Costello died Wednesday at a hospital in his hometown, Kingston, N.Y., longtime friend Joe LaLima said Thursday. Costello was 40-2 over a 20-year career that began in 1979. He won the WBC light welterweight championship in 1984 with a 10th-round technical knockout of Bruce Curry, then defended the title three times over the next year. Costello lost the title to "Lightning" Lonnie Smith in an eighth-round technical knockout in 1985. His only other loss as a pro came to Alexis Arguello in 1986.
