How Has Andrew Painter Re-Captured His Prospect Hype?

In the year following his selection 13th overall in the 2021 MLB Draft, Andrew Painter garnered significant attention within the baseball community. The young talent excelled in his first professional season, reaching Double-A by the end of the year at just 19 years old. His impressive performance led to numerous accolades, including the Paul Owens Award and Baseball America's inaugural MiLB Pitcher of the Year.

The Phillies were undoubtedly impressed with Painter's raw talent, as evidenced by his 1.56 ERA in 22 starts and an astonishing 38.7% K%.

However, Painter's progress was hampered by injuries. A UCL sprain during Spring Training and subsequent Tommy John Surgery sidelined him, causing him to return to action in late 2024. Despite his initial struggles, Painter returned to the major leagues in 2026, but his performance was far from impressive. His fastball suffered, with a wFA/C of -3.28, ranking among the worst in baseball during his initial MLB action.

Additionally, his secondary pitches showed a decline, with a negative slider (-0.65) and sinker (-0.50), while his curveball and splitter were merely above average.

Since being recalled from Triple-A Lehigh Valley, Painter has demonstrated significant improvement in his overall command. His Zone% - the percentage of pitches seen inside the strike zone - has deteriorated from 49.4% in his initial MLB stint to 43.7%, while since his recall, it has further decreased to 43.7%. Although a sweeping metric, this decline in Zone% reflects the quality of the pitches thrown, as well as their location.

Painter's H-Zone% (heart of the plate) and S-Zone% (along the edges of the zone) have also seen notable changes. In the first 12 starts, he threw 25.1% of pitches in the heart of the plate and 42.4% along the edges, while since his recall, these figures have dropped to 18.9% and 46.6%, respectively. This shift indicates that Painter is now throwing pitches that are more challenging to hit, as they target areas of the strike zone that are more difficult for batters to drive.

Moreover, Painter's Z-Contact% - the percentage of pitches seen in the overall zone that result in contact - has also decreased from 86.9% to 78.5%. This improvement highlights Painter's increased ability to throw effectively outside of the strike zone, as batters are less likely to make solid contact with his pitches. Painter's overall performance since his recall has been impressive, with a 2.93 ERA and a 0.98 WHIP.

In particular, he has proven to be a strong force in the later innings of games, despite initially struggling with first-inning pitching. Painter's batting average, on-base percentage, and slugging percentage in the first inning have all been significantly higher than his overall averages, indicating that he has been more susceptible to failures in this segment of the game.

However, his confidence has seemingly returned, allowing him to bounce back from rough first innings and deliver strong performances. Painter's changeup has been a game-changer for him, outperforming his previous splitter. The new pitch averages 90.1 MPH and has yet to allow any hits, striking out an impressive 46.7% of batters.

This changeup, coupled with his refined fastball and secondary pitches, has resulted in a formidable arsenal, ultimately leading to Painter's resurgence as a major league pitcher.
