Two-time semi-finalist Daniil Medvedev took his frustration out on his racquet after he suffered a shock first-round exit at Wimbledon.
The Russian world number nine lost 7-6 (7-2) 3-6 7-6 (7-3) 6-2 to the 64th-ranked Frenchman Benjamin Bonzi before slamming his racquets against his chair and his bag.
It is the first time Medvedev, who made the last four in the past two years, has failed to reach the second round in seven Wimbledon appearances.
It was a first ever victory over a top-10 ranked opponent for Bonzi, 29, who has matched his best Wimbledon result by reaching the second round.
Medvedev was not the only men's seed to fall on day one as Danish eighth seed Holger Rune lost a five-setter and Greece's Stefanos Tsitispas retired injured.
Elsewhere on Monday, Greek former world number three Tsitsipas, 26, retired because of a long-standing lower back injury after the 24th seed fell two sets down against French world number 113 Valentin Royer.
Tsitispas said he had no answers to his ongoing fitness problems that were showing no sign of easing.
Meanwhile, world number eight Rune let slip a two-set lead against world number 143 Nicolas Jarry of Chile, losing 4-6 4-6 7-5 6-3 6-4.
Italy's Matteo Berrettini, the 32nd seed and 2021 finalist, is also out after losing 4-6 6-2 6-4 5-7 6-3 to Kamil Majchrzak of Poland.
