Re: Jankovic needs to tank tomorrow match if she needs to go far @ Wimbledon
Her points have not been very long. She's had a rest day here and there and the weather has appeared to be fairly moderate. Had she not played these tournies she would have likely been practising everyday. Physically, it's nearly identical, the only difference is that she's being mentally challenged. This is what makes you stronger.
She'll do just as well at Wimbledon whether or not she plays tomorrow at 100%. For world class players, it's not a question of physical exhaustion, it's mental fatigue.
