Wawrinka takes the first set

So Wawrinka's first serve was his weakness in that set, yet he still won the set. All tournament Wawrinka has put the ball where he's wanted to put it. Nadal does look a bit worried, but he didn't play his best tennis in that set. Still, Wawrinka has this way of looking like he's hitting a desperation shot and slinging it past his opponent. He looks like the clear favorite so far.
