Tickets for next week's Laver Cup in London have skyrocketed to nearly £60,000 (NZ$114,424) after Roger Federer announced it as his final competitive appearance.
The 20-time major champion's retirement news was not completely unexpected due to his age and knee injuries, but the confirmation sent shockwaves across the sport. It has also made his final appearance, at London's O2 Arena next week, the hottest ticket in world sport.
Less than an hour after Federer's announcement, the ticket site was experiencing lengthy queues for the few seats remaining. Tickets in the stands closest to the court for the weekend sessions of the three-day event were being resold on Stubhub for as much as £23,900, and by Friday night had reached £59,000.
Although the event – billed as the Ryder Cup of tennis – is arguably a glorified exhibition, it has proved popular with fans who get a rare opportunity to see their favourite players on a team together.
Even before Federer's retirement news, this year's event was set to be groundbreaking as the so-called Big Three – Federer, Novak Djokovic, Rafael Nadal – as well as three-time grand-slam champion Andy Murray signed up to represent Team Europe together for the first time.
