Mitch Keller lasted just three innings against the Atlanta Braves as his season-long struggles against left-handed hitters continued. Alex Stumpf examines Keller’s extreme platoon splits, the mechanical issues potentially affecting his arsenal and why neither the cutter nor changeup has provided a reliable answer.
Can Keller make the necessary adjustments during the All-Star break, or has his decline become another major problem for the Pirates’ pitching staff?
