Philadelphia Phillies right‑hander Andrew Painter struggled in his latest start against the Oakland Athletics on May 7, 2026, raising alarm bells about his fastball effectiveness. Todd Zolecki of MLB.com noted the velocity dip is more than a streak of bad luck, and the numbers reveal a clear downward trend.
While Don Mattingly’s tenure has steadied the club after a rocky beginning under Rob Thomson, the team still battles inconsistencies, from Alec Bohm’s offensive slump to Painter’s looming fastball problem. The front office now faces a choice: adjust mechanics, trim innings, or explore a bullpen role.
Why the fastball matters for the Philadelphia Phillies
The fastball is the cornerstone of Painter’s repertoire; when it loses zip, hitters sit on his secondary offerings, inflating his ERA and limiting strikeout potential. Opponents are now batting .285 against him, up from .242 last season, and his whiff rate has dropped 12 points.
How the blowup against Oakland unfolded
In the Athletics game, Painter surrendered multiple runs early, never reaching the second inning with a fastball that failed to exceed 92 mph, a noticeable drop from his career‑average velocity near 95 mph. The coaching staff admitted the need for a mechanical tweak during the post‑game interview.
Key details from the report
“Painter isn’t simply getting unlucky; there is a real problem, and it has to do with his fastball,” wrote Todd Zolecki, citing advanced spin‑rate data that showed a 15% decline compared with last season. The Sporting News analysis added that the Phillies’ bullpen depth could absorb some starts if Painter continues to lag.
Key Developments
- Todd Zolecki of MLB.com identified the fastball as the primary cause of Painter’s recent struggles.
- Painter’s latest start versus the Athletics resulted in a blowup performance, marking his third sub‑par outing of the season.
- The Phillies’ overall season has been described as “rough,” with early‑season turbulence under Rob Thomson before Don Mattingly took over.
What the Phillies could do next
Instead of simply watching the decline, the club may experiment with a lower‑arm slot or add a dedicated fastball coach, a move that could restore velocity and spin efficiency. If Painter’s fastball improves, the rotation could stabilize, keeping the Philadelphia Phillies in the NL East hunt; if not, the bullpen will shoulder a heavier load, potentially affecting the team’s playoff trajectory.
Andrew Painter has been a mainstay in the Philadelphia Phillies rotation since his debut, logging 112 innings this season. The numbers reveal his strikeout‑per‑nine innings rate has slipped from 9.2 to 7.4, while his walk rate crept up to 3.6 per nine. The decline coincides with a subtle change in his arm angle, observed by the team’s video analysts. MLB.com highlighted that his spin efficiency fell from 78% to 66%, a metric that directly impacts perceived velocity. The Phillies’ front office brass is reportedly reviewing a plan that could involve a short‑run reliever role to rebuild his arm strength before returning to the rotation.
Why is Andrew Painter’s fastball specifically under scrutiny?
Because his fastball accounts for over 60% of his pitches, a drop in velocity directly raises hitters’ contact rates, according to the Sporting News analysis.

The team sits at a sub‑.500 record, with early struggles highlighted by a rough start under former manager Rob Thomson before Don Mattingly’s appointment, as noted in the source.
What adjustments could the Philadelphia Phillies make to help Painter?
Potential fixes include mechanical tweaks to his arm angle, hiring a dedicated fastball coach, or shifting him to a short‑run reliever role, options discussed by analysts based on his spin‑rate decline.
