Nadal and Halep continue to be on top
Madrid: Spanish tennis player Rafael Nadal remained in the number one spot in the men's Association of Tennis Professionals world singles rankings released on Monday.
Nadal, 16-time Grand Slam champion, was followed by Switzerland's Roger Federer, who won the Swiss Indoors Basel on Sunday, reports Efe.
Britain's Andy Murray came in third, while German Alexander Zverev jumped to the fourth position, ahead of Croatian Marin Cilic, who dropped to the fifth. After winning the Swiss Indoors Basel, Federer announced that he would not take part in the upcoming Rolex Paris Masters, so he practically has no chance to snatch the top spot from Nadal this year.
Meanwhile, Romania's Simona Halep continued to lead the Women's Tennis Association rankings released on Monday while Denmark's Caroline Wozniacki came in third.
Wozniacki, 27, climbed three spots after she beat American Venus Williams, who occupied the fifth place, to win her first WTA Finals title in Singapore on Sunday, leaving Ukrainian Elina Svitolina in the sixth spot, reports Efe.
Spaniard Garbiñe Muguruza remained in the second spot while Czech Karolina Pliskova fell to the fourth.
