Kyle Schwarber hit a grand slam and a three-run homer to power the Cubs past the Milwaukee Brewers 11-4 on Sunday, averting a three-game sweep. The Cubs moved into a first-place tie with St. Louis, with Milwaukee one game back.

Schwarber crushed a first-pitch slam deep into the second deck in right field off starter Zach Davies (8-4) with one out in the second inning for his 23rd home run of the season.

The slugger took Davies deep again in the fourth with an opposite-field shot to make it 7-0.

After the Brewers cut it to 7-3 in the fifth, Schwarber's infield single with two outs in the sixth kept the inning alive for pinch-hitter Victor Caratini, who hit a three-run homer off Milwaukee reliever Jeremy Jeffress.

Schwarber, who has struggled at the plate lately, reached base all four times while batting eighth in the lineup.

Christian Yelich's run-scoring double in the fifth, which extended his hitting streak to 16 games, chased Cubs starter Jose Quintana, who failed to get the win despite being staked to a seven-run lead. Quintana gave up four hits and three runs in 4 2/3 innings.

Brad Brach (4-3) retired the only batter he faced for the victory.

Davies was coming off his worst start, when he allowed seven runs in four innings of a 14-6 loss to Cincinnati on Tuesday. This time, he gave up seven runs and four hits in five innings. He had permitted only one earned run in 12 innings against the Cubs this season prior to Sunday.

Yu Darvish (3-4, 4.54 ERA) starts the opener of a three-game set at St. Louis on Tuesday night. Adam Wainwright (7-7, 4.63) pitches for the Cardinals.
