The Chicago Cubs beat the Pittsburgh Pirates in 12 innings on Friday after Pirates outfielder Gregory Polanco stumbled and fell while going after a routine fly ball. 

The Cubs had the bases loaded with one out in the bottom of the 12th when Matt Szczur lifted the ball to right. Polanco charged in and was attempting to settle under the fly ball when he lost his footing and fell as the ball dropped in. Starlin Castro then scored to give the Cubs an 11–10 victory. 

Chicago won despite blowing late leads of 7–1 (in the sixth) and 10–5 (in the eighth). A three-run home run by Andrew McCutchen made it 10–9 in the eighth before a Francisco Cervelli RBI single tied it in the ninth.
