It must feel pretty bad for these kids to lose to a 40% Federer who's been skipping practices and was thinking of pulling out of the tourny.
Next two rounds won't be fun. Del Po should beat him in this form, but if he gets Istomin, he'll be through to Nadal.
Just another chance for the h2h to get worse, so not a great prospect.
At least he'll have an excuse this time
Top 4 have looked pretty crap this tournament.
