If we DFA an infielder, I'd want an infielder added, too.
We still have only Dalbec backing up 1B.
We still have just Dalbec & Reyes backing up 3B.
We have nobody I trust backing up Rafaela at SS.
Once Grissom returns, we'll have plenty of back-up 2Bmen: Reyes, Valdez, DHam and maybe Romy when he returns.
(I forgot to add DHam to my DFA list.)
