Majewski: good, maybe a wash for Wagner. Bray: decent prospect, ceiling is probably Majewski. Clayton: we all know that he's not Felipe Lopez, even back before he starting decling. Harris: probably roster filler; his ceiling is Clayton-ish. Thompson: the Nats #7 prospect...in 2004. I don't know much about him.
I don't really understand it from the Reds point of view. Majewski might help shore up their bullpen; maybe they think Bray can help this year, too. Maybe they're convinced Clayton's glove cancels out Clayton's bat, and that Felipe Lopez wasn't their future at short. But I suspect that any short-term gains Cinci reaps from the relief upgrade they lose at short.
