Bronx, NY -- (Sports Network) - Hideki Matsui's monster night at the plate was capped by the Yankees swarming the infield for a boisterous celebration of their unprecedented 27th World Series title, including the first for Alex Rodriguez. Matsui tied a World Series record with six RBI in one game, Andy Pettitte threw into the sixth inning for his postseason-record 18th win and New York beat the Philadelphia Phillies, 7-3, to clinch the World Series championship in six games. Fittingly, the game ended with the playoff's best closer of all-time on the mound as Mariano Rivera retired Shane Victorino on a ground ball to second base. Matsui belted a two-run homer in the second inning and added a two-run single in the third, both off Pedro Martinez, and then drilled a two-run double off J.A. Happ in the fifth. The six RBI equals the mark set by the Yankees' Bobby Richardson in an October 8, 1960 Game 3 victory against Pittsburgh. It was a record-setting World Series for Phillies first baseman Ryan Howard, but one which he'd like to forget. Howard, who hit a two- run homer off Pettitte in the sixth inning, went 4-for-23 with a World Series- record 13 strikeouts over the six games. The Phillies were trying to become the first back-to-back NL champion since Cincinnati in 1975-76. Martinez (0-2), the losing pitcher in Game 2, left after giving up three hits and four runs over four frames.
