Updated 27 November 2020, with the defiling of Wanheng Menayothin world record. The crown rightfully goes back to Floyd Mayweather 50-0-0 Floyd Mayweather 49-0-0 Rocky Marciano 46-0-0 Joe Calzaghe 43-0-0 Samson Dutchboy Are there any boxers over 40-0-0 who can move up the list?
Also, Packey McFarland is credited as 70 - 0 by Boxrec, and could possibly be as high as 100 - 0, though there is a loss account, but I don't know how verified it is. He has 5 draws however. https://boxrec.com/en/proboxer/36384
Absolute format W-0-0, no nasty draws, only perfect wining records like Floyd Mayweather, so no Packey, Barry or Ricardo Lopez on this list
Thanks...Zurdo been enriching his W column silently.... Floyd Mayweather....will get him a big $ fight at Cruiser or Bridger ASAP
