Cramped at shortstop?

I have Miguel Tejada (acquired recently through a trade), Mike Aviles, and Yunil Escobar. I have 2 aces on my pitching staff in Tim Lince and Cole Hamels. After them I have Armando Gallaraga, Jair Jurrgens, Greg Smith, Fransico Liriano, and Chris Young. Closers consist of Mariano Riviera, Solomon Torres, and Manny Corpas. Even if I could trade Yunil or Mike for a CL, what "TIER" are we looking at here? Obviously not a K-Rod type.
