Paulino is way too far away to be protected. Wikelman is probably too far away to be protected this time. Would a team be likely to select Wikelman after 17 innings in High A? His Low A numbers weren't popping off the stat sheet. Murphy doesn't have a long track record of success and struggled in AAA this season. He may not be protected either.
Personally, I think it's more likely that Ward is protected than any of the guys you mentioned. He's much closer in proximity to the bigs so he's easier to stash and he's performed well since coming back from TJS.
