Chicago,  IL (SportsNetwork.com)  - Mike Olt's first career grand slam was one 
of  three home  runs hit by the  Chicago Cubs as they avoided getting swept in 
the  Windy  City showdown  with a 12-5  victory over the  Chicago White Sox on 
Thursday. 

Anthony Rizzo and Starlin Castro each clubbed two-run homers for the Cubs, who 
snapped  a four-game losing streak with a 15-hit attack. They had been held to 
four  hits  in each of  the first three  games of this four-game home-and-home 
set. 

Rizzo  finished  3-for-5 with  a walk  and scored three  runs, while Olt, Ryan 
Kalish, Nate Schierholtz and Junior Lake all had two hits. 

Cubs  starter  Jake Arrieta labored  in his  second outing after beginning the 
season  on  the disabled list,  allowing four runs --  three earned -- on nine 
hits  in four  innings. 

"I'm  still not happy with it and I won't be until I get out there the next go 
round,"  Arrieta  said.  "Just  need  to  make  some  adjustments.  Be  better 
commanding the ball down in the zone." 

Relievers  Brian Schlitter  (2-0),  Zac Rosscup,  Neil  Ramirez, Justin  Grimm 
and  Wesley Wright  combined to limit the White  Sox to a run and four hits in 
the final five frames. 

Alexei  Ramirez collected  four hits and Tyler Flowers knocked in two runs for 
the White Sox, who had their season-high winning streak come to an end at four 
games. 

Scott  Carroll (1-2) struggled for the White Sox as he was tagged for six runs 
and  11 hits  in four-plus innings. He  had allowed just one earned run in his 
first two career starts. 

The Cubs  erased a 2-0 deficit  with a four-run  third. Kalish led off with a 
triple and scored on Luis Valbuena's single up the middle. Rizzo followed with 
a  smash  over the center-field  wall, and  Lake later forced  in a run with a 
bases-loaded walk. 

Castro  made it  6-2 with a drive  to left-center field in the fourth, but the 
White  Sox trimmed their deficit in the bottom of the inning on RBI singles by 
Flowers and Conor Gillaspie. 

The Cubs pulled away  later in the game as Olt's homer highlighted a five-run 
eighth. 

"It just seemed like  every inning  they had  a lot  of guys  on and they were 
knocking them in. They were swinging the bats tonight," said White Sox manager 
Robin Ventura.
