Indoors, where Cilic prevailed in straight sets. During the round-robin stage of the Year-End 2016 ATP World Tour Finals, Cilic came from a set down to defeat Nishikori and ultimately prevail. Most recently, Nishikori defeated Cilic in the quarterfinals of the Monte-Carlo Masters by a score of 6–4, 6–7, 6–3. At the 2018 US Open, Nishikori and Cilic again met in the quarterfinals. In a five set thriller, Nishikori won a spot in the semifinal of the US Open for only the third time (and only the third time advancing past the quarters in any of the four majors). Equipment and endorsements Nishikori has endorsed the Wilson Wilson Burn 95; however, it is believed by racquet enthusiasts that he used an older modified Wilson nCode nTour underneath the Steam paint job.
