Hernandez was a highly ranked prospect at one point, but both his hitting and fielding took a step back in 2019. He was on their taxi squad last year, so maybe there could be something there.
Rays fans are talking themselves into the deal because they like Springs k/9 and Hernandez was on the 40 man but probably not close enough to MLB to be called up anytime soon.
So Hernandez will have to be put on the Sox 40 man, right?
