The South Atlantic League recently named the players that would be attending its All-Star Game and four Miami Marlins prospects were included in the list. Left-handed pitcher Ben Holmes, first baseman Josh Naylor, right-handed pitcher C.J. Robinson, and outfielder Isael Soto, all playing for the Greensboro Grasshoppers, were named to the All-Star team.

Ben Holmes is a 24-year-old lefty who has been in the Marlins system since 2014. He was working as a starter up until last year, but has been used exclusively as a reliever this season. It’s gone well so far, as Holmes has a 5-0 record, 2 saves, and a 1.36 ERA. He’s also posted an 8.35 K/9. His numbers look good, but he’s benefited from quite a bit of luck, as his .184 BABIP-against and 93.9% left on base rate are both sure to normalize. Still, he’s put together a good season so far and is deserving of the All-Star nod.

Josh Naylor is the number one position player prospect in the Marlins organization. He was the team’s first round pick in last year’s draft at number twelve overall. In 25 games in 2015, his first taste of professional baseball, Naylor slashed an impressive .327/.352/.418. This season, in 52 games, he’s at .262/.330/.451 with 7 home runs and 36 RBIs to go with 8 stolen bases. He was highly touted as a power hitter, but the 18-year-old is still growing into his body, so the hope is that the power will come.

C.J. Robinson is a 23-year-old right-handed reliever who has been with the Marlins organization since 2013. He’s been strictly a reliever in professional baseball, logging just 1 start among his 113 career appearances. This season, he’s 1-0 with 9 saves and a 1.66 ERA. He’s put up 9.97 K/9 and only 1.66 BB/9. Like Holmes above, the numbers are impressive, but not sustainable. He’s allowed just a .192 BABIP and is pitching to a 3.06 FIP. That’s still good, but not quite as amazing as his raw numbers suggest.

Outfielder Isael Soto is a 19-year-old who has been with the Fish since 2014. This year, he’s slashing .242/.314/.405 with 4 home runs and 20 RBIs. The young Dominican is obviously young for the league and still has a bit of upside, but he isn’t a top prospect that the Marlins are counting on like Naylor.
