While boating with a friend, Castillo decided to go swimming near his Arizona home. His friend that accompanied him on the boat ride frantically called for police when Castillo did not resurface.
His major league career started with his 1991 debut with the Cubs, for whom he pitched seven seasons before being traded to the Colorado Rockies during the 1997 season. He gained notoriety for while pitching in Chicago for coming one out short of pitching a no-hitter on September, 25, 1995 against the St. Louis Cardinals, when Bernard Gilkey broke up the bid with two outs in the 9th inning on a 2-2 count.
He also pitched for the Detroit Tigers, Toronto Blue Jays, and Florida Marlins, last seeing action in the majors in 2005. He continued to pitch in the minor leagues and independent ball until 2008. After his playing career ended, he was a coach for the Cubs in their minor league system.
