Johan Santana gave the New York Yankees a firsthand look at the legitimate ace they turned down last winter. The two-time Cy Young Award winner pitched efficiently into the eighth inning, and the Mets got home runs from Jose Reyes and David Wright to top the Yankees 7-4 Saturday in the opener of a rain-shortened Subway Series.

Billy Wagner got four outs for his ninth save in nine chances _ one day after manager Willie Randolph held a closed-door meeting in response to remarks by the closer that some perceived as critical of his teammates.

After clearing the air, the Mets clocked reliever Kyle Farnsworth. They got key throws from outfielders Ryan Church and Carlos Beltran, beating Andy Pettitte (3-5) after Friday night's scheduled game was rained out.

Wright and Beltran each had three hits for the Mets.

Santana (5-2) started them off on the right track. He gave up three more homers but lasted 7 2-3 innings, his longest outing this year.

The Yankees initially pursued the left-hander in the offseason, then decided to keep their top young pitchers rather than trade them to Minnesota. Santana was dealt to the Mets for four prospects instead, and the Yankees have yet to get a win from youngsters Phil Hughes or Ian Kennedy this season.

Derek Jeter, Jason Giambi and Bobby Abreu homered, but little else went right for the Yankees. Jeter even lost a popup in the sun, soon after he was thrown out trying to stretch a single.

Santana recovered from a shaky start, snaring Giambi's leadoff liner in the fourth with reflexes that would rival those of any NHL goalie. He won his fourth straight decision and improved to 4-0 in his regular-season career against the Yankees.

Pettitte (3-5) allowed three runs in six innings, falling to 0-4 in his last five starts.

The Yankees put two on in the ninth, but Wagner set down the next three hitters.

Santana walked his first batter, Johnny Damon. One out later, Jeter hit his second home run of the season.

The Yankees had a great chance to expand their lead in the third, but ran themselves out of a potential big inning. Damon hit a leadoff single and was curiously waved around third base by coach Bobby Meacham when Abreu followed with a double to right-center.

The ball was cut off nicely by Church, and the relay throw from second baseman Luis Castillo nailed Damon on a close play when Brian Schneider blocked the plate perfectly with his left foot.

Santana escaped unscathed, retiring his next nine batters on 17 pitches. The Mets fought back in the fourth, when Pettitte walked two.

Consecutive singles by Church, Wright and Beltran made it 2-1. With two outs, Schneider drew a bases-loaded walk and Castillo dribbled an RBI infield single up the third-base line to put the Mets ahead.

Reyes homered leading off the seventh against Farnsworth and clapped his hands emphatically as he rounded first. After Church walked, Wright hit his eighth homer, an opposite-field shot that made it 6-2.

Both homers came on 2-2 pitches, and Farnsworth was booed by Yankees fans in the crowd of 55,093 as he walked off the mound. He has served up six home runs in 20 innings this year.

Giambi homered on an 0-2 pitch from Santana leading off the seventh, and Abreu added a solo shot in the eighth. Santana has allowed 11 homers in nine starts for the Mets after giving up an AL-high 33 with Minnesota last year.

Beltran tripled off Joba Chamberlain in the ninth and scored on Carlos Delgado's two-out single.

Notes:@ Before the game, Yankees manager Joe Girardi said it's possible Chamberlain could remain in the bullpen all season. GM Brian Cashman said Chamberlain will move into the rotation sometime in his career, but there's no timetable for that. "Nothing's changed," Cashman said. "He's a reliever. That's his focus right now. That's where he's needed. ... Stay tuned." ... With Jeter hitting third, Abreu batted second for the second time this season. ... Damion Easley was the DH for the Mets. ... Giambi's 185th homer with the Yankees tied Paul O'Neill for 15th place on the club list. ... Pettitte's first seven pitches were strikes. He fanned five of his first seven batters and finished with seven Ks, a season high. ... In the NL for the first time, Santana ran his interleague record to 17-4.
