Roy Jones Jr. scored a unanimous decision over John Ruiz and claimed the WBA heavyweight title and a piece of boxing history on Saturday.
Jones, considered the best pound-for-pound fighter in boxing, outboxed Ruiz for 12 rounds and became just the second person, to hold both light-heavy and heavyweight belts.
Michael Spinks, who beat Larry Holmes in 1985, was the first.
The victory also gave the 34-year-old Jones a rare hat-trick of titles becoming the first fighter in 106 years to capture middleweight, light-heavy and heavyweight crowns.
Not since Bob Fitzsimmons recorded a 14th round knockout of James "Gentleman Jim" Corbett in 1897 had a former-middleweight beaten a heavyweight champion.
