SINGAPORE - Simona Halep joins the WTA Insider Podcast for the last time in 2017, after finishing the season as the 13th woman and first Romanian to hold the WTA Year-End World No.1 singles ranking, presented by Dubai Duty Free.

"It's a great feeling," Halep said on the WTA Insider Podcast. "It's tough to express the feeling in words, but what I feel is I did everything I could until today to get here, to get to No.1 in the world. Everything was difficult during the time and during the years. Now it paid off and I feel just happiness and nothing else."

"I dedicated my life to tennis and I don't regret that. It's the best moment that I ever had in my life, this one today. All I can say is that I love this sport and I love that I am in its family."

Hear more from Halep's 2017 exit interview, as she reflects on the importance of both Darren Cahill and Virginia Ruzici in her career. And she caps it off by taking the No.1 quiz. No.1 movie? No.1 TV show? No.1 thing she's looking most forward to in the off-season? Halep endures the quick-fire challenge.
