Tim Hudson had another rough start, costing the San Francisco Giants ground in the playoff chase and raising some big questions considering that his next scheduled start is against Clayton Kershaw and the Los Angeles Dodgers. Hudson allowed four runs in the first inning and the Giants were held to three hits in a 5-0 loss to San Diego on Friday night that dropped them 3 1/2 games behind the Los Angeles Dodgers in the NL West race. The Giants' lead in the wild-card race is down to one game over Pittsburgh, but their magic number to clinch a wild-card spot dropped to four thanks to the Pirates' 4-2 victory against Milwaukee. The Dodgers won 14-5 at the Chicago Cubs.
