Randy Johnson (search) shut down Boston in his New York debut, dominating his new team's old rival. He outpitched David Wells, got help from Hideki Matsui and a rejuvenated Jason Giambi (search) and led the Yankees over the World Series (search) champions 9-2 Sunday night in the major league opener.

Already, there were bad omens for the Red Sox: Matsui leaped in left to rob Kevin Millar of a two-run homer in the third, Giambi stretched to reel in two bad throws by shortstop Derek Jeter, Alex Rodriguez made a diving stop at third on Edgar Renteria, and Tino Martinez made a backhand dive at first to prevent an extra-base hit by Johnny Damon.

By the time Matsui hit a two-run homer off Matt Mantei for a 8-1 lead in the eighth, it was almost piling on.

With Boston taking the field as champions for the first time in 86 years, the Red Sox returned to the scene of their improbable triumph staring directly at the 6-foot-10 Big Unit, brought to the Bronx to help the Yankees win their first title since 2000.

Giambi, back at first base following injury, illness and a reported admission of steroid use, received a pair of standing ovations from the sellout crowd of 54,818 and went 1-for-2 with a single and two hit-by-pitches.

Gary Sheffield, back from offseason shoulder surgery, hit a go-ahead single in a three-run third inning against Wells, and Martinez received two huge ovations in his first game in pinstripes since 2001.

Since New York moved within three outs of sweeping the Red Sox in the AL championship series last October, the Red Sox had won eight straight, becoming the first major league team to overcome a 3-0 postseason deficit, then blowing out St. Louis in the World Series.

But following an offseason of joy in New England, the Red Sox started with a thud, pitching poorly, making a pair of errors and losing their fifth straight season opener. New York had 15 hits off Wells and six relievers.

The usual swells and celebrities were on hand to watch the Yankees extend their winning streak in home openers to eight. A sign in left field expressed the hope of New York fans — "1918-2004-2090" — referring to the years of Boston's last two Series titles and projected date of its next.

Johnson was a model of quiet focus hours before the game, putting on a black undershirt, then a gray sweat shirt before sitting in front of his new locker near manager Joe Torre's office and looking ahead, gathering his thoughts.

Hitting Johnson is, well, a tall order — the New Yorker's playful front-page cartoon of him on the mound cut off at the neck.

He opened with a 93 mph pitch to Damon, and struck out Renteria and Manny Ramirez looking in the first, the latter on a smoking 97 mph heater. He got in trouble in the second, when Matsui grabbed Millar's fly ball and Jay Payton singled in the season's first run.

But Bernie Williams' sacrifice fly tied the score in the bottom half, and New York took a 4-1 lead in the third on Sheffield's double, Matsui's RBI single and a bases-loaded balk by Wells, who stepped back to start his windup and then stopped.

Rodriguez, vilified by Boston during the offseason and spring training, added a run-scoring single in the sixth off Blaine Neal and scored on Ruben Sierra's double.

Johnson allowed the one run and five hits in six innings and struck out six. Tanyon Sturtze and Tom Gordon finished with one-hit relief.

Wells, who pitched a perfect game for New York in 1998 and helped the Yankees win the World Series that year, was starting in place of Curt Schilling, his bloody sock in the Hall of Fame and the ankle it surrounded still recovering from surgery that followed the title.

Signed to fill the gap created by the departures of Pedro Martinez and Matt Clement, Wells made a shaky debut, allowing four runs and 10 hits in 4 1-3 innings.

It was a night of milestones — the first night opener at Yankee Stadium, the first time the Red Sox played as defending champions since 1919, when they opened with a 10-0 win over New York at the Polo Grounds behind a Babe Ruth home run.

Johnson made his 13th opening-day start, tying Roger Clemens for the lead among active pitchers.

New York, with the first $200 million payroll in baseball history, had a former All-Star in every spot in its starting lineup, the first time that happened in the major leagues since the Yankees did it on July, 24, 2003, according to the Elias Sports Bureau. In all, it added up to 53 All-Star appearances.
