There's no need for it to be. Come September 1 with expanded rosters, you just add a player and Desmond just sits until he's healthy.
That's right. Plus, Desmond has to be nearly ready or Davey wouldn't have taken the risk.
Charlie and Dave were all over it, correctly guessing that Davey didn't really mean for Desmond to bat and that he wanted the Tracy matchup instead. Just a relatively minor chess move.
