Those of us who follow Jelena Jankovic closely were thrilled when JJ hired back her former coach, Ricardo Sanchez, for she has always played her best tennis under his watch. But the second Jankovic-Sanchez team has split, too. Sanchez has signed a one-year contract with Caroline Wozniacki.
There's more: Sanchez was not the "mystery coach" helping the world number 1 during the U.S. Open--the one whose name was supposed to have been revealed right after the Open. So the Mystery Coach remains a mystery, and the next question is: Who will coach JJ?
