The exhibition between Roger Federer and Alexander Zverev at the Plaza de Toros in Mexico City has broken the record for the largest crowd to watch a tennis match with announced attendance of 42,517 spectators.
The previous record was 35,681 spectators for an exhibition between Kim Clijsters and Serena Williams in 2010 in Brussels.
Federer won the friendly encounter, 6-3, 4-6, 6-1.
"It means the world for us and tennis to get to write history in Mexico," Federer was quoted having told the crowd. "It has been 23 years I haven't come to Mexico and what an error I made. It gave me the opportunity to play in front of one of the best crowds, I have chills."
Alongside the singles, Bob and Mike Bryan played a doubles exhibition with Mexican pair Santiago Gonzalez and MiguelReyes Varela.
The event is part of Federer's South American tour, which has also included an exhibition in Santiago, Chile with 13,000 spectators, in Buenos Aires with 14,000 spectators and a scheduled appearance in Bogota, Columbia in front of 8,000 spectators that had to be called off because of a government curfew to contain protests in the country. The next event is in Quito, Ecuador.
