Stuttgart: Roger Federer staged a 6-7 (2-7), 6-2, 7-6 (7/5) comeback on Saturday over Nick Kyrgios to reach the Stuttgart Cup final and take back the World No.1 ranking.

The 36-year-old Swiss will resume his place at the top of the ATP rankings for the sixth time in his career on Monday, beginning a record 310th week at the summit of the men’s game.

His upward move will leave Rafael Nadal on second as the countdown to Wimbledon intensifies with a fortnight left prior to the start of the grasscourt major.

Top seed Federer will play for the 98th title of his career on Sunday against Milos Raonic.
