Kei Nishikori knocks out Marin Cilic 7-5, 6-7(8), 6-3, 6-7(3), 6-1 in four hours and 59 minutes, his fifth straight win after coming through qualifying to reach the main draw. Both players received treatment during the match, Nidhikori for ramps in his calf and Cilic for his back.
"I was cramping from second set, third set," said Nishikori. "But I keep fighting, keep fighting and get a fourth-set tiebreak, that was key for me."
