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 Swiss will resume his place at the top of the ATP rankings for the sixth time in his career tomorrow, 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 today against Milos Raonic. The Canadian hammered 19 aces to eliminate defending champion Lucas Pouille 6-4, 7-6 (7/3).
