The call-up comes after Painter posted dominant numbers over his past six starts with the Phillies’ Triple-A affiliate Lehigh Valley IronPigs, where he recorded a 2.12 ERA, 42 strikeouts, and only 8 walks across 34 innings pitched, with his four-seam fastball velocity consistently sitting at 96-98 mph, a noticeable jump from the 93-95 mph average he posted earlier this season as he worked his way back from 2023 Tommy John surgery. Phillies pitching coach Caleb Cotham noted in a press briefing that Painter’s progress over the past month has exceeded the team’s expectations, with significant improvements to his slider command and changeup consistency that make him ready to face major league hitting. “We’ve been monitoring his workload and performance closely, and every single start he’s made in the last month has checked every box we had for him,” Cotham said. “He’s not just throwing harder, he’s making smarter pitch selections and limiting hard contact better than he ever has at the minor league level.” The call-up also comes at a critical time for the Phillies, who currently sit second in the National League East standings, 3 games behind the Atlanta Braves, as veteran starter Taijuan Walker was placed on the 15-day injured list earlier this week with right shoulder inflammation, leaving a gap in the team’s rotation. Phillies farm director Preston Mattingly added that Painter has nothing left to prove at the Triple-A level, pointing to his most recent start where he threw 7 shutout innings, allowed only 2 hits, and struck out 9 batters against the Triple-A Norfolk Tides, the Orioles’ top affiliate. Team leadership also confirmed that if Painter performs well against the Orioles, he will remain in the major league rotation for the remainder of the regular season and is in consideration for a spot on the team’s postseason roster as they push for a deep playoff run.
