Jon Lester pitched eight scoreless innings, Jason Heyward hit a two-run homer and the Chicago Cubs held off the 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.

Kris Bryant, Anthony Rizzo and Dexter Fowler each had three hits for the Cubs, who won their 11th in 13 games while extending their best start since 1900 to a major league-leading 40-16 record.

Adam Morgan (1-5) gave up three runs on eight hits in six innings to lose his fifth straight start.

Justin Grimm and Hector Rondon combined to allow four runs in the ninth inning, but Rondon got Ryan Howard to ground out to end it and get his 11th save.

Jorge Soler left after singling to left field in the third inning. Soler injured his left hamstring while running the bases. He'll have an MRI on Tuesday, Maddon said.

Kyle Hendricks (4-4, 2.84) opposes Phillies RHP Jerad Eickhoff (2-8, 3.93) in the second contest of the three-game set Tuesday night.
