Mariners signed SS Felnin Celesten to a minor league contract.
The deal, which also includes a $4.7 million signing bonus, is now official. The second-ranked international prospect in the signing class, according to MLB Pipeline, Celesten has showcased loud tools and has the chance to be a five-tool player. The 17-year-old is a switch hitter, with more raw power from the left side, and has improved greatly over the past year. His athleticism should keep him at shortstop for the foreseeable future. Dynasty and keeper league managers should keep their eye on this interesting prospect.
