MLB in 2023: Top Prospect for All 30 Teams

Boston Red Sox — Marcelo Mayer

Projected ETA: 2024 (No. 9 Overall Prospect)

We talk about toolsy players all the time. Mayer epitomizes that considerably. Hailing from San Diego, he was the National High School Player of the Year as a senior. Boston took him No. 4 overall in the 2021 MLB Draft.

It’s been a bit of a mixed bag for him thus far. He’s been battling with some nagging injuries (though at only 20 years of age, he should be fine). As was his reputation in high school, Mayer’s transition to hitting the baseball on the Minor League level has been smooth. He has power to all fields, and his approach at the plate is truly special. We’ll see if he sticks long-term at shortstop (Mayer is 6-foot-3). At the very least, you’re looking at a professional hitter with some big-time upside. Think Corey Seager with a better glove/arm.
