PHOENIX (AP) _ Tony Womack extended his hitting streak to 20 games, the longest in the majors this year, with a go-ahead double in the sixth inning as the Arizona Diamondbacks beat the Pittsburgh Pirates 7-5 Thursday night.

Arizona swept the three-game series and extended its franchise-record home winning streak to nine games.

Omar Daal (2-5) won for the first time in four starts since May 8 despite allowing three runs, six hits, four walks and a hit batter in six innings. He gave up a three-run homer to Bruce Aven in the fifth.

Matt Mantei pitched the ninth for his first save this year. He has spent most of the year on the disabled list with biceps tendinitis.

With the score 3-all in the sixth, Damian Miller and pinch-hitter Hanley Frias singled off Kris Benson (4-5), and Womack doubled down the right-field line. A throwing error by Aven in right made it 5-3.

Kevin Young had an RBI single in the seventh, but Arizona added a pair of runs in the bottom half on Steve Finley's second RBI single, which tied him with Sammy Sosa for the NL RBIs lead at 48, and Andy Fox's run-scoring double.

Giles had a run-scoring double in the ninth.

Daal survived bases-loaded situations in the first and fourth, retiring Aven and Mike Benjamin on inning-ending flyouts.

Fox, Arizona's right fielder, also robbed Benjamin in the first, racing to right center and sliding into the fence as he caught the ball for the first out of the game.

Benson, who had allowed just one earned run in 22 innings coming in, fell behind 2-0 in the first when Luis Gonzalez hit an RBI single and Finley doubled in a run.

Erubiel Durazo's RBI single made it 3-0 in the third, but the Pirates tied it in the fifth on Aven's homer.
