First you have Willingham, a talented 30-year old outfielder who never gets any national attention due to the fact that the only two teams he has ever played for are the Marlins and Nationals. But despite playing for the hapless Nationals last season, Willingham put up a .260/.367/.496 line with 24 homers and 61 RBI while constantly playing hard on every play. This is just the type of player that the Seattle Mariners, San Francisco Giants and Atlanta Braves are in the market for. The only question now is whether or not the Nationals are interested in moving him.
On the other hand, the cash-strapped Rangers look to be freeing up some money this off season by possibly moving their ace Kevin Millwood. Millwood had a strong season posting a 13-10 record, 3.67 ERA and 123 strikeouts last season. Thoughts are the Rangers would like to give themselves a little extra money to try to bring in free agent starting pitcher John Lackey to head up their rotation. One team believed to have inquired about the veteran righty was the Milwaukee Brewers who themselves are looking to bolster their rotation.
At this point these rumors are in early stages so it will be interesting to see if anything develops.
[Update 11/30/09 @ 7:32 PM: The Baltimore Orioles have apparently inquired about Kevin Millwood to help bolster their rotation. This would help give the Rangers salary space to go after Lackey as mentioned above or possibly slugger Jermaine Dye.]
