Doug Davis matches up with Giants ace Tim Lincecum in Arizona's series opener against San Francisco

Posted: Updated:

PHOENIX (AP) -- Less than a week ago, Tim Lincecum and Doug Davis were locked in a pitchers' duel that resulted in the reigning NL Cy Young Award winner still searching for his first win of 2009.

Lincecum will get a fourth chance at victory No. 1 when he starts opposite Davis again tonight in Phoenix as the San Francisco Giants open a three-game road series against the Arizona Diamondbacks.

Lincecum (0-1, 3.86 ERA) may have failed to pick up a win for the Giants (6-8) in Saturday's 2-0 loss to Arizona (6-9), but the 24-year-old right-hander was outstanding in scattering five hits with a career high-tying 13 strikeouts in eight scoreless innings.

Davis (1-2, 2.57) was just as effective, giving up eight hits in eight innings to get his first win.

Lincecum will try to help the Giants win a fourth consecutive game after Bengie Molina's pinch-hit RBI double in the 10th inning gave them a 1-0 victory over San Diego on Wednesday.

The winning streak started Sunday as San Francisco took two of three from the Diamondbacks.

The Giants have dropped 15 of their last 20 at Arizona, getting swept in four games during their last visit to Chase Field on Sept. 15-18.

Lincecum is 3-1 with a 1.89 ERA and 63 strikeouts in 52 1-3 innings over seven starts in Phoenix.

Davis is looking to lead the Diamondbacks to consecutive victories after they took two of three from Colorado, winning 2-0 on Wednesday.
