The Boston Red Sox chose Marcelo Mayer, a shortstop from Eastlake High School, with the 4th overall selection.
Mayer, perhaps the finest five-tool prep shortstop in a crop that is overflowing with them, has stood out from the start. The left-handed batter, who is just 18 years old, is 6-foot-3 and has the body and agility to play in the major leagues.
Mayer’s batting has been given a 60 on the conventional 20-80 scouting scale by MLB Pipeline. When you consider that just one other player in this year’s draft class received a 60, the highest rating given this year, it’s a fantastic ranking. Scouts have remarked on his baseball IQ and how he glides around the field so easily, and how powerful he is defensively as well as offensively. Corey Seager and Carlos Correa have been compared to him because of his excellent balance.
Mayer departed Eastlake High School with a bang, batting.392 with 45 RBIs and 14 home runs before committing to USC his senior year. In his last high school at bat, he also hit a grand slam, which screams dramatic baseball movie scene right there.
Mayer’s greatest area for improvement right now is his baserunning speed, but given enough time to develop and expand, that shouldn’t be a problem for this Swiss Army knife of a draft selection.
Mayer attended a high school that produced five-time All-Star Adrian González and, most recently, Keoni Cavaco, the 13th overall selection in the 2019 MLB Draft.
