The Dallas Morning News mentions everyone's favorite human hummingbird among its rumors about the Rangers' need for a center fielder:
There might be guys available for trade. The Rangers could explore dealing for Philadelphia's Aaron Rowand, but that would probably take something such as Hank Blalock. And new manager Washington has made it clear he wants to work with Blalock.
A more likely trade possibility might be Cincinnati's Ryan Freel. He could be part of a platoon in center and would also replace some of the versatility that the club will lose if Mark DeRosa signs elsewhere, as expected.
I don't think there is there any possibility that the Reds could get enough out of a trade for Ryan Freel. The trade would have to do more than address one of the team's needs; it would have to justify giving up Freel's skill, spark, and popularity. Trading Felipe Lopez and Austin Kearns for middle relievers makes people think you're an idiot. Trading Freel for a middle reliever would make people think you're Satan.
