The Seattle Mariners gutted out a 5-4 comeback win over the Colorado Rockies on Friday, September 18, 2026, erasing a one-run deficit to take the road victory at Coors Field. Lazaro Montes and J.P. Crawford each went deep for Seattle, Randy Arozarena went 3-for-4, and Andrés Muñoz slammed the door in the ninth to earn the save. Carlos Vargas picked up the win in relief. It was exactly the kind of character win that matters in the final weeks of a regular season push.

Mariners Offense Gets the Job Done Despite Woo's Rough Night

Bryan Woo had a tough go of it on the mound, giving up 10 hits and 3 earned runs across 5.1 innings. He struck out four but couldn't miss enough bats against a Colorado lineup that was swinging freely. Jake McCarthy led the Rockies with a 3-for-5, 2-RBI night, and Connor Norby and Cole Carrigg each chipped in three hits of their own. Colorado came ready to hit.

But Seattle's offense answered. Randy Arozarena was relentless at the plate, going 3-for-4 and getting on base repeatedly to set the table. J.P. Crawford provided the thunder, launching a solo home run to give the Mariners a crucial run. Lazaro Montes added his own blast — a solo shot that proved pivotal in the final margin. Both homers were the kind of individual moments that swing close games.

Bullpen Carries Seattle Home

After Woo's exit, the Mariners turned to a parade of relievers, and the group largely delivered. Seranthony Domínguez was sharp over 1.1 innings, striking out two while allowing just one hit and no runs. José A. Ferrer held the line with 0.2 innings of one-hit, scoreless work. Carlos Vargas threw a scoreless third of an inning to pick up the win — the right place at the right time.

Andrés Muñoz got the ball in the ninth and was electric, striking out two while allowing one hit and no runs to nail down the save. When Muñoz is on, he's as reliable as it gets at the back of a bullpen.

Turning Point: The Ninth-Inning Lead and Muñoz Closing It

The decisive moment came when Seattle took a one-run lead heading into the final frame, flipping a deficit into an advantage late in the game. Colorado closer Jordan Romano took the loss after allowing 2 hits and 1 earned run in his inning of work. Once the Mariners grabbed that lead, Muñoz made sure it held, retiring Colorado in order with two strikeouts to secure the final out.

The comeback nature of this win — overcoming that one-run deficit — made it more than just a box-score result.
