Sonny Bill proves ringmaster

World Cup-winning rugby star Sonny Bill Williams won the New Zealand heavyweight title with a first-round knockout of Clarence Tillman.

Williams, who played the final four minutes of the All Blacks’ victory over France in October, beat veteran Tillman with a second of round one remaining.

The win means Williams has won all five of his professional bouts, three of them by way of knockout. The 26-year-old gave away 44lb in weight to his American opponent.
