Scouting Report: Mitch Keller

Summary

Mitch Keller has shown strong consistency through early May 2026, posting a 4-1 record with a 2.87 ERA and 1.04 WHIP across 47 innings. He earned a quality start victory against Arizona on May 8, allowing 2 runs on 4 hits over 6 innings. However, in his subsequent start against Colorado on May 13, Keller retired the first 12 batters before collapsing in the 5th inning, surrendering 6 runs (including a 3-run homer to Mickey Moniak) in what became a 10-4 Pirates loss. The stark contrast between his dominant early performance and the explosive 5th inning suggests control issues or fatigue in high-leverage situations.
