I feel like so many people forget just how advanced in age Roger is, tennis-wise. Nobody at age 34 has ever done what he's doing now.
Federer has already played more matches in his career than Agassi did in his entire career - and he retired at 36.
I'm in disbelief that Federer pulled out that victory. Heart of a champion.
Tomic withdrawing is why I want to see a setup where the guy who lost the previous round's match (Kokkinakis here) gets through instead.
I declare henceforth that Roger Federer is better at being a 34 year-old athlete than any 34 year-old has ever been at anything.
