Kerrius collapses again during his defeat in Cincinnati

Nick Kerrios continued to argue with referee Fergus Murphy during Cincinnati Masters' second round defeat against Karen Khchanov on Wednesday night and insulted the referee heavily before leaving the field to destroy some speculators.

The Australian expects a heavy penalty from ATP after fighting with the referees for the second time in two weeks and Murphy for the second time this month, collapsing in the defeat 6-7, 7-6 and 6-2.

Kieros' s disputed with Murphy at the end of the second set and accused him of having started the time set for early transmission.

He was penalized one point at the end of the second set qualifiers after insulting the Irish referee.

The 24-year-old, who was not in the tournament, left the field to go to the restroom and despite Murphy's objection, the pictures showed that Cereus was pushing snowshoes into the tunnel leading to the court. .

Kerrius, who left the field without shaking hands with Murphy, defeated the Irish referee two weeks ago at the Washington Open, where he won the title and played with a referee at the Rogers Cup in Montreal last week.

Murphy had already been insulted by Kyrios at the Queens Championship in June.

The eighth-seeded Russian Khchanov remained calm and ended the match with three straight games against France's Luca Boy, who beat Canadian Denis Shapovalov 6-4, 6-4 for a quarter-final spot.

The German Jan-Lenard Struff did not survive the uprising of Stefanos Titipas, while young Serbian Miomir Kismanovic beat fifth-seeded Alexander Zverev in the tournament's two biggest surprises.

Struve, who is still looking for his first individual singles title over his 10-year career, was the best player for most of the match against his 21-year-old Greek rival.

With his service kicked out in the second set, Titipas managed to keep his hopes alive and both players used a playoff group.

However, the German refused to surrender and won 6-4, 6-7, 7-6 to qualify for the third round against the ninth favorite Daniel Medvedev, who beat the French Benoit Bear 7-6 , 6-1.

"I was lucky enough to win the match at 6-4, 5-4, but my mission was broken and that's what he did," said Struff.

"The efficiency that I appreciated (in the game) stems from that and I had the opportunity to settle the game in two straight sets, then again when I advanced 6-3 in tie-break ( in the third set) and then to the draw 6-6. "

"Titipas was doing very well. I told myself: I have to try it otherwise I will not win. "I worked hard with my team on the physical side and finally, it paid off and I kept fit."

But his German compatriot Zverev was less persistent and made 20 double mistakes in his loss to Kismanovic, 19, who lost 6-7, 6-2, 6-4.

This is the first victory of Kismanovic, the second youngest player in the top 100 in the world, against a player in the top 10 in the world and he will come out of the top 50 when it comes out next week.

World number five Ki Nishikori was beaten 7-6 by 6-6 by Japan's Yoshihito Nishioka.

World number one Novak Djokovic and third seed Roger Federer qualified for the third round on Tuesday.
