Mariners Recall Domingo González For MLB Debut

The Mariners on Monday recalled righty Domingo González from Triple-A Tacoma, per a club announcement. Lefty Jose A. Ferrer has been placed on the paternity list in a corresponding roster move. González will be making his major league debut when he first takes the mound.

A waiver claim out of the Braves organization last August, González has rebounded from last year’s middling numbers with a big start to his 2026 season. After posting a combined 4.47 ERA, 20% strikeout rate and 11.3% walk rate between the Atlanta and Seattle organizations in 2025 (Double-A and Triple-A combined), he’s pitched 15 frames of relief and notched a tidy 1.80 ERA. González has fanned 23.7% of his opponents and cut his walk rate to an immaculate 3.4%. He’s faced 59 hitters and has the same number of walks/hits allowed (14) as strikeouts recorded. Half the batted balls against González this season have been grounders — up from 44% last year.

The 6′, 185-pound González works off a classic four-seamer/slider pairing. He’s averaged 93.1 mph on the heater this year and is sitting 85.3 mph on his slider. It’s not an overpowering profile from a velocity standpoint, but González has generated chases on balls off the plate at a 30.5% that’s about a percentage point north of the major league average and logged a 12.7% swinging-strike rate that’s nearly two percentage points north of par in MLB.

This is the second of three minor league option seasons for González. He can be freely shuttled between Seattle and Tacoma for the remainder of this year and next, although with several key injuries in the Mariner relief corps at the moment, all of Seattle’s depth arms have some opportunity to make an impression. The M’s have been without hard-throwing sinker specialist Carlos Vargas all season, and they’ve lost Matt Brash (lat inflammation) and Gabe Speier (shoulder inflammation) to the 15-day IL recently. Neither Brash nor Speier is necessarily expected to be out long term, but their absence has opened at least short-term windows for not only González but also Alex Hoppe, Nick Davila and Josh Simpson.
