Scouting report
Olacio was signed as a 17-year-old for $125,000. Standing 6-foot-7 now, the young lefty has a big frame that was still getting taller even after he signed. After a year in the DSL, Olacio reached the states as an 18-year old splitting time between Bristol (Rk) and Kannapolis (A), but in the reverse order. In both leagues he struck out a good number (8.3 K/9) but had predictable control issues (6.0 BB/9). In 2013 at Kannapolis he was purely a starter, improved his control (3.8 BB/9) but missed a lot fewer bats (5.9 K/9) in 25 starts.  2014 saw the inevitable transition to relief work, where his strikeout numbers were strong (71 K in 70.1 IP), but he got hit hard (84 H) and had more trouble with walks (5.0 BB/9) in AA and A+. In 2015 things got even stranger in terms of his career track, as he had 3 messy outings in Winston-Salem (7 BB in 2.1 IP), was returned to extended ST for coaching, went back to Kannapolis for five outings that seemed not much better, back to W-S again for 17 more relief appearances where he walked nearly a batter an inning, then made a final appearance in Birmingham walking four batters in a single 2-inning outing.

Olacio arrived as a teenager in the US still growing in height, then put on huge amounts of weight (some good, some bad), and really spent a couple years just trying to grow into his body. This is directly related to his delivery inconsistencies, though now at 22 years old he should be more solid at this point than he is. In the AFL in late 2014, a scout referred to his delivery as looking like "three kids on each other's shoulders wearing their dad's trench coat trying to pitch". His fastball can be in the mid-90's, but at other times is much slower. His slider flashes potential but is erratic. While it is unlikely he ever puts it together at this point, he is still recently-turned 22 and it's not impossible he finds enough consistency to get back to prospect status. There is no telling what affiliate he opens with in 2016.


Major League Outlook: Late-inning reliever
