Recently, ESPN's Kiley McDaniel ranked Meyer as the No. 4 prospect in baseball, behind Los Angeles Dodgers pitcher Roki Sasaki, Red Sox outfielder Roman Anthony and Minnesota Twins outfielder Walker Jenkins. In his breakdown, McDaniel compared Meyer to a "lankier, lefty-hitting Willy Adames if it all clicks."

Once the number-four pick in the 2021 Major League Baseball Draft, Mayer held the consensus top spot on Red Sox prospect lists for the first two years of his minor-league career.
