From the BA Florida State League chat:

Deywane (Memphis): What happened to Neftali Soto, is he still a prospect?

J.J. Cooper: Still a prospect, but less of one then he was a year ago. He has good hand-eye coordination and plus power but his lack of first-step quickness means he's not a third baseman long term. And some opposing managers and scouts were not impressed with the effort he put out. I wouldn't be shocked to see the Reds try him at catcher where he may profile better
