Bracho (oblique) made his season debut Friday for Triple-A Sacramento, striking out two and walking one over a scoreless inning of relief in a 6-4 win over Las Vegas.
The 28-year-old right-hander was battling a left oblique strain late in spring training, but he appears to have made a full recovery. Bracho was a useful piece in Arizona's bullpen in 2018, but he's thrown just a single inning in the majors in the two seasons since.
