Painter (1-0) picked up the win in Tuesday's 3-2 victory over the Nationals, allowing one run on four hits and a walk over 5.1 innings. He struck out eight.
Making his long-awaited big-league debut, Painter fired 57 of 84 pitches for strikes and topped out at 98.7 mph with his four-seam fastball, although his velocity began to fade in the fifth inning. The 22-year-old right-hander made a clear early statement that he intends to stick around in the Phillies' rotation even after Zack Wheeler (shoulder) comes off the IL. Painter lines up to make his next start early next week on the road in San Francisco.
