday that Brash was diagnosed with a Grade 1 strain in his right lat, Shannon Drayer of SeattleSports.com reports.
Analysis
Brash has suffered multiple right lat strains this season, though Hollander noted that his latest injury is in a different spot than the one that kept him out for three weeks in May. He also said that the 28-year-old righty is facing a longer stint on the IL this time around and is likely to return sometime around late July or early August. Until then, Jose Ferrer, Gabe Speier and Eduard Bazardo figure to work more often in high-leverage situations.

If you play in only nonkeeper league formats, you do not need to read on any further. Brash had Tommy John surgery, which included installing a brace around the repaired ligament, and that surgery was completed May 10, 2024. Best-case scenario is he makes it back on the mound in Seattle by Memorial Day weekend, but these situations rarely work out in those best-case scenarios. The more likely outcome is Brash is back in the big leagues closer to the mid-summer classic and resumes his high strikeout and high walk ways while frequently showing up on Pitching Ninja clips. Pre-injury, his slider was one of the more unhittable pitches in all of baseball and he threw the pitch 51 percent of the time to hitters. Unfortunately, everything else he threw in 2023 was too hittable, as the league hit anywhere from .300 to .429 against his other offerings. Command is always the last thing to come back in these situations, and Brash did not have much to spare before his injury. He will likely be more fun to watch in social media clips than he will be to have on your roster in 2025.

Latest Fantasy Rumors
Thriving in high-leverage role
Brash owns a 1.98 ERA and 1.10 WHIP across 13.2 innings since the All-Star break.
Analysis
Brash is tied for the MLB lead with 14 appearances in the past 30 days. He recorded just his second save of the season August 4, but the 25-year-old has also notched 17 holds and eight wins across 57 appearances. He's a sneaky source of fantasy value with a slightly boosted ceiling after the Mariners traded closer Paul Sewald at the deadline.
