When Andy Roddick was recently asked for the umpteenth time about the apparent decline of tennis in his country, the world number 10 gave a weary response.
"I think we're kind of a victim of our own success over the years in the sport," he said. "If you still stack us up against most countries, we're coming out ahead."
Tennis has always had a strongly international flavour, but for every Borg, Lendl, Becker or Edberg, there was always a McEnroe, Connors, Sampras or Agassi.
That balance is now shifting away from the US, raising questions for the sport.
At Wimbledon this year there were no US players in the women's quarter final, and only one man – Mardy Fish – in the last eight.
The US has been the leading market for tennis and still boasts more tournaments than any other country – 12 on the men's side and 10 on the women's, as well as the richest purse at the US Open – but the battle for TV viewers and on-site spectators is fierce.

With that in mind, "global" is the key word on tennis administrators' lips these days, and it seems the American audience is holding firm for now.
"Television numbers haven't wildly fluctuated between, say, Serena Williams winning the women's side of a major on a Saturday and Roger Federer winning the men's side on a Sunday," says Eric Abner of Tennis Channel, an American subscription service that covers almost every event in the tennis year.

"Alongside the general similarities in viewer tune-in at all four Grand Slams throughout the year, regardless of the champions' countries, it would suggest that strong, entertaining performances from well-known players is more of a factor than contender nationality."
The leading names, such as Rafael Nadal, clearly carry a level of interest no matter where they
