Hideki Matsui produced one of the greatest performances in Major League Baseball playoff history to help the New York Yankees beat Philadelphia 7-3 to win their 27th World Series title.

Matsui drove in six runs on three hits, including his third home run in the best-of-seven final, and became the first Asian to win the World Series Most Valuable Player as the Yankees claimed overall victory by four games to two.

"This is the best moment of my life," Matsui said. "It's awesome. It's just unbelievable. I'm surprised myself. All I can say is I feel so happy right now. It feels great."

The Yankees, with baseball's largest payroll at $201 million, extended the greatest legacy of championship success in North American professional sports by claiming their first crown since 2000. "It's back where it belongs," Derek Jeter, the Yankees captain, said as he held the trophy above his head. "This one is special."

Yankees designated hitter Matsui smashed a two-run homer to right field in the second inning, added a two-run single in the third and a two-run double in the fifth. The 35-year-old Japanese star matched the World Series one-game record for knocking in runs set by Yankees star Bobby Richardson in 1960. "He was just clutch," Joe Girardi, the Yankees manager, said. "Mattie has been a clutch player ever since I met him."

Matsui's heroics came in what could be his final game in a Yankees uniform since he was not signed beyond this season, but he achieved the dream he had when he joined the Yankees in 2003 of capturing a World Series crown. "I hope it works out for me. I love New York. I love the Yankees," Matsui said. "I hope something can be worked out."

Matsui batted .615 for the Series, going 8-for-13 with eight runs batted in, including two prior solo homers in the Series.

Andy Pettitte won his record 18th playoff game and second of the Series, the 37-year-old US southpaw having also taken a game-three victory. He had looked at retirement but signed a one-year deal to rejoin the Yankees. "This is what I came back for," Pettitte said. "I wanted to come back and play in this ballpark. I knew this feeling was going to be something special."

The Yankees won the crown in their first season in a new ballpark, just as in 1923 they claimed their first-ever Series crown in the debut year of the now-closed original Yankee Stadium across the road.

New York became the first World Series champion since Minnesota in 2001 to use only a three-man starting rotation of pitchers, including 2008 free agent signees Pettitte, C.C. Sabathia and A.J. Burnett.

Alex Rodriguez, the Yankee slugger whose season began with a February admission of taking steroids from 2001 through to 2003, finally claimed a World Series title after 15 years of failure. "I couldn't be more proud of these guys. Now we're standing here as world champions," Rodriguez said. "We're going to enjoy it and we're going to party."

New York brought in closing relief ace Mariano Rivera to secure the final five outs and the 39-year-old Panamanian right-hander did his job to touch off a wild celebration. "A rush goes through your whole body when you know it's over," Rivera said. "I was thinking about retirement but I think I'm going to stay around for another five years."

Philadelphia, the defending champions, failed in their repeat quest. No National League champion has taken back-to-back titles since 1976. "That just makes us more determined to come back next year," Charlie Manuel, their manager, said.

Matsui had been relegated to a pinch-hitter role in the past three games, played in Philadelphia under National League rules where pitchers bat for themselves. But he made up for lost time in game six. After Rodriguez walked to open the second inning, Matsui smashed a full-count pitch off Phillies starter Pedro Martinez high into the cold night air and it soared into the right-field stands to give the Yankees a 2-0 lead.

Philadelphia answered in the third when Carlos Ruiz tripled and scored on a Jimmy Rollins sacrfice fly. But Matsui struck again in the third, coming to the plate with the bases loaded and two out to face Martinez - loathed by Yankees fans after his years with the arch-rival Boston Red Sox. Matsui smacked a single up the middle to score Jeter and Johnny Damon, giving the Yankees a 4-1 lead.

In the fifth, Mark Teixeira singled in a run and Rodriguez walked to set up Matsui's double to centerfield to give the Yankees a 7-1 lead. Ryan Howard's two-run homer in the sixth was too little and far too late.
