The BJ's mlb site has Santos listed on the 40 and 25 man rosters and the roster being full at 40. Maybe ESPN is a bit behind? They'll have to remove someone if they bring Morrow off the 60 day DL. I can see Johnson, Hynes, Hague, Mastroianni as options to be DFA or maybe Johnson or Lawrie transferred to the 60. AA had 3 open spots only to fill them with Hynes, Hague and now Santos. Depends on what AA wants to do. If any of those guys aren't in the plans for next year, and lets face it Hynes, Hague, Mastro don't seem to be since they're depth moves a spot could open. I'm not sure if they could put Wagner on the 60 since they'd have to recall him and place him on the DL which would also cost them more money since it would count towards his MLB service time and they could use the excuse he was hurt in the minors so it doesn't count. I could be wrong.
I'd rather them leave Norris in the minors let him rest up and try winning a spot next year. The Jays are all but out of the race and he's not going to make or break the team. If they want to add him to the roster they can do so in the off season or wait until spring if he wins a spot.
