Controversy!

Well this is fun. In case anyone is missing this, Nadal just left, and Wawrinka was demanding to know the reason. After about four minutes of arguing, the judge just told him he should accept the situation and move on. Wawrinka jogged a bit, and Nadal returned after about a seven-minute break.

Nadal then basically proceeded to stand still for four hits, giving Wawrinka an easy 3-1 lead in the second set.

He's obviously hurt or something, and this match could end sooner than anyone expected. Of course this is disappointing to those of us who have watched this exciting tournament and have been expecting a competitive final.

But now it's 4-1 in the second and going downhill fast.
