Comparing anyone to a Hall of Famer is probably unfair. To do it to a prospect is downright silly.
So, let’s go ahead and do it anyway.
In 1990, Trevor Hoffman was a light hitting 22 year old Shortstop. He hit .212 and was at a crossroad in his career. One of his coaches made a suggestion that he try his hand pitching. The rest is history. Hoffman immediately saw success the next year. He had 20 saves and a 1.89 ERA while playing in the Reds farm system.
Eventually, he landed with the Marlins before heading to the Padres in a controversial deal involving Gary Sheffield.
