CHICAGO – Anthony Rizzo, Starlin Castro and Mike Olt homered, and the Cubs stopped a four-game slide with a 12-5 victory over the 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.
Alexei Ramirez had four singles for the Sox, who had won four in a row. Conor Gillaspie went 2 for 4 with a walk in his first action since he was activated from the disabled list Wednesday after being sidelined with a bruised left hand.
The Sox got Adam Dunn back after he missed a game because of a bruised right calf, but rookie slugger Jose Abreu appeared to be playing through some sort of leg injury. Abreu, who is off to a terrific start with 12 homers and 35 RBIs, hobbled down the line each time he put the ball in play.
The Cubs jumped on Scott Carroll (1-2) for four runs in the third, sending 10 batters to the plate. Luis Valbuena singled in Kalish before Rizzo hit a drive to center for his seventh homer. Lake added a bases-loaded walk to make it 4-2.
Rizzo also walked and scored when Castro connected in the fourth. Castro went 1 for 15 with two walks during the Cubs' losing streak.
Carroll departed after Olt and Lake started the fifth with consecutive singles. The 29-year-old rookie was charged with 11 hits and six runs after he pitched well in each of his first two major league starts.
The Sox got two runs back in the fourth on RBI singles by Gillaspie and Tyler Flowers. But five Cubs relievers combined for five innings of one-run ball after Jake Arrieta's shaky outing. Brian Schlitter (2-0) got five outs for the win.
Arrieta allowed four runs, three earned, and nine hits in four innings. He pitched 5 1-3 scoreless innings in a no-decision against St. Louis on Saturday in his first start of the season.
NOTES: Sox ace Chris Sale (left arm) felt fine after throwing a bullpen session Wednesday, and manager Robin Ventura said the left-hander probably will throw again on Saturday. "He's progressing. He doesn't feel anything," Ventura said. "In talking to him, he says everything feels good." Ventura said he thinks the team will have a better idea this weekend about a rehab schedule for Sale. ... Cubs general manager Jed Hoyer said Jeff Samardzija's 126 pitches on Monday night "is just a story that should probably die." He said the front office, manager Rick Renteria and Samardzija are all on the same page. ... The Cubs send RHP Jason Hammel (4-1, 2.43 ERA) to the mound when they open a weekend series at Atlanta on Friday night. RHP Julio Teheran (2-2, 1.80 ERA) is slated to pitch for the Braves. ... Sox RHP Andre Rienzo (2-0, 4.50 ERA) and Diamondbacks RHP Brandon McCarthy (1-5, 4.67 ERA) square off Friday night in the opener of a weekend series in Chicago.
