This is not news to any boxing fan, but the article is worth the read.
Liston just quit before the 7th. Claimed a shoulder injury. It was bullshit.
While Liston was dominating in the very early rounds, by round 6 he couldn't keep Ali's glove off his face. Probably 20 good hits by Ali in round 6 alone. None serious, but all hard. When you get hit in the same eye that many times with hard jabs, it's hard not to say 'what the fuck!', and then, 'fuck this.'
Pick up a 22:00 for the middle of the fifth when it starts to get obvious that Liston is way outclassed.
I think Liston would have lost fix or no fix, in the end. But who can say. In the rounds prior, Liston was focusing on hard body shots; damaging to Ali to be sure, but there's no chance to accidentally knock out the guy you're supposed to lose to.
