I'd rather have Desmond bat in the 2 hole as well, but for arguments sake I wonder what pitchers he has faced while batting 2nd compared to 6th or 7th because that could also contribute. I also wonder if Riggleman has Kennedy batting 2nd because of the R/L aspect.
i think Desmond in the 2 hole is the lefty line-up so we would need his splits vs lefties as well to fully judge.
