Wawrinka leads the head to heads 3-2. Their most recent meeting was in Canada in July and Nishikori won on a hard court in straight sets.
Nishikori had an excellent win over Murray in the last round. He took that match in 5 sets. He had played 4 sets in each of his previous 4 rounds.
Wawrinka was up against Del Potro in the last round who had been playing better tennis yes as he often does Wawrinka raised his game for the big occasion.
I think Wawrinka will be the fresher player and we have real value on him today. In their last 3 matches it was the underdog who won. Wawrinka has only once been the underdog which was at the Australian Open last year. He won that in straight sets.
It should be a great match!
