Abrams is going at the deadline. 2.5 years of control with his typical hot start (+hopefully a little improvement) should net something significant.
I'd look to the Pirates and Yankees. Pirates should be looking to maximize their window with griffin, skenes, and the rest of their rotation while it's cheap. They need bats.
Yankees have more money at their disposal, but their offense is lagging behind their pitching.
NYY: Lagrange, Kilby, Hess
PIT: Hernandez, Florentino, and kelly/dotel
