PHOENIX (AP) - Rookie Brandon Webb shut down Pittsburgh for 7 2-3 innings and the Arizona Diamondbacks salvaged the final game of their three-game series against the Pirates 8-6 Sunday.

The 24-year-old right-hander, who relies mostly on a nasty sinker, scattered eight hits, struck out six and walked three.

Webb (2-1) allowed three runs. Two of them came on pinch-hitter Reggie Sanders' three-run homer off the first pitch from Eddie Oropesa, who relieved Webb with two outs in the eighth and Arizona leading 7-1.

Before that, Webb had shut out the Pirates for six innings after Kenny Lofton's leadoff double and Amaris Ramirez's RBI single in the first. Webb has a 2.02 ERA in his six big league appearances, the last five as a starter.

Lofton was 2-for-4 to extend his hitting streak to a career-best 18 games, longest in the National League this season, but was thrown out by home plate umpire Greg Gibson for arguing a called third strike in the seventh.

Six Diamondbacks had at least one RBI - including an NL-record four sacrifice flies - as Arizona scored in each of the first six innings.

Ramirez added a two-run homer in the ninth off Mike Koplove, the first this season by a Pirates' cleanup hitter.

Tony Womack, batting leadoff for the first time in more than a month, was 3-for-5 with two RBIs, one of them on a sacrifice fly. He stole a base and scored twice. David Dellucci added a triple and two RBIs for the Diamondbacks, who split the season series 3-3.

Pittsburgh never has won a season series against Arizona.

Junior Spivey, who hadn't played since bruising his ribs in Philadelphia on Tuesday, was 2-for-4 with a home run and scored twice.

Arizona pounded one-time Diamondback Jeff Suppan (4-4) for five runs and nine hits in four innings. Suppan was making his first career start against the team that made him the third pick in the 1997 expansion draft.

After winning his first four starts this season, Suppan is 0-4 in his last five.

With Arizona leading 2-1, Womack led off the third with a bunt down the third base line. Ramirez waited for the ball to roll foul, which it eventually did by about an inch. But by the time he grabbed it, the ball was barely touching the line again, and umpire Marvin Hudson emphatically ruled it was fair.

The next batter, Spivey, bounced one to Ramirez, whose throw to second failed to force Womack. Both runners scored on singles by Dellucci and Lyle Overbay to make it 4-1. Notes: It is the 13th time an NL team has had four sacrifice flies in the game. Seattle had five against Oakland in 1988 for the major league mark. ... The Pirates have scored in the first inning in all but one of Suppan's nine starts. ... Suppan was with Arizona when he pitched his first big league complete game against Pittsburgh on May 15, 1998. ... Arizona faces San Francisco for the first time this season on Monday.
