Querrey: Return to Top 20 will be slow

Former Top 20-player Sam Querrey scores just his second win in seven matches this year when he defeats Alejandro Falla in Memphis, 2-6, 6-3, 6-4. The 24-year-old American has fallen to No. 99 in the rankings. He was sidelined three months last summer after elbow surgery.

Querrey has begun to work coach Brad Gilbert on a trial basis. "It's tough because I feel when I'm playing well I'm a Top 20 player, but I can't jump right back into the Top 20 by making the semis here," Querrey told reporters. "It's a process and it's frustrating, but I've kind of come to terms that it might take six to eight months to get myself back to where I was."

His sometimes doubles partner John Isner added. "It's only a matter of time before he gets back in the Top 20."
