Ahh, my mistake. My guess is that as of right now, the best case scenario is that Hassell develops quickly this season and makes AAA by mid-season. After that he makes a September call up, and hopefully by that point, if Robles had a decent for him year (I've passed on thinking he will put it all together) that he can be flipped at the deadline.
I think a slightly better case might be an August call up after Robles is dealt / waived.
