Chicago, IL (My Sportsbook) - Miguel Olivo belted a grand slam and Aaron Rowand knocked in three runs, as the Chicago White Sox crushed the Chicago Cubs, 12-3, in an Interleague matchup between Windy City rivals at Wrigley Field.

Magglio Ordonez finished 2-for-4 with a double and three runs scored, and Frank Thomas also doubled and scored three times for the White Sox, who have won five of their last eight.

Former Cubs draft pick Jon Garland worked six innings and picked up the relatively easy victory with great run support. Garland (5-6) yielded two runs on eight hits while striking out four and walking three for the Sox, who jumped out to a 6-0 lead in the first inning and never looked back.

Cubs starter Shawn Estes (6-6) was touched for all six first-inning runs on his way to the loss. Estes worked just that one frame, surrendering two hits and four walks.

Alex Gonzalez homered for the Cubs, who have dropped six of their last nine since a four-game winning streak earlier this month.

After suffering a 3-1 setback to the Cincinnati Reds in a brawl-filled game Thursday afternoon, the Cubs didn't put up much of a fight against their cross-town rivals.

The White Sox exploded for six runs in the first off Estes, who threw 52 pitches in the frame, including a 3-2 meatball to Olivo. Estes got a quick first out, but that was about the only thing he did right. Jose Valentin and Thomas drew consecutive walks and Ordonez followed with an RBI single to make it 1-0.

Then, after Carlos Lee fouled out, Estes walked Joe Crede to load the bases for Olivo, who worked a 3-2 count before launching a fastball into the seats in left-center field for his first career grand slam and a 6-0 lead.

The Cubs got a run back in the bottom of the frame when Gonzalez sent his seventh homer of the year over the left field seats and onto Waveland Avenue with one out. Then, they sent Todd Wellemeyer to the mound in the second inning, but he didn't fare much better than Estes, surrendering a two-out two- run single to Lee that scored Thomas and Ordonez for an 8-1 White Sox lead.

Wellemeyer calmed down long enough in the third to allow just a walk to Olivo, but the Sox struck again in the fourth inning, scoring four more runs off him to take a 12-1 lead.

Thomas got things going with a one-out walk and moved to third on Ordonez's double. Lee and Crede then followed with consecutive RBI singles before Rowand belted a two-run double to left field that gave the White Sox their 11-run advantage.

Troy O'Leary's two-out RBI double off Garland in the sixth produced the Cubs' second run, and Tom Goodwin ripped an RBI single in the seventh off David Sanders to make it 12-3, but that was as close as the they would come.
