PITTSBURGH (AP) — Ian Happ hit a go-ahead single in the 10th inning, lifting the Chicago Cubs to a 5-4 victory over the Pittsburgh Pirates on Thursday night. Nico Hoerner grounded to short to move automatic runner Mike Tauchman to third before Dansby Swanson walked and took second on a wild pitch. Happ then dropped a single into right, driving in Tauchman with Swanson scoring when right fielder Connor Joe bobbled the ball. Chicago, at 67-60, has won five of six to pull to three games back of the first-place Milwaukee Brewers in the NL Central.
