LAKE BUENA VISTA, Fla. - The winter meetings got busy yesterday with a three-team trade that sent slugger Mark Trumbo to Arizona, and Oakland dealt pitcher Brett Anderson to Colorado.

Halfway through the 4-day swap session, the dais at the Dolphin Hotel near Walt Disney World has been used for three announcements involving player transactions - triple the total of last year's inert meetings in Nashville, Tenn.

In the big deal of the day, the Chicago White Sox acquired outfielder Adam Eaton from Arizona for lefthander Hector Santiago, and the Diamondbacks then sent Santiago and lefthander Tyler Skaggs to the Angels for Trumbo. Arizona also will receive a player to be named or cash from each of the other teams.

"It's nice when you're able to have three clubs up here all feeling good about things," White Sox general manager Rick Hahn said.

Arizona GM Kevin Towers was interested in another of Hahn's players: pitcher Chris Sale. But Chicago doesn't appear interested in dealing the 24-year-old lefthander.

"We would have talked about Mr. Sale," Towers said. "I imagine we might have been doing something directly. But I still can't get him to budge there."

Trumbo, 27, hit .234 with 34 homers and 100 RBI this year, largely playing first base because Albert Pujols was hurt.

After finishing last in the AL Central with their worst record since 1970 at 63-99, the White Sox' Hahn is counting on Eaton to provide a spark. "We lacked a little bit of energy and a little edge," Hahn said. "This is a dirtbag baseball player. This is a guy who has been described to me by someone at this table with words I can't use."

Oakland, the two-time defending AL West champion, received lefty Drew Pomeranz and minor league righthander Chris Jensen from the Rockies for Anderson. The A's also included cash to cover part of the salary of the lefthander, who is due $8 million next season.

"We had a lot of starting pitching, and in the acquisition of Pomeranz, it allows us to turn back the clock a little with another very talented lefthander," said A's GM Billy Beane. "Brett's been with us for several years, and someone obviously with that kind of talent we think very highly of, but with the amount of guys we have, we knew we could use that to get younger guys with less service time, and that was attractive."

Some bigger names were being shopped, with Tampa Bay discussing offers for 2012 AL Cy Young Award winner David Price and the Los Angeles Dodgers listening to those interested in outfielder Matt Kemp.

Among free agents, Detroit closed in on an agreement with outfielder Rajai Davis for a 2-year contract worth $9 million to $10 million, a source told the Associated Press.

It remained unclear whether Japanese star pitcher Masahiro Tanaka will be made available to Major League Baseball teams. Rakuten Eagles president Yozo Tachibana said no decision had been made: "I don't know if he wants to do it."
