Aubrey Huff hit a tying homer off All-Star closer Heath Bell leading off the ninth inning and Mike Fontenot brought in the go-ahead run with a bases-loaded walk with two outs in the 12th, helping the NL West-leading San Francisco Giants beat the last-place San Diego Padres 6-2 on Thursday night. The bullpen collapse extended the Padres' losing streak to six games, tying their season high.
