Cubs: RHP Adbert Alzolay (blister on right middle finger) is scheduled to start Monday against Cleveland after being sidelined since June 7. “It's a big piece we've been missing,” manager David Ross said. “He's been one of the guys that have really given us ... consistent starting pitching, with real swing-and-miss. Has been a real asset to our rotation this year.” ... RHP Trevor Williams (appendectomy) threw a bullpen session Saturday and LHP Justin Steele (right hamstring strain) is scheduled to throw one on Sunday.

Duvall remained locked in after hitting a grand slam and two-run drive in Friday’s 10-2 romp. He had two-run shots in the first and third against Jake Arrieta (5-8), joining Derrek Lee in 2002 and Giancarlo Stanton in 2016 as the only Marlins with back-to-back multi-homer games.

Jesús Sánchez added his first big league homer, and Lewin Díaz went deep.

The only hit López (3-4) allowed was a single to shallow left by Eric Sogard in the second inning. The right-hander struck out seven and walked none.

Chicago’s Jason Heyward hit a solo homer in the eighth against Anthony Bass.

The Marlins added a run in the second when Jorge Alfaro singled and scored on Jon Berti's sacrifice fly.

Duvall extended the lead to 6-0 in the third with another two-run shot, launching one halfway up the bleachers in left-center for his 16th home run. That gave him three multi-homer games this season and 10 in his career.

The Cubs had not allowed 10 or more runs in back-to-back games at Wrigley Field since Aug. 18 and 19, 2015 against Detroit. They allowed one to score when a pop fly dropped between the mound and plate for a single and another on a wild pitch in losing for the fifth time in six games.
