Federer: The 2007 champion

The US Open has upped its prize money by $1million for this summer's tournament.

The total prize fund will now be $20.6m - with up to $2.6m extra available in bonuses.

The winners on the men's and women's singles title will each win $1.5m each, with a further £1m possible depending on performances in a series of US Open tune-up events.

Roger Federer collected the biggest cheque in tennis history after his $2.4m pay-day at last year's US Open - with the Swiss ace winning the most points from the competitions leading up to the event.
