Rafa Nadal, superhero. Well, a few punters might not be thinking that tonight.
del Potro, having not won a set against the top three players before in abotu 8 matches, led by a set and a break, before Nadal fought back to a set all.
Nadal then led 3-0 in the final set with two breaks. And that's when the money buyers would have stepped in. £421k at 1.01. OUCH!
