Anthony Rizzo capped Chicago's two-run 11th inning with an RBI single, and the Cubs beat the struggling Los Angeles Dodgers 6-5 on Wednesday night to complete the sweep.

Chicago's Matt Duffy tied it when he drove in Willson Contreras with a two-out single against Garrett Cleavinger (0-3). Duffy stole third and pinch-hitter Tony Wolters walked before Rizzo - who entered the game in the 10th - singled on a sharp grounder to left.

Alec Mills (2-0) got the win despite giving up two runs in two innings. Jake Marisnick homered, and the Cubs swept three from the Dodgers at Wrigley Field for the first time since 2008.

The Dodgers lost for the 13th time in 17 games since a 13-2 start. 

Los Angeles' Max Muncy homered for the second straight game when he connected against Adbert Alzolay in the fourth. He also hit an RBI double in the 10th and scored in the 11th.

Walker Buehler pitched six solid innings. But the Dodgers were unable to protect the late leads they built.

A throwing error by shortstop Corey Seager trying to force a runner at second in the eighth helped lead to a tying run for the Cubs. And in the extra innings, things really got wild.

Muncy put the Dodgers ahead 4-3 in the 10th with his two-out double off the ivy in left-center, though Justin Turner got thrown out trying to score on the play. The Dodgers challenged the play, but the call was upheld.

The Cubs tied it against Kenley Jansen in the bottom half on Joc Pederson's sacrifice fly to deep right against his former team. And after Muncy scored on Matt Beaty's force in the 11th, Chicago pulled it out in the bottom half.

Chicago's Adbert Alzolay allowed two runs and three hits in five innings. The right-hander struck out seven and walked one.

Zach Davies (1-2, 8.22 ERA) looks to end a string of five winless starts when the Cubs open a three-game series against the Pittsburgh Pirates on Friday. Davies hasn't won since April 4, when he beat Pittsburgh in his Cubs debut. RHP Trevor Cahill (1-3, 7.40 ERA) starts for Pittsburgh.
