Carlos Alcaraz debuted a new look as he progressed to the third round of the Shanghai Masters, sporting a moustache along with all his team in the stands.
The second seed swept to a 6-3 6-3 victory over Argentina's Juan Manuel Cerundolo. He revealed the facial hair agreement came as a result of his first title since February in Tokyo earlier this week.
"It's going to stay for the week," said the Spaniard. "I always wanted to step on the court with a moustache.
"Before Tokyo it was like, 'All right, if I win the tournament, we all have to have the moustache and play Shanghai with a moustache'. It's going to be fun, we're laughing around, just having fun with it."
Monaco's Valentin Vacherot, who won the title in Shanghai last year as a qualifier, opened his campaign with a 6-4 7-6 (5) victory over Sebastian Baez.
Fourth seed Felix Auger-Aliassime needed nearly three hours to see off Camilo Ugo Carabelli 4-6 7-6 (1) 7-5, while Daniil Medvedev, playing his first match since being defaulted in Beijing for hitting a spectator with a loose ball, also came from a set down to beat Jan-Lennard Struff 4-6 6-4 6-3.
Stefanos Tsitsipas overcame a delay of more than 15 minutes caused by overly bright screens at the back of the court to see off 18th seed Luciano Darderi 6-3 6-4.
