Rangers Promote Robby Ahlstrom for MLB Debut, Bolster Lefty Depth
Texas plans to promote left-hander Robby Ahlstrom from Triple-A Round Rock, making his MLB debut as the Rangers navigate a full 40-man roster. In 2026 he owns a 2.76 ERA over 29 1/3 innings with a 28.4% strikeout rate and a 6.9% walk rate, featuring a four-seam fastball (93–94 mph) plus a newer sinker. With three lefty relievers already in the bullpen, Texas will likely need to clear space—potentially by optioning a rookie or moving a pitcher to the 60-day IL—to accommodate Ahlstrom.
