Rosenthal On Upton, Soriano, Olt, Porter

Highlights from the latest edition of Full Count from Ken Rosenthal of FOX Sports..

• At the age of 28, B.J. Upton will be the youngest outfielder on the open market this winter.  Rosenthal believes that Upton figures to land a deal of at least five years and virtually every NL East team could pursue him.  The Marlins in particular could show strong interest as Dan Jennings was the Rays' scouting director when they drafted him in 2002.  Earlier today, Jerry Crasnick of ESPN.com checked in with four MLB execs who had varied opinions on what kind of deal Upton will get this offseason.
• Rafael Soriano could opt-out of his three-year, $35MM deal at the end of this season in pursuit of a larger deal, but that might not be a wise choice.  That would call for Soriano to forfeit his $14MM salary in 2013 and the Yankees would definitely make him a qualifying offer (around $13MM) that would require a team to give up draft pick compensation to sign him.  Historically, that has hurt the value of free agent relievers.
• The Rangers had little interest in parting with Mike Olt at the deadline but some rival execs think that they'll be more willing to move him this offseason.  While the Rangers have Josh Hamilton and Mike Napoli as free agents and may like Olt to be a part of their offensive core going forward, he could have tremendous value as many teams are in search of a strong third base option. 
• Don't be surprised if the Marlins talk to Nationals third base coach Bo Porter again in the event that they fire Ozzie Guillen.  Earlier this week, the Astros met with Porter, making him the first person to interview for the managerial vacancy.
