Joey Bart delivered a clutch performance for the Pittsburgh Pirates, hitting a walk-off single against the St. Louis Cardinals, securing a narrow 2-1 victory. With Isiah Kiner-Falefa on second base as an automatic runner, the Cardinals' reliever Chris Roycroft struggled under pressure, issuing back-to-back walks that loaded the bases. Veteran Andrew McCutchen was then unable to capitalize, grounding into a force-out at home plate. Bart's subsequent fly ball soared over Lars Nootbaar in left field, allowing Kiner-Falefa to score from third, sealing the game for the Pirates.
