Speas was promoted Tuesday to Triple-A Round Rock, Evan Grant of the Dallas Morning News reports.
Speas earned the level bump after delivering a 0.64 ERA with 47 strikeouts across 28.1 innings this season at Double-A Frisco. He hadn't allowed a run there since May 21. The 25-year-old did not pitch professionally in 2022, instead opting to take a job as a high school baseball coach, but he reported to the minor-league side of Rangers camp this spring and is now just one step away from reaching the majors.
