Tennis: No American men left in Australian Open 4th round

MELBOURNE (AP) - No American men reached the fourth round of the Australian Open for the second consecutive year, but Sam Querrey does not think it is necessarily a reflection on the state of US 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 on Friday to 15th-seeded Stanislas Wawrinka of Switzerland.
