20. LHP, Luis Merejo: The 18-year old Dominican southpaw doesn't have plus arm strength but what he does have is the pitch-ability of a seasoned big league veteran. He's very small, standing just 6-foot and weighing 170 pounds soaking wet, but he can paint his 88 mph big league average fastball in all four quadrants of the plate and mix in an above average big league curveball with long-term plus potential and an average changeup. The smaller size limits his ceiling but few can match his ability to keep hitters off-balance, especially at his age.
19. RHP, Andry Ubiera: This 19-year old Dominican right-hander is better equipped stuff-wise that Merejo right now, boasting a plus fastball that already sits 92-93 mph and tops out at 95 mph, and also showcases an above average big league curveball with long-term plus potential. The changeup is not nearly as developed, however, and the pitch-ability, while solid at the current time, does grade a notch below Merejo's. However, he shows an advanced feel for throwing strikes and his frame could allow for even a bit more power to develop in the coming years.
18. RHP, Juan Jaime: He's borderline too old to be considered a "real prospect" at this point after turning 25 years old late last season. However, the former Washington Nationals prospect missed two full seasons in 2010 and 2011 recovering from Tommy John surgery and he proved the stuff came back last year with Lynchburg. He's back to throwing in the mid-90s and showcases a plus breaking ball, and he struck out 73 batters in just 51.1 innings last season. Now a member of the 40-man roster, he could begin to move quickly and should not be forgotten by pundits.
17. RHP, Navery Moore: The 14th round pick out of Vanderbilt University in 2011 has all of the signs of a long-term 'sleeper'; late-round selection, rather high signing bonus [$400,000], electric arm [92-96 mph], and a checkered injury history in his younger days. The former college closer transitioned to the starting role in his debut season last year and did quite well. He still has to get better command of his pitches and bump his breaking ball up into the plus range, but there's a lot of long-term potential here.
16. 3B, Kyle Kubitza: Like Moore, this third round pick in the 2011 draft has all the makings of a big-time 'sleeper' prospect. He has great size, above average speed, great plate patience, a good glove with a strong arm, and average power potential from the left side that could develop into the above average vicinity should he continue to get stronger. He still strikes out way too much but that's more of a byproduct of being overly patient sometimes. Should he learn to balance his patience and aggressiveness, he could really begin to click.
