We've got multiple tweets suggesting the Yanks are shopping their newly acquired Rule 5 pick (and why wouldn't they? you never know who will be willing to make a bad trade).

Otherwise, Arquimedes Caminero is exciting for more than just his name: he'll turn 23 in June, throws high 90s gas with a plus mid 80s slider. He struck out 3/4 of the league but walked the rest.
He's never pitched in AA, so I don't see how he'd stick in NY. The Yanks could trade him to another team willing to keep him on the roster all season.
