According to ESPN’s Buster Olney, the Red Sox and Padres have a greed to a deal that will send first baseman Adrian Goznalez to Boston in exchange for several top prospects.

The team flew in Gonzalez, who had surgery Oct. 20 on his right, non-throwing shoulder to clean up the labrum, for a physical examination Saturday. While there was no official word on the physical, a team source told ESPNBoston.com’s Joe McDonald that Gonzalez “looked good.”

The Red Sox continued Saturday night to work on a long-term contract with him, a source, who indicated that the negotiation window will close at 2 p.m. ET on Sunday, told ESPNBoston.com’s Gordon Edes.

In exchange, the Padres would receive three prospects in pitcher Casey Kelly, first baseman Anthony Rizzo and outfielder Reymond Fuentes, according to a baseball source. The Padres also would receive a player to be named later, a source told Edes.

This deal works for all parties involved. The Padres couldn’t/wouldn’t pony up to pay Gonzalez, so they needed to get something for him before he hit the open market in 2012. The Red Sox desperately needed to add another middle-of-the-order bat and Gonzo fits the bill. He should love that short porch in right field at Fenway, although this guy can hit it out to all sides of the field. (He should love hitting in that wind tunnel that the Yankees call a ballpark, too.)

The only thing that’s unfortunate is that the Padres’ offense was about as explosive as wet tuna last year and now they just traded away their best hitter. This is a club that relied heavily on pitching last year and they’ll have to do it again this season because their lineup is the definition of weak.

Of course, maybe management knew that their success last year was more fluke than anything and decided that it was now or never when it came to trading Gonzalez. They didn’t want to hang onto him just to finish fifth next year (I’m not saying they would have – I’m just delving into the thought process of San Diego’s brass) and lose out on the chance to acquire Rizzo, Kelly and Fuentes. So they made the trade and will now deal with the fan outcry.
