No American men reached the fourth round of the Australian Open for the second consecutive year, but Sam Querrey doesn't think it's necessarily a reflection on the state of American tennis.

The top American player, No. 13 John Isner, pulled out before the tournament began with a knee injury and veteran Mardy Fish, currently ranked 27th, skipped the Australian Open as he continues to recover from heart problems.

"If they were here, hopefully one of them would have made it,'' Querrey said.

Querrey, seeded 20th, was the last American man standing in Melbourne until he lost in the third round Friday to 15th-seeded Stanislas Wawrinka of Switzerland.

"We're doing our best,'' Querrey said. "I don't think the state of American tennis is poor, you know, I think it's pretty solid if you compare it to most countries. You can argue we're in the top five overall, maybe.''

The U.S. didn't have any men in the fourth round last year, either. And that was with Isner, Fish and the now-retired Andy Roddick playing in the tournament.

No American man has won the Australian Open since Andre Agassi in 2003, and no one has won a major since Roddick at the 2003 U.S. Open.
