Alberto Gonzalez hit a go-ahead single in the ninth inning, Kyle Blanks had a two-run homer and the San Diego Padres beat the San Francisco Giants 7-5 on Tuesday night for their season-best fifth straight victory. Nick Hundley doubled against Ramon Ramirez (2-2) to start the ninth, then Logan Forsythe sacrificed him to third before Gonzalez singled up the middle.
