Love Nishikori's game!
He certainly had some nice shots in that first set, lost 6-2 to Ferrer. Seems to be fading a bit now however.
Looking increasingly like Novak, Fed, Murray, and Ferrer for the semifinals; the same four as in Sydney two years ago. Ferrer nearly won his semi against Murray, I recall. Murray played a lot better then than in the final.
But if this comes off, it will be a different pairing this time and it looks to me more and more like a Djokovic - Federer final
