Garabito is listed as the Rangers' starting pitcher for Friday's game against the Angels.
Garabito has bounced between Triple-A Round Rock and the majors this season, and he was recalled Tuesday. He threw two-thirds of an inning that the same day, but he has a few multi-inning appearances in the majors and has worked as a traditional starter in the minors. As a result, Garabito should be able to provide more length than a typical opening pitcher, though the Rangers could elect to Jose Urena or Chase Anderson in bulk relief, if needed.
