In the final year of his six-year, $100 million deal, Lee has no doubt lost a step but is still a solid run producer and is off to a nice .300 BA, 4 HR, 21 RBI start.
He is due $18.5 million this season and can veto trades to 14 different teams, so there are no doubt some sticking points, but with the Astros expected to be out of things by July they'll likely do whatever they can to move him.
Best Fit: St. Louis Cardinals
The Cardinals have not been shy about giving aging veterans a chance, evidenced by Lance Berkman and Rafael Furcal last season, and with the aforementioned Berkman recently hitting the DL with a torn meniscus, the Cardinals could be in the market for a short-term replacement at first base.
Prospect Matt Adams will get every chance to win and hold the job, but if they don't feel comfortable heading to the stretch run with him, Lee would make a lot of sense.
