This was our first look at 2028 SS/RHP Thejan Gunatilake, a two-way prospect out of the Team Ontario Astros program. The 5-foot-11, 140-pound right-handed hitter was able to generate a peak exit velocity of 81.5mph and was up to 73mph from the shortstop position. On the mound, the right-hander sat 70-72mph, along with a curveball at 63-64mph, slider at 63-65mph and changeup at 67mph. Still plenty of maturation to come which will see his overall game and numbers trend north.
