SAN FRANCISCO (AP) - Chad Gaudin struck out eight in seven scoreless innings to build on his impressive monthlong stretch, All-Star Buster Posey hit an RBI double, and the San Francisco Giants beat the first-place Arizona Diamondbacks 2-0 on Friday night.
Hunter Pence added a run-scoring single as defending World Series champion San Francisco started a key series to open the second half by pulling within 5 1/2 games of the D-backs in the NL West race.
Arizona starter Ian Kennedy (3-7) was denied career win No. 50 yet again in his eighth try.
In his past four starts, Gaudin (4-1) has a 0.77 ERA, two earned runs in 23 1-3 innings. He has an 11-inning scoreless streak.
