Switzerland's Roger Federer remained at the number one spot with 10,060 points, exactly 600 points ahead of World No.2 Rafael Nadal of Spain, in the men's Association of Tennis Professionals world singles rankings released on Monday.
Last month, the 20-time Grand Slam champion reclaimed the top spot for the first time since October 29, 2012 when he overtook Nadal, following his victory at the Rotterdam Open, reports Efe.
The top two players were still far above the competition, as World No. 3 Marin Cilic of Croatia was nearly 4,600 points behind Nadal, narrowly ahead of Bulgaria's Grigor Dimitrov and Germany's Alexander Zverev.
Outside the top ten, Spain's Roberto Bautista Agut moved up seven spots to 16th after winning his first Dubai Championships title on Saturday, his second title this season.
