The current difference between No. 84 and No. 91 on a Top 100 prospect list is not significant.
Marcelo Mayer and Ben Williamson offer difficult comparisons as Mayer was a No. 4 overall pick out of high school in 2021 while Williamson was a second-round, No. 57 overall pick in 2023 as a rare four-year college player. In 55 games his senior year at William & Mary, Williamson posted a .390/.513/.662/1.175 line (57 R, 12 HR, 49 RBI, 14 SB, 40 BB, 22 K).
Williamson was rushed to the majors 20 months after the draft with only 150 minor league games under his belt. Mayer debuted 39 days later after 315 games over five seasons in the minors.
Last season Mayer posted 0.2 bWAR (0.4 fWAR) and a wRC+ of 85 in 44 games while Williamson posted 1.3 bWAR (0.4 fWAR) and a wRC+ of 76 in 85 games.
