Dominating only begins to describe the Cubs play at Wrigley Field this season. They have a 32-8 record at home and have won 14 straight inside the "friendly confines."
Ryan Dempster loves pitching in Chicago. Dempster is undefeated at home this season, with only two losses on the road.
Dempster gave up 10 hits and struck out four while pitching into the ninth inning.
Aramis Ramirez hit his fourth homer in the last three games as a solo shot in the fifth.
Eric Patterson also belted his first home run, a two run shot to propel the Cubs to their 7-1 victory and the sweep.
The Cubs will have Monday off and Baltimore will come in on Tuesday. Sean Marshall will make his first start of the season in place of Carlos Zambrano. Marshall will face Jeremy Guthrie.
