Pirates right-hander Daniel Hudson crouched on the infield and slammed his fists into the grass -- a gesture of frustration. He had battled throughout the 11th inning, but with two outs and runners on the corners, his full-count slider slipped past catcher Elias Diaz, allowing Giants center fielder Denard Span to score from third. And that moment lifted San Francisco to a 2-1 extra-innings win Saturday at PNC Park.
