Cal Coaches On Sebastian Crampton
“Sebastian is a very gifted player. He has exceptional length off the tee, and what’s even more impressive is that he has another gear if he wants to add an extra 10-15 yards with his driver. His iron play is very sharp and when he’s on with his irons, birdies can come in bunches. In addition to all his physical abilities, he’s exceptionally smart in the game with tremendous course management.”
