National League Cy Young candidate Jake Arreita sent the Chicago Cubs to the Division Series on Wednesday night after tossing a complete-game shutout against the Pittsburgh Pirates.

Arrieta surrendered just four hits in the 4-0 Cubs win. He walked nobody and struck out 12.

The Pirates best chance to score came in the 6th inning when Arrieta hit two batters and had a batter reach on error to load the bases before inducing an inning-ending double-play.

The fireworks of the game came in the top half of the seventh when Pirates pitcher Tony Watson hit Arrieta -- intentionally I'm sure.

The Pirates took exception to the two hit batters in the 6th and decided to bean the Cubs hurler. It could have also been an attempt to get him out of rhythm.

Nonetheless, the ace couldn't be disrupted.

The Cubs scored on the first inning on a Kyle Schwarber single. They added two more runs on Schwarber's two-run homer. The fourth run came courtesy of a Dexter Fowler homer.

The Cubs will take on the Cardinals in the next round.
