Braves Rumors: Soriano, Gonzalez, Hudson

David O'Brien of the Atlanta Journal-Constitution talked to Braves GM Frank Wren yesterday.  Hot stove highlights:

• Wren considers the Braves' biggest needs to be the bullpen and the offense.
• O'Brien is certain the Braves won't try to re-sign both Rafael Soriano and Mike Gonzalez.  O'Brien explains why it's in the Braves' best interest to stay tight-lipped about possible arbitration offers for any Type A or B free agents (Soriano and Gonzalez both project as Type As).
• O'Brien guesses the Braves will try to work out a multiyear extension with Tim Hudson at less than $10MM per year.  Decisions on Hudson's $12MM mutual option within five days of the conclusion of the World Series.
• Wren implied Martin Prado will enter Spring Training as the Braves' starting second baseman.  We talked earlier this month about Kelly Johnson as a trade candidate.
• As you learned from Baseball America's Matt Eddy a week ago, righties Jorge Campillo, Buddy Carlyle, and Vladimir Nunez were granted free agency.  Wren says the Braves still need to make decisions on whether to attempt to re-sign any of them.
