After falling behind 2-0 and 3-1, K-Rod came back to even the count. A-Rod fouled off two more offerings before swinging through the eighth pitch of the at-bat.

"It was a pretty good one," said Santana, who watched on television in the clubhouse. "Pretty intense, but a pretty good one."

Alex Cora, a late addition to the lineup, hit a two-run single in a four-run second and the Mets took their first Subway Series since a rain-shortened two-game sweep at old Yankee Stadium in May 2008.

The city rivals meet again in the Bronx from June 18-20.

With a two-run shot in the second and a leadoff drive in the fifth, Bay tripled his home run total in his first season with the Mets. The All-Star slugger signed a $66 million, four-year contract in the offseason after hitting 36 homers and driving in 119 runs with Boston last year.

"Kind of like a big exhale," Bay said. "Hopefully, it's not a novelty anymore."

Bay broke out against the banged-up Yankees, who have dropped five of six to fall six games back of first-place Tampa Bay in the AL East. He went 4 for 4 and scored three times in Saturday night's 5-3 victory, then followed it up with another perfect night at the plate in front of a Citi Field-record crowd of 41,422.

"The ball was coming out of my hand pretty good and I had good action on my pitches, but I made some wrong decisions," Sabathia said.

Bay was hit in the back by an off-speed pitch from Sergio Mitre in the sixth. Plate umpire Marvin Hudson warned both teams, drawing arguments from Mitre and Yankees manager Joe Girardi.

Mets reliever Ryota Igarashi, just off the disabled list, dusted Kevin Russo with a high fastball in the ninth.

Santana (4-2) was sharp from the start in a marquee matchup with Sabathia (4-3), earning his first win in five outings since April 27 against the Los Angeles Dodgers.

The two-time Cy Young Award winner yielded six singles in 7 2/3 innings. He struck out five and did not go to a three-ball count until walking Nick Swisher with two outs in the seventh.

Francisco Cervelli followed with an RBI single off the top of the wall in the left-field corner, spoiling Santana's shutout bid. Cervelli thought the ball was a home run and umpires went inside for a look at the replay, but upheld the initial call.

"I think Citi Field is a little big for me," Cervelli said.

Santana was pulled after a pair of walks in the eighth. Pedro Feliciano retired Robinson Cano on a bases-loaded popout to preserve a 6-1 cushion.

Igarashi gave up an RBI single to pinch-hitter Juan Miranda before Francisco Rodriguez got two outs for his eighth save in 10 chances.

Derek Jeter greeted K-Rod with a run-scoring double, and Brett Gardner hit a slow RBI grounder to third. David Wright threw out the speedy Gardner on a close play, prompting arguments from Gardner and Girardi, who kicked at the dirt near first base.

Mark Teixeira reached on an infield single, setting the stage for Rodriguez vs. Rodriguez.

K-Rod also earned a five-out save Saturday night, combining for 49 pitches in the two outings.
