CHICAGO (AP) – Tyson Ross struck out a career-high 11, and the light-hitting San Diego Padres broke out for a season-best nine runs in the sixth inning in a 13-3 rout of the Chicago Cubs on Thursday night. Ross (9-10) allowed one run, five hits and one walk in six innings to reach a career high in wins. He went 3-2 in five July starts, but gave up just four earned runs in 35 innings. Rene Rivera had three hits, including a home run, and drove in three runs. Will Venable had three hits and two RBIs, and Alexi Amarista and Chris Nelson also drove in two runs apiece with singles in the sixth-inning outburst that gave the Padres their highest scoring output this season. Edwin Jackson (5-11) left in the sixth because of a cramp in his right hand and took the loss.
