Arrighetti (1-0) earned the win Wednesday against the Rockies after tossing six innings of one-run ball, striking out 10 while allowing two hits and four walks.
The four free passes were a bit concerning for Arrighetti, who tossed 61 of his 100 pitches for strikes, but he delivered an excellent performance in what was a favorable matchup on paper. Given all the injuries in the Astros' rotation, Arrighetti isn't going back to Triple-A Sugar Land any time soon, and he lines up to make his next start next week on the road against the Guardians.
