The strike itself is not lucky, he had been trying to land it earlier although unsuccessful. The lucky part is, he landed it with 1 sec left, that is amazingly lucky. All KZ had to do was not march forward the last 10 seconds, but then, he wouldn't be KZ if he played it safe. Most fighters would've ran out the last 10 seconds or even the whole last rd, but that's not KZ's style. The official scorecards were shown on MMAWeekly, KZ would've won the decision if he played it safe the last 10 seconds, but again, its not the type of fighter he is. Props to Yair, hard won fight. No fluke
