Let's say hypothetically they both reach the finals. Who would you bet on. Case for Fed: 6 Wimby's . One of the greatest grass court players ever. Won it last year. No visible signs of a big decline yet. Case for Nadal. Currently the 2nd best grass court player after Fed. Won it 2008. Seems to have the mental edge over Fed in slam finals. Gets better on grass every year. I think I would keep my money in my pocket!
