wayne mc cullagh stopped arturo gatti in 1 round in the amateurs. Think it was an ireland-canada internationals
Carl Froch fought Jason Booth three times as young amateurs, the first fight was actually Carl's first bout. Booth is now British Super bantam weight (junior feather weight) champion and about to challenge for European and world honours.
Only reason I bring that KO up is because it's one of the most shocking KO shots I've ever seen. If you get a good side angle of the KO you'd see that Johnson's right hand came off like a ****ing rocket, nailed Sanchez on the side of the head, and dropped Augie hard on his right side like a man who's just been shot by a sniper rifle. It's one of those KO's where you ask yourself, "Holy ****! If he dead?!" Augie was out cold for maybe 5 - 7 minutes.
yeh 11 yrs old froch's 1st am bout he stopped booth though then beat him twice more on points very young an small them days.
