Gael Monfils moved up to No. 23 in this week's ATP rankings after winning the Open Sud de France on Sunday. With his seven-spot jump, the 27-year-old Frenchman reached his highest ranking since July 2012.

A year ago, Monfils was out of the top 100 after missing nearly four months with a knee injury. But he's now already won a title, the fifth of his career, and been a runner-up, at the Qater Open, this year.
