GRAND FORKS, N.D. (AP) _ Virgil Hill seeks to defend his WBA light heavyweight title for the 21st time when he meets challenger Louis Delvalle of New York tonight.

The 32-year-old Hill (41-1) is the winningest light heavyweight champion, losing only to Thomas Hearns in 1990.

Hill is hoping to reach super stardom in boxing before retiring. He hopes the Delvalle fight, the first of a four-bout contract with HBO, will give his career that extra push to the big money.

Delvalle (22-0), a former New York City Golden Gloves champion, is competing in his first title fight.

The Grand Forks card also features heavyweight Buster Mathis Jr., who lost by knockout to Mike Tyson last December. Mathis (20-1) will be fighting Obed Sullivan (17-1-1) of Lancaster, Calif.
