Pence will play when he returns (if he does return).
Byrd is the best pure power bat on the roster.
Aoki has been the best leadoff hitter all year but is bad defensively.
Pagan is more dynamic than Aoki but hasn't hit as well this year.
Blanco is the best defensive player and has had a hot bat of late.

I guess I'd go with Pence RF, Byrd LF, and Pagan CF if Pagan is really healthy. But I am far from sure on this one. At least we'll have a bench for the first time all year.
