Perfect Game clocked Reagan in June 2012 with a max velocity of 89 at one of their tournaments. This was toward the end of his recruiting cycle, so the late velocity bump makes sense.
Tall guys with long limbs take big jumps in velocity when they figure out how to leverage height and long limbs. Who knows why pro scouts were not more interested.
