Yankees closer Mariano Rivera is congratulated on recording his 500th save.

NEW YORK (AP) — Mariano Rivera's 500th save included a surprising bonus: his first RBI.

On a New York night that belonged to baseball's most unflappable closer, Rivera became the second reliever to reach the milestone when the Yankees held off the punchless Mets 4-2 Sunday for a Subway Series sweep.

He joined Milwaukee's Trevor Hoffman, who has 571 saves, as the only major leaguers with 500. But what Rivera enjoyed best was his bases-loaded walk that provided a ninth-inning insurance run.

"I had one thing in mind — just try to do something," he said, before expounding on No. 500. "All of my teammates congratulated me, obviously. I think they were more happy than I was."

Chien-Ming Wang (1-6) won for the first time since June 15 last year and Rivera got four outs to secure the Yankees' fifth straight victory, all on the road.

In a fun twist, the 39-year-old Rivera even contributed on offense. The Mets walked Derek Jeter intentionally to get to Rivera with two outs, but he's proved to be no pushover at the plate. He fouled off a 2-2 pitch from Francisco Rodriguez before working out a walk for his first career RBI.

It was the third regular-season plate appearance for Rivera — and second in five days. With his teammates yucking it up in the dugout, he flied out against Atlanta on Wednesday, then finished off save No. 498.

"He looks good up there," Yankees pitcher Andy Pettitte said. "I think in Atlanta they gave him a take sign and he swung anyway."

Mark Teixeira hit a two-run double off Livan Hernandez (5-3) in a three-run first, when the Yankees had two of their four hits. Jorge Posada added a sacrifice fly.
