Rafael Nadal extended his lead at the top of the world rankings after claiming his 16th Grand Slam title at the US Open, while Roger Federer took second spot from Andy Murray. Spaniard Nadal and 19-time major winner Federer sit first and second on the all-time Grand Slam champions list, but it is the first time they have occupied the top two places in the rankings since 2011. Nadal, 31, had retaken the world number one spot from Murray the week before winning his third US Open title, and now holds a substantial lead over reigning Australian Open and Wimbledon champion Federer. Swiss legend Federer, 36, was out of sorts in New York and lost to Juan Martin Del Potro in the last eight. Murray missed the final major tournament of the season with a hip injury.
