Jon Lester dominated for eight innings, and the Chicago Cubs bullpen was just good enough in the ninth for yet another victory.
Lester pitched eight scoreless innings, Jason Heyward hit a two-run homer and the Cubs held off the host Philadelphia Phillies 6-4 on Monday night.
Lester (7-3) improved to 6-0 in eight career starts against the Phillies while lowering his ERA against them to 1.46. He struck out nine, walked none and allowed four hits.
"He's really on top of his game right now," Chicago manager Joe Maddon said.
So are the rest of the Cubs. Kris Bryant, Anthony Rizzo and Dexter Fowler each had three hits as Chicago won for the 11th time in 13 games while extending its best start since 1900 to a major league-leading 40-16.
Philadelphia scored all of its runs in the ninth after Maddon elected not to send Lester out for an attempt at a shutout. Lester threw 95 pitches and had to wait out a lengthy top of the ninth.
"It was really an easy decision once we got the sixth run," Maddon said. "It just didn't play out right. We had to fasten our seatbelts in the ninth."
Lester said he didn't lobby hard to stay in the game. "I told Joe I was fine, but I also told him that he's the manager," he said. "I've tried before with him, and I think I've won maybe one in the last two years."
