"I'm not going to tell you what Cos thinks about Cincinnati" - Kyrgios on if his girlfriend is enjoying her stay in the city

Nick Kyrgios had a whirlwind affair during his run at at the Western & Southern Open, looking dominant in his opening round victory over Alejandro Davidovich Fokina before falling quietly to Taylor Fritz in the second round.

Before the Aussie's time in Cincinnati came to an abrupt end, he seemed relaxed and in good spirits. The former World No.13 was even seen poking fun at the host city of Cincinnati, saying that there was nothing much to do off the court for him and his girlfriend Costeen Hatzi.

The 2022 Wimbledon losing-finalist also revealed that he lost his phone a day earlier at Kings Island, an amusement park in Ohio.

"Well, I'm not going to tell you what Cos (his girlfriend Costeen Hatzi) thinks about Cincinnati," Kyrgios said. "I've played some best tennis here and I really like it. It's actually good that there's not much to do off the court, which makes me stay in and get a good rest. I went to Kings Island yesterday and lost my phone already. I was on a roller coaster and checked my pocket, gone."

The Cincinnati Open is the only ATP Masters 1000 tournament where Kyrgios has reached a final; the Aussie lost to Bulgaria's Grigor Dimitrov at the 2017 event. At the Canadian Open last week, Hubert Hurkacz broke Kyrgios's nine-match winning streak, beating him 7-6(4) 6-7(5) 6-1 in the quarters.

The Cranberra native will now set his sights on producing a solid performance at the US Open, which begins on August 29.
