Sergio Alcantara scampered home when second baseman Wilmer Difo mishandled a popup in the 11th inning, and the Chicago Cubs beat the Pittsburgh Pirates 6-5 on Thursday night for their third straight win.

Rafael Ortega and Ian Happ homered for Chicago, and Alcantara logged the first three-hit game of his career. Codi Heuer (6-2) got three outs for the win.

Alcantara began the 11th on second base and advanced on Ortega's sacrifice bunt against Sam Howard (2-3). Happ then sent a high fly to second, where Difo committed the game-ending error.

It's the first three-game win streak for the Cubs since a five-game run from June 8-13.

Pittsburgh's Steven Brault (0-3, 4.57 ERA) takes the mound Friday against Cubs right-hander Alec Mills (6-6, 4.32 ERA).
