Found this on a Yankee site, don't know how accurate:
49- Gilmael Troya β RHP β 18 β 6β0 / 178
2015 Stats (Rk) β 9 Games β 36.0 IP β 2.25 ERA β 39 K / 14 BB
Report: Ascending prospect. Pitched really well in the GCL which is usually hitter friendly. Still learning how to pitch he has a strong fastball (91-94) β curveball combo going. Improving command and developing another pitch are on his to-do list for next season.
Moved to the pen last year and posted great numbers, may have had an uptick in velocity in that role.
