Andrew McCutchen’s two-run homer capped a five-run fifth inning against struggling Adam Wainwright, and the Pittsburgh Pirates beat the St. Louis Cardinals 6-3 on Tuesday night. Wainwright remained stuck on 198 career wins a day after accruing his 18th year of major league service time. Wainwright retired the side in order in the first three innings before Ji Hwan Bae walked to lead off the fourth and scored on Connor Joe’s two-out single.
