Rapid Reaction: Cubs 12, White Sox 5

CHICAGO -- The Chicago White Sox couldn't close out the season sweep against the Chicago Cubs, falling 12-5 in the final game between the teams this season.

How it happened: Scott Carroll was unable to match the success of his first two starts, giving up six runs and 11 hits with two walks over four innings. The Cubs' offense was powered by home runs from Anthony Rizzo, Starlin Castro and Mike Olt, who added insurance in the eighth inning with a grand slam. Alexei Ramirez had four hits for the White Sox, and Conor Gillaspie had a pair of hits in his first start since coming off the disabled list because of a hand bruise.

What it means: Carroll wasn't going to dominate everybody and now the key will be to see how he bounces back when he starts again next week at Oakland. Without command of his sinker, he was left to do battle with his fastball and the Cubs went on the attack. The plus of being a newcomer on the major-league level is the limited scouting reports on you. The minus is that your leash isn't very long when you struggle.

Outside the box: Ramirez had cooled off since putting up 40 hits in the opening month, but he looks to be locked in again. Even with all his offense, he didn't have a three-hit game this year, much less a four-hit one that tied a career high. After going back-to-back games without a hit for the first time in the previous series at Cleveland, Ramirez had a hit in three of the four games against the Cubs.

Off beat: It took a misplayed fly ball in right field and a hit batter with the bases loaded to end the 23 2/3-innings scoreless streak from the White Sox's bullpen. Reliever Maikel Cleto grazed the Cubs' Welington Castillo with a pitch in the eighth inning to allow the streak-busting run to score. The next batter, Olt, then crushed a grand slam. The relievers entered Thursday's game with a 1.46 ERA over their previous 17 (61 2/3 innings).

Up next: White Sox right-hander Andre Rienzo (2-0, 4.50 ERA) will face the Arizona Diamondbacks on Friday in the opener of a three-game interleague series. The Diamondbacks will counter with former White Sox pitcher Brandon McCarthy (1-5, 4.67) in the 7:10 p.m. start from U.S. Cellular Field.
