The Pittsburgh Pirates extended their season-best winning streak to five games Tuesday night, edging the St. Louis Cardinals 1-0 in a tense showdown at PNC Park. While pitching and defense carried the day once again, it was catcher Henry Davis’ highlight-reel tag at home plate that proved to be the difference-maker. After scoring 37 runs over their previous four games, the Pirates were locked in a pitching duel that required a more old-school brand of baseball — and they delivered. Rookie sensation Paul Skenes navigated early traffic in his 18th start, throwing five scoreless innings and striking out five, despite allowing five hits and a walk.
