Round 1 Explosion of sustained offense from Clayton. Jabs, crosses and hooks, giving Muñoz no room to breathe. 10-9 Clayton
Round 2 Muñoz is being dominated and frozen in place as Clayton flashes hand speed at him. Stone-skipping right hands by Clayton, finding it difficult to miss. Probably not much resistance left in Muñoz, and he isn't offering much of anything to slow Clayton down. 10-9 Clayton 20-18 Clayton
Round 3 Muñoz, who is a late sub on 48 hours' notice and didn't bring anybody to work his corner, is getting pummeled. Ref should wave it off soon in any event. This is just Clayton teeing off, Muñoz playing the wooden karate dummy (but with more wobbling). 10-9 Clayton 30-27 Clayton
Round 4 Clayton starting to dig in with a few body shots mixed into his onslaught, switching tacks as none of the many clean head shots he is landing are putting Muñoz away. Muñoz just soaks it all up, hanging in there, no quit - but is hardly getting a punch in edgewise. 10-9 Clayton 40-36 Clayton
Round 5 Muñoz is circling and putting his forehead down, chin tucked, gloves up and waving about to catch what he can. Occasional jab. Clayton meanwhile is studying his target and finding spots to land everything he wants, body and head, both hands, singles and combos. 10-9 Clayton 50-45 Clayton
Round 6 Muñoz is getting stifled by the work rate and power of Clayton, but not submitting to it. Clayton is doing as he pleases, experimenting with landing on Muñoz with different shots from various angles. 10-9 Clayton 60-54 Clayton
Round 7 Muñoz is finally starting to appear hurt. Clayton piling on the punches. Muñoz takes heaps of abuse yet manages to stay erect for the full three minutes. 10-9 Clayton 70-63 Clayton
Round 8 Muñoz still has no answer for Clayton's attacks, nor is he likely to produce any now that he is withered and pulped up. Muñoz is getting hit with solid right hands and Clayton then rushing to follow-up with body shots as Muñoz is recovering. 10-9 Clayton 80-72 Clayton
Round 9 Muñoz is egging Clayton on, indicating he can handle more. Clayton obliges and pours it on, going to head and body. Low blow from Clayton, according to Muñoz, seeking remedy from the ref. Clayton takes advantage with a lead right hand on the button - and finally knocks Muñoz out! Protect yourself at all times! KO9!!
