Does anyone know why he plays. Aren't his off weeks or days his only chance to rest or train during a busy summer schedule. My parents watched him lose to Jaimie (sp) Delgado in St Louis World Team Tennis. I was shocked that he showed up at all. How much can they pay him for appearing. The matches can harldly get a 0.5 rating on ESPN2 at 10pm on weeknights, a sold out venue was 2000 seats each sold for not much more than $50. Where does the revenue come from to pay a Roddick or Venus Williams what must be a huge appearance fee. Seems like he'd be smarter to train or recuperate to give him some small chance of winning the USO again (like if Fed gets stuck on the 7 train heading to Queens and defaults).
