Does everyone here realize that Perkins was already under team control through 2016? Am I missing something? Why in the world would the team do this? Closers have short shelf life's, Perkins will be what, 35 in 2017? Why not wait 2 or 3 years and see if he is worth an extension. This is a head scratcher to say the least
My thinking is he is currently grossly under paid for what he does and this is a way to garauntee him more money and give him more security in case his arm does fail him down the line. Both sides take some risk here. Perkins likely could have made more not giving his team a hometown discount and the Twins risk he may be injured beyond repair sometime later in the contract. If both sides agree to those risks it is a win, win.
Forget about trading him now. It won't happen because if he is pitching well the Twins have a great deal and won't want to give that away. If he is pitching poorly no one will want him anyway. He is virtually un-tradeable until later in the contract IMO.
