Astros RHP prospect Miguel Ullola threw a scoreless inning for Triple-A Sugar Land on Thursday.

Ullola allowed two hits but struck out one and avoided any damage. This is his sixth scoreless outing in seven appearances since being shifted into the bullpen. He did have one poor outing in that span, so his total stats as a reliever are three runs allowed on six hits in 6 2/3 innings with a 9/5 K/BB ratio. It’s not flawless work, but it’s good enough that he could join the Astros bullpen at some point over the summer.
