Paul Skenes and Jared Triolo help the Pirates blank the Cubs 5-0

CHICAGO (AP) - Paul Skenes pitched five effective innings while struggling with his location, and the Pittsburgh Pirates handed the Chicago Cubs another tough loss with a 5-0 victory on Tuesday night.

Skenes worked out of bases-loaded jams in the first two innings. The rookie right-hander allowed four hits and walked four, but he struck out six.

After Skenes (9-2) departed, Colin Holderman, Carmen Mlodzinski and David Bednar combined for four innings of one-hit ball.

Chicago had won six in a row - all on the road - before losing the first two in its three-game series against Pittsburgh at Wrigley Field. The Cubs are 4 1/2 games back in the race for final NL wild card after Atlanta beat Colorado 3-0 on Tuesday night.

Chicago right-hander Kyle Hendricks (3-11) struck out five while pitching five innings of two-run ball. He got the start after Justin Steele was scratched because of elbow soreness.
