Re: who's in left?
Dickerson still managed a .378 OBP vRHP last year.
Either Phillips or Rolen should be hitting behind Bruce this year, which is about as much of a threat as you'll get in the Reds lineup, definatley more so than Gomes would be. I don't know if protection is the reason he's been bad vLHP though, and that is the only time Gomes would be behind him.
Fair enough on the last point.
