Gonna need a guy that can consistently get on base to round out the lineup (preferably a left bat).
If Varsho, Chap, Jano, Biggio, KK are in the lineup together (which they will most of the time), chances are there'll be plenty of low scoring games and not a whole lot of getting on base. If any combination of those guys fall in a slump at the same time, this team will struggle mightily to produce runs.
