When Matt Moore was traded to the San Francisco Giants last year, the Tampa Bay Rays received infielder Matt Duffy along with prospects Lucius Fox and Michael Santos. The trade did not produce anything close to immediate dividends for the Rays, as Duffy was injured shortly after being acquired and Santos did not pitch in their system last season, as he was already on the disabled list.
Fox, however, was expected to make his debut in the Rays system. An exciting prospect, he had struggled to a .207/.305/.277 batting line, showing little extra base power.
