Too Many Pitchers?

With the promotion of Ian Kennedy, the Yankees now have a thirteen man bullpen (including the injured David Robertson.)

I know this usually isn't a problem, but do the Yankees have too many pitchers? With Alfredo Aceves, Jon Albaladejo, Ian Kennedy, Sergio Mitre, and Josh Towers all available as long relievers...can't they let one of them go?

My solution is once again to DFA Sergio Mitre. This time I would like the Yankees to promote either Kevin Russo, or Austin Jackson.

Both are just sitting at home right now, when they could be getting a valuable MLB pennant race experience. Personally, I prefer Russo, only because they are more in need of infielders than outfielders.

Mitre is basically useless right now. Aceves has not pitched since September 14th, Kennedy needs work, and Towers has not pitched since September 12th.

They can handle losing Mitre.
