19. Cody Hall
RHP | Richmond Flying Squirrels (AA) | 6’4″ | 220 lbs | 2011, 19th round | 27-years old
From MLB.com: "Hall didn't play baseball in his final two seasons of high school, then had a modest career at Baton Rouge CC and Southern before signing for $2,500 as a 19th-round college senior. He has dominated Minor League hitters, recording a 2.31 ERA and averaging 11.5 strikeouts per nine innings in his first four seasons.
Hall mainly attacks hitters with his fastball, which usually sits at 94-96 mph and can reach 98. His ability to refine his slider will determine whether his ceiling is that of a setup man or a middle reliever, and he made strides with his breaking pitch in 2014. It's more notable for its mid-80s velocity than its bite and devolves into more of a slurve at times.
Though he can mix in an occasional changeup, Hall works primarily with his fastball and slider. There's some effort and recoil in his delivery, but it doesn't hamper his ability to throw strikes."
20. Gary Brown
CF | Sacramento River Cats (AAA) | 6’1″ | 190 lbs | 2010, 1st round | 26-years old
From MLB.com: "Brown signed for $1.45 million as the 24th overall pick in the 2010 Draft, and he looked like the Giants' center fielder of the near future when he starred in high Class A in his first full pro season. But he leveled off offensively in Double-A in 2012 and hasn't produced in Triple-A the last two years, and now his outlook is uncertain.
The tools are all still there for Brown to be an everyday center fielder in the big leagues, though it's more realistic to look at him as a fourth outfielder at this point. He still has well above-average speed, which should allow him to hit for average, steal bases and play fine defense. Brown's quick bat gives him some gap power, and he even has average arm strength.
To realize his full potential, Brown will have to make adjustments. First and foremost, he needs to cut down his swing and adopt a more disciplined approach. Brown also needs to refine his basestealing technique, as he gets nabbed more often than he should, and he could improve his routes in center as well."
