Since the inception of computer rankings in 1975, Halep becomes the 13th WTA player to achieve the year-end No.1 singles ranking, and the first from Romania.

“Our congratulations to Simona Halep who is a worthy winner of the WTA year-end World No.1 singles ranking. Simona has had a great season, winning the title in Madrid and reaching the final at Roland Garros,” said Colm McLoughlin, Executive Vice Chairman & CEO, Dubai Duty Free. “We wish her well for the remainder of the year and look forward to seeing her play in Dubai in the near future, where she won the title in 2015 and has many ardent fans.”

The Romanian became the 25th player to achieve the No.1 ranking on October 9, 2017 following her 27th career WTA final at the China Open in Beijing, and is ensured to retain the position as the top player for the rest of the year.

“I’m very proud to end the season as the WTA World No.1,” said Halep. “I have worked extremely hard to be the best player I can be, and it is an honor to be in the No.1 position at the end of the year.”

Halep has enjoyed another consistent season, highlighted by defending her title at the Mutua Madrid Open and reaching her second Grand Slam final at Roland Garros. In addition, the 26-year-old reached the title match at the Internazionali BNL d’Italia (Rome), Western & Southern Open (Cincinnati) and the China Open (Beijing), earning her fourth consecutive qualification at the year-end BNP Paribas WTA Finals Singapore presented by SC Global.

This season, Halep also made a quarterfinal run at Wimbledon, as well as semifinal showings at the Porsche Tennis Grand Prix (Stuttgart) and Rogers Cup (Toronto).

Halep entered the Top 10 for the first time on January 27, 2014, and has maintained her Top 10 status for 196 consecutive weeks. Having made her debut in the Top 5 in the spring of 2014, the Romanian has spent just eight weeks below that threshold.
