Several have gone past Rocky Marciano’s 49-0 record and finally Floyd Mayweather, Jr. equaled it in 2016. Those who went beyond that would eventually taste defeat. Saturday night Nicaragua’s WBC World super flyweight champion Roman Gonzalez lost after 46 straight wins to Thailand’s Wisaksil Wangek, 41-4-1.

Dariusz “Tiger” Michaelczewski from Poland fighting out of Germany who was the WBO light heavyweight champion got to 48-0 before losing to Julio Cesar Gonzalez, 34-1, taking a split decision in Germany.

Few have shown the bitterness that Larry “The Easton Assassin” Holmes of Easton, PA, did when at 48-0 he was the first heavyweight champion to lose to a light heavyweight champion in Olympic Gold Medalist Michael Spinks, 27-0, in 1985. To this day you never hear Holmes give Spinks any credit. He simply says “Marciano couldn’t wear my jock strap” blaming his loss on Marciano! At a press conference in 2016 he was still saying “I never chased Marciano’s record!” Bullshit. You wonder why Ali nicknamed him “Peanut Head?”

At 49-0 that means no blemishes such as a draw or no contest. A week apart Paul “The Pittsburgh Kid” Spadafora, on November 30, 2013, he lost to Johan Perez, 17-1. He was 48-0-1 when that happened. He won his next and last fight finishing at 49-1-1. The Indonesian Chris “The Dragon” John, was 48-0-3, when on December 6, 2013, lost in his final bout to South Africa’s Simpinwe “V12” Vetyeka, 25-2, along with losing his WBA super featherweight title finishing at 48-1-3.

Mexico’s Ricardo “Finito” Lopez was 47-0 when he was held to a technical draw defending his WBA and WBC minimumweight titles, against Rosendo Alvarez, 24-0-1, of Nicaragua in 1998. In his next fight he defeated Alvarez by a split decision. Lopez would win his next four fights including winning the IBF World light flyweight title and finish at 51-0-1. Mexico’s Luis “Yori Boy” Campas, went beyond 49-0 before losing to Felix “Tito” Trinidad, 23-0, and his IBF welterweight title when he was 56-0 in 1994. He would finish up at 106-17-3.

Going way back in time there was Packey McFarland, who finished up at 70-0-5. He was 36-1-1 with NWS fights of which some historians do not include in the record books. That loss was in 1904 to Dusty Miller, 11-3-2, in McFarland’s ninth fight. Willie “Will o’ the Wisp” Pep, was 62-0, when he lost to Sammy Angott, 69-17-15, in 1943, and ended up with a 229-11-1 record.

Julio Cesar Chavez, Sr, was 87-0 when he drew with Pernell “Sweet Pea” Whitaker in 1993. Then he lost when he was 89-0-1 the following year in 1994 to Frankie “The Surgeon” Randall, 48-2-1. Chavez world finish up with a 107-6-2 record. Joe Calzaghe ended his career at 46-0. Currently there is Thailand’s WBC minimumweight champion Chayaphon Moonsri, who is 45-0.

Born in Mauritania and moved it Italy was Nino LaRocca was 56-0 when he lost to Gilles Elbilia, 22-2, in 1984. LaRocca ended up 74-6. Denmark’s Brian Nielsen was 49-0 when he lost to Dicky Ryan, 47-4, in 1999. He ended up 64-3.

Russia’s WBA heavyweight champion Nicolay Valuev was 46-0 when he lost to Ruslan Chagaev, 22-0-1, in 2007. He ended up 50-2.
