WTA star Jelena Jankovic, the No. 6 player in the world, spent her Tuesday training on the hard courts at IMG Academy Bollettieri tennis program in advance of next month's U.S. Open.
Jelena has 10 career WTA singles titles and rose to a No. 1 worldwide ranking last year.
Several junior summer tennis campers got a chance to watch her practice, and she offered a few autographs during breaks in the action.
