Meh, I agree with him. Nastrini doesn't profile as a "play games with service time kind of guy." And besides, it doesn't matter because if he does become a star we wouldn't be keeping him that long anyways.
The issue with it to me is, as its been said a million times already, he hasn't really earned it. And no, I don't think 14 innings in spring training means a guy who has 4 AAA starts has earned an MLB rotation spot.
I would really hate to see him get bombed in his first couple starts and then sent packing, probably not the best for a kids confidence.
