Though Terry Pendleton is not a great hitter, he can provide a little slappy hitting versus lefties, and in a system that heavily rewards defense, a 1 at third base for .67 is a deal to me.
I also think that Jim Presley (a 2 at 3b) with his great clutch hitting is an ideal platoon man for a very reasonable price. Though I have yet to implement it, I think you could pair Presley up with a one of a few guys and get better production overall from them for under $5 than most of the 3B priced over 3B.
