PARIS — Sixth-seeded Andrey Rublev berated his own behavior after he was knocked out of the French Open by Matteo Arnaldi 7-6 (6), 6-2, 6-4 in the third round on Friday.
Rublev showed frustration throughout over his lack of precision, committing 37 unforced errors and four double faults. After netting a forehand in the third set, he smashed his racket on his knee four times.
''I am completely disappointed with myself, with the way I behaved, the way I performed, and I can't remember ever behaving worse in a Grand Slam tournament," he said. ''It was the first time I ever behaved that badly.''
Arnaldi disagreed.
"You all know him. He does those things almost every match. Personally, I don't pay too much attention,'' Arnaldi said. ''But it definitely does give me a little confidence, because it means I am giving him trouble, and what I was doing was working. It can give me a bit of a lift and give me some more energy in the following points.''
Rublev entered the French Open as a contender after winning the Madrid Open this month.
Arnaldi, ranked 35th, will face Stefanos Tsitsipas or Zhizhen Zhang, who were scheduled to play later Friday.
No. 2 Jannik Sinner progressed by downing Pavel Kotov 6-4, 6-4, 6-4.
