11. Kameron Misner
Missouri Tigers, NCAA Division I
Kameron Misner was chosen in the competitive balance round of the 2019 draft, 33rd overall by the Miami Marlins. An outfielder from the University of Missouri, he has racked up a collegiate slashline of .302/.425/.491 with 21 homers and 91 RBI, along with 50 stolen bases. In his final season, just completed, he drew nearly as many walks (54) as he struck out (56).
12. Brian Miller
Miami’s competitive balance pick in 2017, Tar Heel Miller is fast enough to play any of the outfield positions, while boasting the versatility to fill in at any of the infield spots if called on. In parts of three minor league seasons with the Miami Marlins, he has slashed .297/.348/.371 across three levels. He’s also stolen 72 bases in 98 tries.
Miller is seasoned enough to join the Miami Marlins roster today if needed, however you’d be far more likely to find him with the parent club sometime late next season.
According to Baseball America, Miller will never be a power hitter:
"Considered by many to be a 70-grade runner, Miller led all Marlins minor leaguers with 40 stolen bases in 2018. His speed is also an asset in the outfield, where he has the potential to be an average center fielder with an average arm. Miller has hit just one home run in 185 minor league games, and he’ll likely never have much more than fringe-average power. His line-drive swing, advanced contact skills and speed give him a chance to be a plus hitter, however, and he’s a career .304 hitter with a strikeout rate below 13 percent in the minors."
13. Jordan Holloway
Jordan Holloway has always been sort of an enigma. We weren’t sure what the Miami Marlins had in him exactly. Flashes of brilliance punctuated by lengthy stays on the club injured list. Not this season.
Holloway has started 11 games for Jupiter this season, and has allowed 29 base hits in 46 innings pitched. He’s also struck out 51 batters, and has a 2-4 record with a 3.72 ERA. Since getting chosen in the 20th round back in 2014, Holloway has never pitched more than 68 innings, in 2015 with the Batavia Muckdogs. He’s got a great chance to surpass that easily.
14. Chris Vallimont
Clinton LumberKings, Single-A Midwest League
Although Vallimont remains unranked by all major prospect listings, he’s done enough with the LumberKings this year to start the Midwest League All Star game. He’s 4-4 with a 2.99 ERA over 13 stats, with 80 K’s in 69 1/3 innings and a 1.07 WHIP.
A 6’5″ right-hander out of Mercyhurst College, Vallimont was the Miami Marlins fifth round choice in 2018. A better than average fastball that hits 96 on the gun is complemented by what can only be called a wipeout slider. Look for him to join the Hammerheads pretty soon.
15. Braxton Garrett
Big things were expected very quickly after Braxton Garrett was chosen by the Miami Marlins with the seventh overall pick in 2016. After not appearing in the playing season after his selection, he had a solid start to his minor league career in 2017. He struck out 16 in 15 1/3 innings for the Grasshoppers, with a 2.93 ERA. Tommy John surgery took him out of action until the 2018 campaign.
"In addition to his potentially plus curveball, Garrett has a low-90s fastball that was reportedly in the 92-93 mph range in the Marlins’ fall instructional league once he returned to the mound post-surgery. Known for having at least above-average command coming into the 2016 draft, Garrett also has a third-pitch changeup that’s shown late fading life in the past. – Baseball America"
Garrett has picked up where he left off. He’s whiffed 77 in 61 innings at High-A this year, and gone 3-3 with a 3.10 ERA.
