The Boston Red Sox have an MLB-ready prospect in Marcelo Mayer, but what position will he play once he's promoted to The Show?

It isn't a matter of if, but of when, for the Boston Red Sox to call up Marcelo Mayer and Roman Anthony. Whether Mayer or Anthony is the better player depends on who you ask. However, while that doesn't have to be an argument,

As an outfielder, Anthony faces a logjam for everyday playing time as Jarren Duran, Ceddanne Rafaela, Wilyer Abreau and Rob Refsnyder split time, with Masataka Yoshida hoping to return soon from an injury. And at a shortstop, Mayer would have to compete with highly paid veteran Trevor Story for playing time.
