WTA players reveal what it's like to play a world No. 1

For almost the entirety of 2018, Simona Halep was at the top of the rankings. Since October of 2017, the Romanian has held the No. 1 ranking—except for four weeks in February after Caroline Wozniacki beat her in the Australian Open final.

Halep attacked right back by winning the French Open and retaking her throne.

Top WTA players have revealed what it was like to face the best player in the world in a new feature video. A highlight is Sloane Stephens talking about the final in Montreal, which she considers the shining match of the year, despite losing 7-6 (6), 3-6, 6-4.

"My best match of 2018 was the Montreal final against Halep," Stephens said. "That was such a battle of a match. I didn't win, but I think for the whole year overall that was the best match that I played from start to finish."

Halep also reached the final in Rome and Cincinnati, while taking home the titles in Paris, Montreal and Shenzhen. We'll see if her streak continues into the new year as she has recently announced that she will start the 2019 season without a coach.
