With their third round pick (98th overall), the Seattle Mariners drafted right-handed pitcher Edwin Diaz out of Caguas Military Academy in Puerto Rico.
At 6-2, 160 pounds, he's awfully thin, but still growing into his body. Obviously, the Mariners believe its a frame they can add muscle too, which should also add to his velocity.
Baseball America's Jim Callis mentioned on the draft broadcast that Diaz hit 97 mph with his fastball.
