Anthony Rizzo, Starlin Castro and Mike Olt homered, and the Chicago Cubs stopped a four-game slide with a 12-5 victory over the Chicago White Sox on Thursday night.

Rizzo had three hits and scored three times as the Cubs salvaged the finale of the city series. Olt, Ryan Kalish, Nate Schierholtz and Junior Lake had two hits apiece in a game that took 4 hours, 7 minutes.

The Cubs put it away with five runs in the eighth, highlighted by Olt's first career grand slam. Maikel Cleto also hit Welington Castillo with a pitch with the bases loaded, ending the White Sox bullpen's shutout streak at 23 1-3 innings.

The Cubs finished with 15 hits after managing just five runs and 12 hits in the first three games against the White Sox.
