PARIS: Former US Open champion Juan Martin Del Potro climbed two places to sixth in the ATP rankings released on Monday after he defeated Roger Federer in the Indian Wells final.
The 29-year-old handed Federer his first defeat of 2018 with a 6-4, 6-7 (8/10), 7-6 (7/2) victory on Sunday, extending his own win streak to 11 matches including a title run earlier this month at Acapulco.
Federer himself reclaimed top spot just a month ago and remains marginally ahead of his eternal Spanish rival Rafael Nadal, who missed the American tournament with a leg injury.
