Tired yet?

I don't often suggest this to players (especially not women players, given the lack of depth), but really, Jelena Jankovic, take a week off. Or three.
Jankovic's run this fall has been impressive. She's been great all year, actually. But, who wants to bet that by the year-end championship, she'll have nothing left?
A better question: Who wants to guess how many tournaments Jankovic has played this year? And compare it, to say, Serena Williams?
Here's someone who does what no one else does -- play a full schedule -- and yet comes up empty at every Slam. It's almost not fair, but part of being a consistent pro has to do with taking care of yourself, pacing yourself. If Jankovic has a deep run this week in Zurich, that'll give her about two weeks to recover from playing nonstop for a month.
The word is not "cast". It's "balance". We've seen the opposite happen (ahemVenusWilliamsahem) where certain players take weeks off at a time, then falter in early rounds. Even Williams, though, manages a Grand Slam with her scheduling. It's next to impossible for Jankovic to play every tournament, and still be tough enough to win a major. Kudos to her coaches and mom for making her the world's best. Now they just have to make sure she can stay that way for a long time.
No takers on how many tournaments she and Williams have played this year? No cheating. I already did that.
