PHOENIX (AP) - Josh Collmenter fought his way through five innings, Aaron Hill drove in two runs, and the Arizona Diamondback sent the San Francisco Giants to their sixth straight loss, 4-1 on Friday night.
The Giants still lead the NL West, but have lost nine of 10 to see a lead that was once 9 1-2 games dwindle to less than four.
The last-place Diamondbacks extended their misery behind a gritty effort by Collmenter (5-4) and by knocking around Tim Lincecum (5-5)
Paul Goldschmidt had two hits off Lincecum, raising his average to .577 against the two-time Cy Young Award winner.
Addison Reed worked a perfect ninth to close out his 17th save and Arizona's third win in 10 games.
Collmenter had lost two straight starts, allowing six runs in six innings against the Los Angeles Dodgers his last time out.
