MADE IT TO THE END
Five world champs who retired without a loss
1 JIMMY BARRY, 58-0-10
Active from January 1891 until September 1899. Won world title bouts at 100lbs, 105lbs, 108lbs and 110lbs, and drew in a fight for a world championship at 115lbs. The Irish-american was recognised as world bantamweight champion from 1894 to 1899. Drew his last eight contests.
2 RICARDO LOPEZ, 51-0-1
The Mexican competed from January 1985 until September 2001. Turned pro at 18 and won WBC, WBA and WBO strawweight and IBF light-flyweight titles. Won his first 47 fights. Was 25-0-1 in 26 world title bouts.
3 FLOYD MAYWEATHER, 50-0
Fought from October 1996 until August 2017, cementing his status as an all-time great along the way. The American earned super-feather (WBC), lightweight (WBC), super-lightweight (WBC), welterweight (WBC, WBA, IBF and WBO) and super-welter (WBC and WBA) titles.
4 ROCKY MARCIANO, 49-0
Marciano was a professional from March 1947 until September 1955. He scored 43 wins inside the distance, and made six heavyweight title defences. Anyone who questions the American’s credentials should try mixing it with Jersey Joe Walcott, Ezzard Charles and Archie Moore.
5 JOE CALZAGHE, 46-0
In action from October 1993 until November 2008. The Welsh legend picked up the WBC, WBA, IBF and WBO super-middleweight titles. He made 21 successful defences of the WBO crown, and is the longest-reigning supermiddleweight champion, having held the belt for over 10 years.
