05/29/2021 - 2021 BF National Florida Showcase Sebastian had an extremely impressive outing at the Baseball Factory Florida Showcase, pounding the zone with a quality 3-pitch mix. Everything he threw had life to it including his fastball that was up to 93 mph. He used his 2-plane breaking ball as a swing-and-miss pitch and added in a change that had good arm speed and some late tumble. Sebastian worked ahead and challenged hitters using a clean, athletic delivery to repeat well. The arrow is pointing up for this young RHP prospect, whose big, strong frame and stuff remind us some of another former south Florida hurler, Alek Manoah.
