Federer's reign as world number one comes to an end
Roger Federer's reign as the world number one was short lived, as he lost the Halle Open final. Federer's nemesis Rafael Nadal has regained the number one spot in the men's ATP rankings. Federer had skipped the French Open but made a strong start to the grass court season. Last week, he won the Stuttgart Open, which had propelled him to the top spot.
Federer suffered a shock defeat at Halle
Federer suffered a shocking 6-7 (6-8), 6-3, 2-6 defeat to Borna Coric at the Halle Open final. This loss brought an end to his 20-match win streak on grass. It not only cost him the number one ranking but also the opportunity to win his 99th career title. If Federer had won, he would have competed for his 100th career title at 2018 Wimbledon.
Halep retains the top spot in women's rankings
The Halle Open victory helped Borna Coric gain 13 places to his career best ranking of 21. Meanwhile, Marin Cilic, who won the Queen's Clubs, moved to the fifth spot after his victory over Serbian Djokovic. In the women's rankings, Simona Halep retained the number one spot despite not being in action last week.
