JOLLY ROGER BACK ON TOP

ROGER FEDERER snatched back the world No.1 slot by coming from behind to beat Nick Kyrgios 6-7

6-2 7-6 in the semi-finals of the ATP Mercedes Cup in Stuttgart.

Federer, 36, (right) knew he had to win to topple Rafa Nadal off the top of the rankings.

And his 15th successive win on grass means he will play Canada’s Milos Raonic in today’s final. But he was made to work hard by Kyrgios, 23, who was playing in his first tournament after two months out with an elbow injury. Federer conceded the first set on a tie break but fought back to level and was then taken all the way in the third.

Raonic beat defending champion Lucas Pouille 6-4 7-6 in the other semi.
