Miami Marlins: Our 2021 End of Season Top 30 Prospect Rankings
By Matt Melton
8. C Joe Mack
Miami’s Competitive Balance-A pick in the 2021 MLB Draft (No. 31 overall), the Marlins selected Mack out of Williamsville East High School (NY) as one of the top overall catchers available. Debuting in the Marlins organization in mid-August, Mack would appear in 19 games with the FCL Marlins where he posted a .581 OPS with a home run in fairly limited action.
Instantly becoming Miami’s top catching prospect, the 18-year-old is not only a plus-defender behind the plate, but displays some of the best power-potential among any Marlins prospect in his left-handed swing. Mack will likely begin next season with the FCL Marlins or Low-A Jupiter, with a massive breakout season at-the-plate potentially on the horizon.
7. LHP Jake Eder
One of the fastest-rising prospects in all of baseball this season, Eder enjoyable a phenomenal 2021 campaign, all of which was spent in Double-A Pensacola. Making 15 starts with the Blue Wahoos, the left-hander posted a 1.77 ERA with 27 walks and 99 strikeouts, a season which also included a trip to the MLB Futures Game over the All-Star break.
Miami’s 2020 fourth round pick, Eder’s rise this season was one of the best among Marlins’ prospects in recent memory which resulted in an overall Top 100 prospect ranking according to MLB Pipeline. Recently undergoing Tommy John Surgery, Eder will likely be out for all of the 2022 season, with a return in 2023 likely.
