Rangers selected the contract of LHP Robby Ahlstrom from Triple-A Round Rock.

Ahlstrom receives his first opportunity with the Rangers after compiling a strong 2.76 ERA, 0.95 WHIP and 33/8 K/BB ratio across 29 1/3 innings on the doorstep of the majors this season. He’s also notched a pair of saves during that span. The unheralded 26-year-old southpaw will operate in low-leverage spots for the Rangers initially.
