Trevor Cahill came off the disabled list to throw five innings of two-hit ball in his first start in nearly 16 months, and the Cubs beat the Milwaukee Brewers 4-0 Tuesday in the opener of a day-night doubleheader.
Mike Montgomery followed Cahill and pitched two innings, Hector Rondon worked the eighth and Joe Smith walked two in the ninth before Aroldis Chapman got two outs to close a three-hitter.
Cahill (2-3) also drove in a run with a safety squeeze bunt, and the Cubs added runs on a wild pitch and Addison Russell's sacrifice fly off Matt Garza (4-5).
Cahill allowed two walks and struck out Manny Pina with a runner on third to end the fifth on his 84th pitch.
Jason Hammel threw seven innings of two-hit ball, Anthony Rizzo jumped onto a wall to make a remarkable catch of a foul ball, and the Chicago Cubs beat the banged-up Milwaukee Brewers 4-1 on Tuesday night to sweep a day-night doubleheader.
Javier Baez hit a two-run homer while Hammel (13-5) struck out seven to extend his scoreless streak to 22 innings.
Rizzo wowed the fans when the first baseman jumped on the wall with both feet, leaned into the crowd and made a one-handed grab of Keon Broxton's popup.
Jon Lester (12-4, 2.93) faces RHP Jimmy Nelson (6-12, 4.07) on Wednesday night.
