Rocker is scheduled to make his next start Thursday against the Blue Jays in Arlington.
Rocker was called up from Triple-A Round Rock last week and ended up taking the rotation spot of fellow rookie and former Vanderbilt teammate Jack Leiter, who was moved to the bullpen. After submitting stellar numbers in the minors upon completing his recovery from May 2023 Tommy John surgery, Rocker continued to shine in his MLB debut this past Thursday, striking out seven and inducing 17 swinging strikes while allowing one earned run on three hits and two walks over four innings. Rocker was lifted after 74 pitches, and though the Rangers will likely be conservative with his workload over what projects to be two more starts this season, he should be a strong source of strikeouts down the stretch.
