Right now the Rays have 43 players on their 40 man roster (three on extended DL, one on inactive list) here they are:
We'll have to free up four spots for those players with Paul, Glover, Velandia, Norton, Stokes, Camp, and Casanova likely on the way out. The notable players we have to protect in the Rule V draft are Fernando Perez, Jason Pridie -- who was a Twins Rule V pick a few years back, he was subsequently returned to the Rays -- and John Jaso.
Of course a number of trades could be made before December, but after those moves the Rays have no room on the 40 man leaving the most likely candidates to be removed: Switzer, Ryu, Johnson, Wilson. One of those slots has to go to Evan Longoria you would think.
One of the most underrated aspects of roster management is the 40 man roster, what should the Rays do with the likes of Wilson / Zobrist? Do they keep Gary Glover around or let someone like Medlock get a shot? Can Riggans hold down the backup catching spot letting the Rays keep three catchers on the 40 man with Jaso playing in Durham?
I'd be interested to know what the general consensus on some of these minor events are.
