NEW YORK (AP) – Cy Young Award winner Brandon Webb dominated a makeshift New York lineup Friday night, limiting the Mets to four hits and pitching Arizona to a 5-1 victory.

It was the eighth straight win for the Diamondbacks, their longest winning streak since 2003. Before Friday, Arizona had lost 15 of its last 18 games against the Mets and Mr. Webb was 1-6 lifetime against New York.

Chris Snyder provided all the offense Webb (5-3) needed with a two-run homer off John Maine (6-3) in the fifth inning. Then Stephen Drew added a three-run shot against reliever Guillermo Mota in the eighth.

Mr. Webb, who had a career earned run average of 0.43 in three previous starts at Shea Stadium, took advantage of the Mets, whose starting lineup looked like something out of a spring training game. Regular third baseman David Wright (back spasms) and center fielder Carlos Beltran (bruised knee) joined disabled list outfielders Shawn Green (broken foot) and Moises Alou (strained quad) on the sidelines.

That forced New York to start subs Julio Franco, David Newhan and Ben Johnson, along with fill-ins Endy Chavez and Damion Easley, who have been pressed into regular duty because of other injuries. They were easy pickings for Mr. Webb, who struck out eight and walked one.

Jose Reyes’ two-out single in the third was the Mets’ first hit, but he was thrown out trying to steal by Mr. Snyder when Arizona pitched out. In the sixth, Mr. Reyes beat out a bunt with two out for New York’s second hit and then stole his 30th base of the season. But Mr. Webb struck out Mr. Chavez, ending the inning.

The Mets scored in the eighth when Newhan singled, reached second on a throwing error by Mr. Reynolds and scored on a pinch single by Ruben Gotay.

Mr. Maine pitched around a leadoff single to Eric Byrnes in the first and a leadoff double by Conor Jackson in the fourth, stranding both runners.

In the fifth, Carlos Quintin hit a one-out double and Snyder followed with his fourth home run of the season on a 1-2 pitch from Mr. Maine.

There were two out in the eighth when Orlando Hudson and Mark Reynolds singled against Messrs. Mota and Drew followed with his second home run of the season.

NOTES:@ Mr. Franco, at 48 the oldest player in the majors, stole his second base of the season in the second inning. … Mr. Maine threw 103 pitches in six innings, allowing five hits with seven strikeouts and no walks.
