Cubs Trade Izturis, Call Up Fox

The Cubs traded Cesar Izturis to the Pirates for a player to be named later and called up AA outfielder/firstbaseman/catcher Jake Fox, who is having a monster year. At West Tennessee Fox is hitting .284 with 18 hr's and 60 rbi. He's a righthanded bat who caught almost exclusively until this season when he started playing the corner outfield spots and firstbase.

I don't know why the Pirates would want Izturis unless they have a deal to dump Jack Wilson in place with another team.
