ST. PETERSBURG, Fla. -- On a night they raised the first championship banners in franchise history, the Tampa Bay Rays also exhibited why they feel capable of getting back to the postseason.

Carlos Pena hit a grand slam and drove in six runs Monday night, helping Scott Kazmir beat Chien-Ming Wang and the New York Yankees 15-5 in the home opener for the AL champions.

"We showed everything," Carl Crawford said after the young, confident Rays homered three times, amassed 17 hits, stole four bases, made some nice defensive plays and impressed manager Joe Maddon with how well they maintain focus on an emotional night.

It got so bad for the Yankees that first baseman Nick Swisher pitched a scoreless eighth inning, the first New York position player to take the mound since Wade Boggs used his knuckleball in 1997.

"It's one of those days," captain Derek Jeter said. "It was their day, an opportunity to celebrate what they did last season, and they had their way."

The Rays toasted last year's improbable worst-to-first turnaround by hanging two large blue and white division and league championship banners above the left-field stands during a festive pregame ceremony at sold-out Tropicana Field.

They spent the rest of the night pleasing the crowd of 36,973 by beating up on a division rival that shelled out more than $400 million in offseason acquisitions with hopes of regaining supremacy in the AL East.

Kazmir (2-0) allowed three runs and six hits in 6 2/3 innings, including Swisher's solo homer in the fourth and Melky Cabrera's RBI single in the fifth. The left-hander struck out six and walked none.

"Whatever could go wrong tonight went wrong," Yankees manager Joe Girardi. "It started with starting pitcher. Chien-Ming never got it going. We know he's much better than he's pitched so far."

Earlier in the day, New York's Alex Rodriguez resumed drills on a baseball field five weeks after hip surgery and said following the workout in Tampa that he eventually hopes to return as "good as new."

The Yankees could use some help with Jeter -- 1-for-his-last-20 -- struggling and Cody Ransom going 2-for-24 with two RBIs as A-Rod's replacement at third base.

Swisher may have been New York's most effective pitcher. After giving up a walk and Tampa Bay's 17th hit, he struck out Gabe Kapler and got Pena and Pat Burrell to fly out.

"I had fun with it. When am I ever going to have a chance to do that again? Probably never," said Swisher, who hadn't pitched in a game since he was a freshman in high school. "We know we didn't play very well. Got to find something to laugh about in that moment. I just happened to be the guy."

Pena had a two-run double in the first off Wang (0-2), who continued to struggle in his comeback from foot surgery that sidelined him for more than three months last season. The slugger drove in three of the eight runs charged to Wang in one-plus innings with the sixth grand slam of his career off reliever Jonathan Albaladejo in the second.

Burrell and Jason Bartlett also homered for the Rays, who got two more RBIs from hot-hitting Evan Longoria.

Longoria, the 2008 AL rookie of the year, has hit safely in all seven of Tampa Bay's games and has five homers and 12 RBIs.

"We have good young players coming off a very good season. My biggest concern is how we were going to react to success. And to this point, I'm pleased," Maddon said. "Gratitude and humility, I really believe in that. And I think our guys have channeled all the success properly to this point."

In two starts since foot surgery, Wang has allowed 15 runs on 15 hits in 4 2/3 innings. He failed to get through the fourth inning of a loss at Baltimore last week, and his earned run average ballooned from 17.18 to 28.93 after Monday night.

Tampa Bay got a boost from the return of B.J. Upton, who missed the opening week of the season to rehab his surgically repaired left shoulder. He was 1-for-3 with two walks and two stolen bases, and the 24-year-old made a crowd-pleasing, over-the-head basket catch of Xavier Nady's drive to the center-field wall in the second inning.

"That was about as good as it gets," Maddon said.

Upton also looked comfortable in his new role as a leadoff hitter, drawing a walk in the first inning before stealing second base and taking third as part of a double steal with Crawford.

Upton and Crawford scored on Pena's double, and Wang also yielded a run-scoring double to Burrell and RBI single to Gabe Gross to fall behind 4-0.
