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.

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 in Cincinnati and the China Open in Beijing, earning her a fourth consecutive qualification at the year-end BNP Paribas WTA Finals Singapore presented by SC Global.

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.
