BOSTON (AP) - Adrian Gonzalez put on a Red Sox jersey for the first time and immediately said what the Fenway faithful wanted to hear.

“I’m very excited to be in Boston and ready to beat the Yanks,” he pronounced Monday.

The Red Sox completed their deal for the All-Star first baseman, acquiring the slugger from the San Diego Padres for three prospects and a player to be named.

“We’re thrilled to be able to make this trade,” Red Sox general manager Theo Epstein said.

Boston sent minor league right-hander Casey Kelly, first baseman Anthony Rizzo and outfielder Reymond Fuentes to San Diego.

“It makes them a great team. He’s a heck of a hitter. That’s a huge addition for Boston,” Yankees general manager Brian Cashman said. “They just obviously improved themselves in a significant way. He’s one of the premier players in that position in the game.”

Gonzalez is entering the last year of his contract in 2011 and is due $6.3 million next year. Although the trade does not include a contract extension, Epstein said he’s “confident” a contract will be worked out.

“We’re going to try to get something so he will be here for a very long time,” said John Boggs, Gonzalez’s agent.

The absence of an announced extension could prompt calls to the commissioner’s office _ maybe from the New York Yankees _ for an investigation. If an extension isn’t formalized until after opening day, it wouldn’t count against the Red Sox for the 2011 luxury tax.

In five seasons with San Diego, Gonzalez has 161 homers and 501 RBIs. Including parts of two seasons with Texas, he has 168 homers and 525 RBIs. He hit .298 with 31 homers and 101 RBIs last season.

Gonzalez’s lefty swings put up big numbers despite him playing at pitcher-oriented Petco Park.

“I think he’s going to be a monster in Fenway Park,” Padres general manager Jed Hoyer said at baseball’s winter meetings in Lake Buena Vista, Fla.

Epstein, too, predicts Gonzalez will quickly take aim at the Green Monster in left field.

“We think he is going to wear the wall out,” Epstein said.

The Red Sox made a run at Gonzalez before the 2009 trading deadline and again last season, Epstein said. Gonzalez has been an All-Star the last three years and is two-time Gold Glover.
