Ever since he was drafted two summers ago, Marcelo Mayer has been the big name in the Red Sox farm system. He hasn’t always been the clear-cut, consensus top prospect in that time, as, when he first debuted, many evaluators kept Triston Casas in the number one slot with Mayer just behind him. But that was merely the product of extreme prudence. Mayer was the consensus best player in the entire 2021 draft, a sweet-swinging shortstop with a surprisingly high floor for a high schooler and the ceiling of a star. From a pedigree and talent standpoint, he represented the most enticing Red Sox prospect since Andrew Benintendi.
