Rapid Reaction: Cubs 8, White Sox 3

CHICAGO -- The Chicago Cubs' fifth consecutive interleague victory was a breeze after an 8-3 victory Thursday over the Chicago White Sox.

How it happened: Cubs starter Travis Wood got to White Sox starter Jake Peavy in more ways than one. Wood not only pitched the Cubs to a victory but he also hit a grand slam in the fourth inning to power the offense. Wood went six innings, giving up two runs on six hits. Peavy lasted just four innings, giving up six runs on eight hits.

What it means: The Cubs won all three games played between the teams this week and were leading in the game that was eventually postponed. There is still no official makeup date for the rained out game, but both teams have off days on June 24. The White Sox were confident at the start of the week over their better brand of baseball of late, but are now 3-3 over a stretch of 32 games where they face just one club with a record over .500.

Outside the box: Wood's grand slam was the first one for the Cubs this season. Anthony Rizzo hit the most recent one last season. The last Cubs pitcher to hit a grand slam was Jason Marquis when he did it in 2008 at New York's Shea Stadium. The last time a Cubs pitcher hit a grand slam at Wrigley Field was in 1972 when Burt Hooton had one.

Off beat: The White Sox were getting some breaks Thursday, they just couldn't do anything with them. In the second inning, a Tyler Flowers broken-bat line drive fooled Cubs third baseman Luis Valbuena into thinking it was hit to his right when it was really to his left. Flowers ended up with a single. In the third inning, Alexei Ramirez hit a ball up the middle that was about to be fielded by Cubs second baseman Darwin Barney, before it hit off the bag for another single.

Up next: The White Sox will send right-hander Dylan Axelrod (3-3, 4.21 ERA) to the mound Friday in the opener of a three-game series at Oakland at 9:05 p.m. CT. The Cubs will send Matt Garza (0-0, 4.00) to the mound Friday in the opener of a three-game series against the Arizona Diamondbacks at 1:20 p.m. at Wrigley Field.
