Marcelo Mayer was recently identified by MLB Pipeline as the top defensive prospect in the Red Sox’ farm system.
A pure-hitting shortstop out of Eastlake High School in Chula Vista, Calif., Mayer was selected by the Sox with the fourth overall pick in last summer’s draft.
Upon signing with Boston for a lucrative $6.664 million, Mayer was assigned to the rookie-level Florida Complex League Red Sox to begin his professional career. He debuted for the affiliate on August 5 and appeared in a total of 26 games.
In addition to posting a .275/.377/.440 clip (121 wRC+) over that stretch, Mayer also saw all of his playing time on the field come at shortstop. While logging 177 2/3 innings at the position, the 6-foot-3, 188 pounder turned three double plays and committed a team-high 10 errors.
Despite the high number of miscues, there does not seem to be too much concern surrounding Mayer’s defensive abilities considering the fact that last year only served as the 19-year-old’s introductory course to pro ball.
As noted by the MLB Pipeline staff, “the California high school product possesses just fringy speed but makes up for it with a quick first step, and he also displays smooth actions, quick hands and a finely tuned internal clock at shortstop.”
Mayer himself was bothered by the amount of errors he made, as he explained to The Athletic’s Jen McCaffrey last month that improving defensively has “been a focal point of his offseason work.”
With spring fast approaching, Mayer is currently regarded by MLB.com as the top prospect in Boston’s farm system and the No. 9 prospect in all of baseball. The left-handed hitting infielder is projected to start the 2022 minor-league season (also his first full season) at Low-A Salem and is understandably excited for it to get underway.
