PITTSBURGH — It was not quite a year ago that the Chicago Cubs and Pittsburgh Pirates met in the National League wild card game. Much has changed since then.

Javier Baez hit a grand slam and drove in a career-high six runs while major league ERA leader Kyle Hendricks pitched six scoreless innings as the Cubs won their 100th game of the season, routing the Pirates 12-2 on Monday night.

The Cubs improved to 13-3 against the Pirates this season.

“This year is what it is,” Pirates manager Clint Hurdle. “They’ve played extremely well against us. They’ve pitched extremely well against us. They’ve got a good team. There’s a lot of reasons why they’ve won 100 games.”

Baez helped the NL Central-champion Cubs reach triple digits in victories for the first time since 1935. He hit his second career grand slam in the fourth inning to extend Chicago’s lead to 5-0 and his two-run single capped a six-run sixth that made it 11-0.

Hendricks (16-8) dropped his ERA to 1.99 by scattering seven hits, striking out five and walking none. He has not allowed more than three runs in 22 consecutive starts.

Kris Bryant hit a two-run home run, his 39th, in the sixth to draw within one of NL leader Nolan Arenado of Colorado. It was also his 100th RBI.

The Pirates saw their hopes of a fourth consecutive postseason appearance dim even further with their third straight loss. They fell five games out of the second NL wild card with just six games to play.

Rookie Chad Kuhl (5-4) was rocked for five runs and eight hits in three-plus innings as his string of nine consecutive starts of giving up three runs or less ended.

“I thought I threw the ball pretty well until the fourth inning and then they started working some deep counts and things got away from me,” Kuhl said.

Matt Joyce and pinch-hitter David Freese hit back-to-back home runs off Pedro Strop in the eighth inning.
