R.J. Anderson from Fangraphs had this to say about Derrek Lee's 2009 season. Derrek Lee posted some great numbers which makes his 2008 season (where he hit into 27 double-plays) seem like an anomaly.
DLee becomes a free agent at the end of 2010. He'll also be 35. So should the Cubs move him while he's worth something?
Personally, I would like the Cubs to move him. And now might be the best time because his value might not ever be as high as it is right now. I'll miss him. But players come and go...
...and that's why I never buy jerseys with their names on them.
