After an official review, the bout between Petchmorakot versus Petroysan was overturn to a “No Contest” because illegal clinching was not adequately controlled by the referee.
How much time was wasted because the referee had to repeatedly break the fighters during clinch?
..and how does that compare with the time in break of the other quarter-final fights?
We will answer those questions using few charts.

The tale of the numbers

Time in break by round

Last month ONE Championship put out an amazing fight card with 8 among the best kickboxers in the world battling for the kickboxing featherweight belt and the 1 million dollar prize. The event delivered some breathtaking action but also one of the biggest controversy in the recent kickboxing history: Petchmorakot versus Petroysan was overturn to a “No Contest” because of the illegal clinching by Petchmorakot.

Why was the clinching by Petchmorakot considered illegal? In a facebook post, the ONE Championship CEO Chatri Sityodtong explained that [clinch]…“is not allowed for stalling, tying up an opponent, or holding. It is also not allowed directly after an attack as a defensive technique. Under ONE rules, the clinch is ONLY allowed for offensive aggression with strikes”.

Lawrence Kenshin expended on that with an in-dept video analysis and breakdown of the fight. Here is an extract of the video in which he explains some of the key concepts behind the “No Contest” decision (make sure to check the full video of Lawrence Kenshin):


In other words, kickboxing is all about continuing striking action, and thus fighters are expected to “transition out of clinch without referee”. When the fighters engage in clinch and hold after, they force the referee to step in and break them, taking away a lot of time from the real action.

How much time was taken away from the action by the referee breaks?
I analyzed all the four fights and recorded the time in break (time from the referee saying “Stop” to “Go”). I did not include breaks resulting from knock downs or cut kicks that are normal part of an “healthy” striking action.

The following chart shows for each round (in the x axis), the percent of time (y axis) spent in break. Data of each of the fights is displayed in a different colored column.

In round1, action was mostly continuous in all of the 4 fights and time in break was not more than 10% of the round time (Askerov-Kehel: 18 sec). Petchmorakot-Petrosyan were in break for about 5% of the round (10 sec that included the low blow by Petrosyan), whereas Yodsanklay-Sana and Nattawut-Moisa gave us a round of unstopped (or almost unstopped) action.

In round2, time in break went up in all the fights, but to an alarming level in Petchmorakot-Petrosyan. Askerov-Kehel, Yodsanklai-Sana and Nattawut-Moisa spent ~20%, 13% and 3% of round2 in break, respectively. On the other hand, Petchmorakot-Petrosyan had almost 30% of round2 in break…52 sec of the 180 sec of the round not fighting! Noteworthy, the measure that I am reporting here is the time in which action is not allowed (the referee said “Stop”), and so does not include other inactive periods (in clinch or outside) in which action is permitted but fighters do not engage. In other words, the current measure is quite conservative and presumably is an underestimate of the inactive time of the fight.

Why did break time increase of 5 fold (from 10 to 52 sec) in round2 of Petchmorakot-Petrosyan fight?
Well, we know that this was part of (or a collateral effect) of Petchmorakot’s strategy for landing knees. In a post-fight interview Petchmorakot said: “I changed my strategy going into the second round. My manager, Mr. Nuttadaj, told me to use my reach, jab my way in, and land the left long knee”

He also added: “Going into the third, I stuck with that game plan, and it worked.”

And indeed Petchmorakot stuck with his strategy and time in break remain quite stable in round3 (~27%, 49 sec). Also in Askerov-Kehel and Yodsanklay-Sana fights the time in break did not change considerably and remain under or equal to 18% of the round time (≤34 sec). There was no break due to holding in Nattawut-Moisa round3 but in that round Moisa was knock down twice and then TKO at 1’36”.

Total time in break

In total, Petchmorakot-Petrosyan spent 111 sec of the fight in break (that is dangerously close to 2 minutes of no fight). How does that compare with the totals of the other fights?

Table 1: Total time in Break
Relative to Petchmorakot-Petrosyan
Fight sec sec percent
Askerov-Kehel 87 -24 -27%
Yodsanklai-Sana 58 -53 -92%
Nattawut-Moisa 9 -102 -1104%

