The Texas Rangers dropped a gut-punch 4-3 decision to the Seattle Mariners on Thursday, September 10, 2026, at T-Mobile Park in what became a tale of two bullpens. Jacob deGrom was nothing short of dominant through six scoreless innings, and Texas held a 3-0 lead heading into the late innings — only to watch the lead evaporate in an instant when Jakob Junis couldn't record a single out. Julio Rodríguez did the damage with a three-run home run that swung the division rivalry decisively Seattle's way.

Jacob deGrom Delivers a Masterpiece, Offense Gives Him a Cushion

DeGrom was electric. The right-hander went six full innings, striking out 12 batters while allowing just one hit and zero walks. He didn't allow a single earned run. That is the kind of performance that deserves a win, and for six innings it looked like Texas was going to deliver one for him.

Joc Pederson provided the offensive punch, going 1-for-3 with a home run and two RBI. Nicky Lopez chipped in with a 2-for-2 night and an RBI to round out a Rangers lineup that scratched and clawed for a 3-0 cushion against Logan Gilbert, who was no slouch himself — the Seattle starter went seven innings and fanned 11 of his own.

Junis Collapse Opens the Door for Seattle Comeback

This game turned the moment Jakob Junis took the mound. He recorded zero outs and surrendered three hits and four earned runs — the entire margin of defeat delivered in a single, catastrophic appearance. The Rangers had handed their bullpen a three-run lead, and it was gone before they could blink.

Rodríguez's three-run blast was the killing blow. The Seattle outfielder went 1-for-3 with a homer and three RBI, accounting for every run the Mariners needed to complete a comeback from a three-run deficit. The metadata confirms this as exactly that — a 3-0 deficit overcome in a game that went the full nine innings.

Rangers Bullpen After Junis: Too Little, Too Late

After Junis's implosion, Texas turned to Robert Garcia and Robby Ahlstrom, who both threw clean innings — Garcia struck out two in one scoreless frame, and Ahlstrom matched that with two strikeouts of his own, though he walked two batters. The damage, however, was already done.

Seattle's relief corps told a different story. Gabe Speier handled the eighth inning with two strikeouts and no earned runs. Andrés Muñoz closed it out in the ninth, picking up the save despite issuing two walks. The Mariners' bullpen protected the lead when it mattered.

What's Next for the Rangers

Texas takes the loss in a division matchup they had every reason to win. DeGrom gave this team a gem, and Pederson and Lopez came through at the plate. The Rangers will need to sort out what comes after deGrom in high-leverage situations, because Thursday night made the answer to that question painfully clear. The series with Seattle continues, and Texas cannot afford to let another lead like this slip away.
