Nadal was clearly not at his best, and went off the court to receive treatment down 3-6, 1-4 for more than 7 minutes. He also started receiving treatment for his back on the court during every changeover in the second set. It looked like Nadal might retire from the match when he was down 1-5 in the second set but he played on and Wawrinka's level dropped and he went down a break early in the 3rd set after closing out the second.
In the end, Nadal started playing better and started holding serve regularly to win the 3rd set and things proceeded on serve in the 4th set as well until the 6th game when Wawrinka broke again. However, Wawrinka was unable to hold serve but was able to break Nadal for the second consecutive service game. Then holding a 5-3 lead Wawrinka easily served out the match game at love.