Among the 4 fights of the quarter final, Petchmorakot-Petrosyan was the fight with most time in break, followed by Askerov-Kehel (87 sec), Yodsanklai-Sana (58 sec) and Nattawut-Moisa (9 sec; table above). Askerov-Kehel spent ~24 sec (~27%) less in break than Petchmorakot-Petrosyan.
Is this difference of time in break between Petchmorakot-Petrosyan and Askerov-Kehel big enough to justify alone the overturn of one of the fight but not the other? There are a couple of considerations that need to be made to answer that question. 1) Petchmorakot-Petrosyan overturn was also motivated by the fact that, of the 2 fighters only one was almost exclusively responsible for the holding and defensive clinch. Lawrance Kenshin argued in his analysis that there was enough ground for deducting multiple points to Petchmorakot. 2) When put it in prospective, the difference of time in break between Petchmorakot-Petrosyan and Askerov-Kehel is not trivial. Petchmorakot-Petrosyan spent 24 sec more in break than Askerov-Kehel. That is equivalent of having 3 separate 8-counts more of inactivity in in Petchmorakot-Petrosyanthan fight than in Askerov-Kehel (i.e. on the top of 87 seconds) but… without even a knock down. Just few days ago we were reminded that 8 seconds can be enough to get back on your feet after a knock down and punch your way to a win (i.e. Joshua-Ruiz!).

Single breaks

Why did Petchmorakot-Petrosyan spent more time in break than the other fighters? Were the breaks more numerous or were they longer than in the other of the quarter-final fights?

Well a little bit of both.

In the chart above, each point represents a break. The length of the break is indicated on the y axis on the left, the fight where the break was observed is reported on the x-axis on the bottom. Again, we have different colors associated to different fights. The more the points are high, the more the breaks are long. If you see many points of the same color, then that means that there were many breaks in that fight! As you can see, there were numerous breaks in Petchmorakot-Petrosyan but also in Askerov-Kehel (where Onari was a referee too). The problem is that the breaks in Petchmorakot-Petrosyan fight tended to be longer than in the other fights! There are 5 breaks that lasted between 6 to ~7 seconds in Petchmorakot-Petrosyan, but only one that is that long in Askerov-Kehel fight.

Why did it took so long? For 2 reasons. In some of those breaks the referee talked to Petchmorakot, and that took extra time away from action. In others, the referee had to physically separate the fighters, a process that eats up time.


Petchmorakot-Petrosyan spent more time in break than any of the quarter-final fights. A total of ~111 seconds of that fight were spent actually…not fighting (break time), with most of this inactive time in round2 (52 sec, 29% of round time) and round3 (49 sec, ~27).

The breaks in Petchmorakot-Petrosyan were numerous but also tended to last more than in the other fights. This was due to the extra time needed by the referee to talk to Petchmorakot and/or to actively separate the 2 fighters.

And so? I enjoyed the fight and I was not that excited for kickboxing tournament since the time of the old K1 of Masato, Buakaw and Souwer. I think that Petchmorakot is an extremely dangerous fighter also under kickboxing rules and he showed it to us by landing some heavy punches and quite scary knees. So…I just hope that there will be soon a rematch!

EDIT: July 6.

…and ** a rematch has been confirmed**

Rematch between @petchmorakot.official and @giorgiopetrosyan is confirmed. They are fighting on 12 July in Kuala Lumpur 💥💥 @yindeeman posted this on his personal facebook, "The hardest decision ever in life!!! It was two weeks that I was very stressed about the situation that occurred between ONECHAMPIONSHIP and PETCHYINDEE over the fight of Petchmorakot vs Petrosyan. After the competition end, a lot of Petrosyan fans came to our social media channels such as Facebook page and Instagram. Most of them said we were cheating, we stole their victory. At first we tried to understand them as they might still in shocked that their idol was unbelievably defeated. Nevertheless after ONE CHAMPIONSHIP announced the rematch of Petchmorakot with Petrosyan, I was truly in shocked and I don’t think this is a fair decision. Thus, as you all known Petchmorakot had announced to withdrawn himself from the competition. The situation had become worse as once Petrosayn’s fans knew that we had withdrawn, they all came to say that we are coward or we were afraid to fight with Petrosyan even the victory that we get were came from cheating. Petchmorakot who was ordained as a monk had called me to give him a chance to fight for his honor and to prove to everyone that he deserve the victory. Until two days ago, I received a call from Khun Chatri about the solution of this issue. ONE CHAMPIONSHIP apologized for the incident and explains to me about the Kickboxing rules which lead to a lot of misunderstanding between the fight, in this point to REMATCH is the best option for both of them. For Petchmorakot, Khun Chatri proposed 1 million baht for his fighting fee along with giving him the opportunity to fight in WORLD GRAND PRIX which is in Muay Thai rule with the price of 1 million dollars no matter how the result of this match will be. ONE CHAMPIONSHIP confirmed that this rematch will be fair to both sides and the judgment of this rematch will be final. Then I asked Pra Petchmorakot for his decision while I ready to give him all money without any deduction no matter the result is, in return of his hard work and to encourage him to the victory.
