9. Sam Coonrod

Drafted out of Southern Illinois in the fifth round of 2014's draft, Sam Coonrod emerged onto the top prospect scene in 2015 with breakout numbers for Class-A Augusta. You'll notice a bit of uniqueness to his delivery, beginning a bit slower and then exploding off the mound toward hitters. This makes his mid-90s fastball, with some sink, appear quicker, which he then counters with an above-average slider than breaks hard almost straight down. He continues to develop his changeup — a pitch that may ultimately decide whether he stays in the rotation or moves to the pen. In 2017, Coonrod has improved with higher strikeout rates and lower walk rates.

10. Joan Gregorio

Joan Gregorio has put on some weight since his Augusta GreenJackets' days, now a grand total of 80 pounds since 2011, and that's a good thing considering the man is 6'7". His height and length definitely create a steeper angle in general, though he offsets it with a lower, more 3/4 arm angle. Still, 6'7" coming at you at 90-94 with good sink is nice. His slider used to be slurvy, but has now developed into a remarkable weapon. The pitch is a straight-downer, much like vintage Lincecum. The changeup looks good, too, but is not utilized as much as it could be. Like many starting pitching prospects, the development of a consistent third pitch will determine whether he reaches the bigs as a rotation or bullpen arm. Gregorio will miss the remainder of the season after testing positive for Stanozolol.

11. Reyes Moronta

This stocky Dominican right-hander got a look in the Northwest League as a 20-year-old in 2013 and struggled. He was demoted back to the Arizona League for 2014, and in the next three seasons, he struck out 188 batters in 128 innings. He had a breakout year in 2016 in the California League, especially from May 4 on, where he allowed just under one hit per two innings and gave up only nine extra-base hits over a 50-game stretch. He's been a lethal late-inning threat with his explosive mid-to-upper 90s (and now even 100s) fastball and mid-80s slider, but will get tested in the upper minors as more experienced hitters face what has been at times a below-average command pitcher.

12. Aramis Garcia

San Francisco had Buster Posey and Andrew Susac, and yet they still snagged Aramis Garcia in 2014's second round. Garcia struggled in his debut, splitting time between Arizona and Salem-Keizer, and improved a bit in 2015. He clubbed 15 home runs and 15 doubles, slugging .467 for the GreenJackets. Drafted out of Florida International as an offensive-upsided catcher, he showed good plate discipline and tracking of pitches. It has been his backstop improvement and impressive pop times around and under two seconds from behind the dish that have shifted people's feelings regarding Garcia's best asset. Backup catcher is seemingly his projection, unless he can pump up his offensive prowess over the next few years. Halfway through 2017, returning from facial fractures suffered last year, Garcia has posted one of the highest ISO slugging percentages in the system.
