Cubs 11, Padres 7: Alfonso Soriano hammered a two-run homer onto Waveland Avenue beyond Wrigley Field to put the Cubs ahead for good as Chicago snapped its 12-game losing streak.

Soriano’s blast, one of eight homers in the wind-aided slugfest, gave the Cubs an 8-7 sixth-inning lead. Ian Stewart, Darwin Barney and Starlin Castro also homered for Chicago, which ended its longest skid since starting the 1997 season 0-14.

Chase Headley homered twice among his four hits and drove in three for San Diego, which also got long balls from Will Venable and Everth Cabrera.

San Diego ended a 26-inning scoreless streak in the first when outfielder Carlos Quentin, returning from knee surgery, doubled in Chris Denorfia. The lead was short-lived as Chicago plated two in the bottom half on Castro’s run-scoring single and Bryan LaHair’s RBI grounder.

Then the home run barrage began. Randy Wells (1-1) earned the win in relief, while Alex Hinshaw (0-1) took the loss.

San Diego has lost seven of eight and fell to 5-17 on the road.
