One that comes to mind is Leroy Jeffery, one fight away from retirement, blowing out a 34-0 Howard Winstone... Knocking him down three times in two rounds. 21 days later Jeffery would once again fight in the UK, dropping a PTS decision to a 19-12 Billy Calvert before retiring for good. To me, Briscoe's half round destruction of Eugene Hart was a shocker after they seemed to lay it all on the line in their first bout, which ended in a draw. Nunn/Kalambay of course. I don't know if that would happened the same way if they had fought 20 times. On the theme of first round shockers, here's one on a much lower level that I always think of. This content is protected How about Chang/Kittikasem II? Or Galaxy/Espinosa.
Marion Wilson clearly deserving the nod against Mercer was a shocker, but that was essentially Mercer in a nut shell.
Pacquiao vs Marquez 4, the fights were all decisions where Marquez was the one on the floor. Many felt Juan won the third fight but no one expected a KO and Manny hadn't been knocked out in a longtime. The brutality of the shot itself was also alarming because during this time most of the pay-per-view main events with Floyd and Manny were often one sided decisions lacking drama Tarver-Jones 2 always springs to mind
Hearns vs Duràn, Duràn had so much momentum while Tommy recently lost his,which adds more shock to the one sided beating. Otherwise it would be Saman Sorjaturong vs Humberto Gonzalez, Saman was nearly stopped at the 6th round,thus he gave his all for the 7th round and stopped Gonzalez who's trying to brawl with him too.
Darren Van Horn managing to beat Lindell Holmes. Holmes was slightly undersized at 168, he only moved up because he was having trouble getting fights at 160, but he was still a good boxer-puncher with an excellent left hook. However, he seemed to take the limited Van Horn lightly, turned in a completely half-assed performance and ended up gassing out from body shots.
Booker T. Word's one round blowout of Olympian Anthony Hembrick, especially after Hembrick's garish and presumptive break-dance routine.
That bout reminds me of evil punching Puerto Rican Jorge Maysonet knocking the much hyped and undefeated Hugh Kearney out in his backyard... Kearney was down and out 10 seconds into the fight and the ref didn't even start a count despite it being Kearney's backyard. First punch of the fight and everything if I'm remembering correctly.
Michael Bentt only had 13 career bouts in his career. Tommy Morrison fought him as a tuneup before his 8 million dollar payday against Lennox Lewis and Morrison got knocked out in the first round
Bentt had some raw talent and could punch a bit with speed. An 8-8 Puritty knocked Morrison down twice and almost had him out of there over 10 rounds. Morrison's durability was never his strong suit.
