Nats have 10 players on their 40 man roster in the minors (Maya, Perry, Lannan, Purke, Leon, Marrero, Rendon, Rivero, Brown, and Perez) and 5 players (DeRosa, Desmond, Solano, HRod, and Wang
) on the 15 day DL. One would have to be removed to make room for Garcia. I suppose Wang might be put on the 60 day DL if they decide he's done. Otherwise, perhaps Maya gets removed from the 40 man roster. DeRosa will be kept for depth, I think, but with Lannan and Perry and even Gorzelanny, there's little need for a 4th spot starter.
