I think they looked at it as a (relatively) free look at Cespedes. He has a spinnable contract, and serious talent. If you look at how little they gave up, the move makes sense. (2 months of control of Lester and Gomes, neither which they needed) Now, I was critical of the deal at the time because I was not sure they optimized Lester's value. However, when you saw how little the Rays got back for David Price, I think it was much more of a buyer's market than it seemed.
