Impact The No. 31 overall pick in 2021, Mack hadn't made much noise as a prospect prior to this season. He was quickly promoted from High-A Beloit after hitting .347 with two home runs and as many walks (11) as strikeouts in 13 games, and now he's up to 24 homers on the season in 122 games across the two levels. The 21-year-old lefty-hitting backstop has been 28 percent better than the average Southern League hitter, which is a very strong mark for an age-appropriate catching prospect. Mack has as good a shot as anyone at being Miami's catcher of the future, and he could be a 20-plus homer option at the position during his peak MLB seasons.
