Padres 11, Cubs 1: Chase Headley drove in three runs and Yonder Alonso and Yasmani Grandal each homered as San Diego routed visiting Chicago to snap a four-game losing streak.

Smith had a two-run single and Alonso smacked a two-run homer to right-center field as the Padres scored four first-inning runs against Edwin Jackson (3-4). Grandal hit an opposite-field blast to left in the second and Headley added a two-run double that one-hopped the fence in right to make it 7-0.

Headley stroked a run-scoring single in the fourth to make it 8-0 before Chicago got on the board in the seventh on Welington Castillo’s run-scoring single. San Diego piled on three more in the bottom of the inning with Jedd Gyorko’s run-scoring double to right highlighting the frame.
