I think so, yes. He would need exposure to waivers if sent back down.
My whole deal with him is if not now, when? He isn't going to be a long term option for us, so his opportunity to help the big league club is now. Otherwise we are saying he is a "break glass in case of emergency" guy for us... which is fine if true but I feel we can utilize the asset better?
If he comes up and shows well, he has created a small trade value that could be capitalized upon if we need to send him back down. If he comes up and doesn't show well, he either clears waivers ala Greg Jones/Luis Matos or we lose him to a waiver claim - in which case he wasn't going to get another call up in that instance anyway and we will need a spot or two available for promotions to AAA as it is.
The only reason to hold him full season without an early season opportunity is in case we suffer multiple injuries late in the year ... but by then both Jett and Pratt will be the next in line for a RH hitting infield/outfield option to be brought up.
He is hitting well and we could use another RH bat ... we haven't hit LHP well at all this year. I feel like he can help and his opportunity to help is now IMHO.
