CHICAGO — 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 — matching his season high — but the No. 1 overall pick in last year's amateur draft struck out six.
''He kept his composure,'' Pirates manager Derek Shelton said. ''He stayed calm even when the pitch count got up and he was able to finish up five for us.
''Overall, he's going to have to grind at times, as talented as he is. And today was one of those where he had to grind and he did a nice job.''
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 the final NL wild card after Atlanta beat Colorado 3-0 on Tuesday night.
''The first three innings, we played as good on offense as you can without scoring, unfortunately,'' Cubs manager Craig Counsell said. ''We didn't really create opportunities after that.
''We didn't score and that's not good enough.''
