Arrighetti (thumb) allowed six runs (five earned) on six hits and four walks while striking out five across 4.2 innings in his rehab start Thursday with Triple-A Sugar Land. He also hit a batter and threw a wild pitch.
Arrighetti made his third rehab outing and his first at Triple-A, and though his results weren't great, he built up to 79 pitches (50 strikes). Assuming the right-hander comes out of his next bullpen session no worse for the wear, the Astros could activate him from the 60-day injured list to make a start during their series in Miami early next week. Arrighetti has been on the shelf since April 8 due to a right thumb fracture.
