Rafael Nadal will headline a Fast4 exhibition in Sydney starting January 11th.
The former world number 1 will be joining Gael Monfils, Lleyton Hewitt and Nick Kyrgios.
The expanded event, which follows last year's launch featuring Hewitt and Roger Federer, has an experimental format with sets won by the first player to four games, no deuces and play continuing after lets on serve.
"It's easy for the crowd to get involved in every point which makes for a great atmosphere," Nadal said.
The format has been piloted at clubs across Australia and is being billed as the tennis equivalent of Twenty20, the short form of cricket which has proved a commercial hit.
Nadal, Monfils and John McEnroe will form a world team while Hewitt, Kyrgios and Pat Cash will represent Australia.
