11 September 2017 marked one of Spanish tennis' greatest achievements; it was the first day that both the men's and women's world number one have been from Spain.
Rafa Nadal cemented his position as the number one men's tennis player on Sunday after he beat Kevin Anderson in straight sets to win the US Open.
He now sits almost 2000 points above all-time Grand Slam record holder, Roger Federer, who sits second in the ATP world rankings.
Recently joining Rafa at the very top of international tennis is Garbiñe Muguruza. On Monday, Garbiñe shot to the top of the women's singles rankings issued by the WTA, ahead of Romanian Simona Halep. Now, for the first time in history, two Spaniards sit at the pinnacle of the game.
Only two other countries have managed this in the past. Jimmy Connors, John McEnroe, ChrisEvert and Martina Navratilova all from the US, coincided as world number ones. Also, Germans Boris Becker and Steffi Graff sat together at the top of world tennis in 1991. The last two players from the same country to lead the world tennis classifications were Serena Williams and André Agassi from the US. Now, Spain's Nadal and Muguruza join these tennis legends at the forefront of the game, a remarkable achievement for Spanish tennis.
