“Roman Anthony is a nonstarter, but maybe Marcelo Mayer? Trevor Story is still under contract for two more years, after all,” Schoenfield wrote. “With Mayer, the Marlins could shift Xavier Edwards to second base. If not Mayer, Arias and Cespedes are high-upside young infielders in Single-A ball (Arias is off to a terrific start).”

Trading Mayer should be a no-go for the Red Sox. The star shortstop prospect should be as untouchable as a prospect gets this season.

Boston has Trevor Story at shortstop right now, but he’s getting older and has struggled with injuries in the past. The clear shortstop of the future is Mayer.

Still, a trade for Alcántara isn’t out of the picture for the Red Sox if they’re willing to part ways with a big leaguer like Ceddanne Rafaela.
