The Chicago Cubs earned a 3-1 win over the Chicago White Sox with a dominant pitching performance Thursday. The victory was capped by a four-out save from new closer Aroldis Chapman.

The three-headed monster

For the first time since Chapman was acquired, the Cubs used him, Pedro Strop and Hector Rondon in the same game. The trio combined for three innings, one hit and five strikeouts.

Strop and Rondon combined for the first five outs, striking out three batters in the process. Chapman then entered for his first save opportunity of more than three outs this season with a runner on third and two outs in the eighth inning.

Chapman struck out Melky Cabrera to end the threat. Of the four batters Chapman faced, none reached base and no balls were hit out of the infield.

In his first two appearances with the Cubs, Chapman has faced seven batters. None have reached base against him, and four have struck out.

John Lackey delivers a gem

Lackey was pulled after six innings of work as David Ross entered as a pinch hitter with two on and two out in the bottom of the sixth inning.

Lackey allowed a run in the first inning, but he held the White Sox scoreless after that. It was Lackey's first start with one or fewer runs allowed since June 8. It was also his first win since that date.

Lackey's fastball was the key in the outing. He held White Sox hitters to 1-for-10 with a pair of strikeouts in at-bats ending with the pitch.

Ben Zobrist is starting to heat up

Zobrist delivered a pair of hits Thursday, marking his third multihit game in his last six games. Entering this stretch, Zobrist was hitting .094 in 14 games in July.

The Cubs are 19-6 when Zobrist gets multiple hits this season.

In his last six games, Zobrist has succeeded in hitting fastballs. He is 5-of-14 (.357 batting average) in at-bats ending with a fastball in these games compared to 3-for-28 (.107) through his first 14 games in July.
