The Rangers are selecting the contract of left-hander Robby Ahlstrom from Triple-A Round Rock, MLBTR has learned. The 26-year-old lefty will make his MLB debut the first time he gets into a game. Texas has a full 40-man roster, so they’ll need to make at least one corresponding transaction once the move is officially announced.
Texas originally acquired Ahlstrom alongside righty Albert Abreu in the 2022 trade sending catcher Jose Trevino to the Yankees. He’s regularly turned in solid ERAs and quality strikeout rates with shaky command — at least until this season. In 2026, Ahlstrom has taken his overall game to new levels. He’s sitting on a 2.76 ERA in 29 1/3 innings out of the bullpen and has fanned 28.4% of his opponents against a tidy 6.9% walk rate.
In the past, Ahlstrom has worked primarily off a four-seamer sitting 93-94 mph. This year, he’s begun to feature a sinker as well, throwing the pitch at a 21% clip thus far (in addition to a 35% clip for his four-seamer). Both fastballs are averaging 94.8 mph — the best mark of the mustachioed southpaw’s career. Ahlstrom also features an 85 mph slider, an 87 mph changeup and a show-me curveball that sits in the upper 70s (but has only been thrown at a 4% clip this year).
The Rangers have carried three lefties in the bullpen this season: Jacob Latz, Tyler Alexander and Jalen Beeks. All three have posted solid earned run averages, though the latter’s rate stats don’t really support his 3.86 ERA. If they plan to continue carrying all three, an optionable rookie like Peyton Gray or Gavin Collyer could be sent out in order to get Ahlstrom into the mix, though that wouldn’t clear a 40-man spot. Fellow lefty Robert Garcia, currently on the 15-day IL due to shoulder inflammation, has already missed more than six weeks and isn’t yet on a minor league rehab assignment, so moving him to the 60-day IL could potentially accommodate Ahlstrom’s promotion.
