(Best E Casino) - Brandon Webb will try to become the first 16-game winner in the majors this season when he takes the ball tonight for the Arizona Diamondbacks, who play the second installment of a three-game series versus the Pittsburgh Pirates at Chase Field.

Webb is 15-4 with a 3.04 earned run average in 23 starts this season, and 4-0 with a 2.63 ERA in his seven most recent trips to the hill. Webb continued his solid campaign on Thursday at the Los Angeles Dodgers, hurling eight dazzling innings of one-run ball in a 2-1 victory.

The right-hander, who is 6-1 in nine home starts this season, sports a 4-0 mark and a 2.41 earned run average over five career games against Pittsburgh. Webb defeated the Pirates on June 6 in the Steel City with seven frames of one-run, three-hit ball.

Arizona ended a two-game losing streak and won for the 10th time in 14 tries following Monday's 13-7 pounding of the Buccos in the opener of this series. Mark Reynolds homered and finished with three hits and three RBI to lead NL West-leading Arizona, which is 1 1/2 games ahead of the Dodgers in the division standings.

Stephen Drew drove in a pair of runs for the Diamondbacks, while starter Dan Haren earned the victory after yielding four runs on eight hits with eight K's in six innings of work. Arizona has now won 10 of Haren's last 12 starts.

Doug Mientkiewicz homered and ended with three hits for the Pirates, who fell to 1-3 on their 10-game, four-city road trip. Pittsburgh, which also received a home run from Jason Michaels, is a mere 19-35 as the visiting club this year.

Freddy Sanchez had three hits and knocked in a run in defeat.

Pirates starter Yoslan Herrera allowed three runs in 1 1/3 innings for a no- decision, and was optioned back to Double-A Altoona after the game. Jason Davis suffered the loss after giving up a pair of runs on four hits and one walk in 3 2/3 frames.

Zach Duke will take the ball for Pittsburgh on Tuesday and is 0-5 with a 7.23 earned run average in his last nine starts. Duke has dropped four outings in a row, including last Wednesday's meeting with Colorado. He allowed eight hits and six runs in five innings of a 7-4 loss.

The lefty has allowed five or more runs in five straight starts and is 0-3 with a 6.24 ERA on the road this season.

In three career starts versus the D'Backs, Duke is 1-1 with a 5.29 earned run average. He defeated Arizona in early June with six innings of two-run ball.

The Diamondbacks and Pirates split four games in Pittsburgh earlier this year.
