Yes, but at the end of the day he is just a reliever. You must always be open to changes and to know the true positional value.

AA, Trade dat f***ing bullpen
Stop smoking pot
Relievers for Castellanos/Wong/Polanco is a crazy idea. AA isn't a magician, he's just a fat guy with serious love for the hardthrower relievers.
Rajai has made me change my perception about him. He is a good role player, a very valuable piece for any team, I think will get good contract in free agency (~5M AAV)
