8. LHP Braxton Garrett
2021 Season Stats: 4-3, 4.41 ERA, 1.196 WHIP, 17 BB, 49 K
If Eder isn’t the top southpaw in the Marlins’ system, you could make an excellent argument for Garrett, the Marlins first round pick in the 2016 MLB Draft. Splitting time this season between Triple-A and the big leagues, Garrett has spent a majority of that time in Jacksonville playing with the Jumbo Shrimp.
Through 10 starts so far in Triple-A, the 23-year old left-hander has posted a 4.41 ERA in 51 innings pitched. While Garrett has also posted a 5.17 ERA in 15.2 IP with the big league club this season, the southpaw may receive a full-time big league call-up later on this season depending on what Miami does at the 2021 MLB Trade Deadline.
7. 1B Lewin Diaz
2021 Season Stats: .228 AVG, .304 OBP, .532 SLG, .836 OPS, 14 HR, 36 RBI
Another top prospect that has spent time between Triple-A and the big leagues this season, Diaz could very quickly make his way to the big leagues full-time over the next couple of weeks. Yes, depending on what Miami does over the next two weeks, the Marlins currently No. 6 prospect could become the full-time starter at first base.
Diaz has flashed his big-time power potential so far this season in Jacksonville with 14 HR’s up to this point, and is the no-doubt top first base prospect in the Marlins system. If Diaz keeps driving in runs the way he currently is in Triple-A, the Marlins may have no choice but to call-up the 24-year old slugger.
