Reem Abulleil takes a look at some of the important stats and figures entering this week's US Open.
The US Open commences on Monday with the top half of both the men’s and women’s draws in action, which means defending champions Rafael Nadal and Sloane Stephens will take to the court on opening day.
Known before 1968 as the US National Championships, the US Open is the second-oldest of the four Grand Slams after Wimbledon, and the only one to have been played each year since its inception in 1881.
First held in 1887, the US Open women’s singles championship is being staged for the 132nd time.
Here’s a look at some of the standout stats and figures ahead of the 2018 US Open.
0 – players in the Open Era have managed to win the US Open without dropping a set.
3 – matches lost by top-seeded Rafael Nadal in 2018 — the same number he lost in 2013 entering the US Open. Nadal is 40-3 this season and was 53-3 at the start of the 2013 US Open, where he won his 13th Grand Slam title.
6 – Roger Federer is targeting a sixth US Open title which would give him sole ownership of the top spot on the leaderboard of most trophies won here in the Open Era. He is currently in a three-way tie with Jimmy Connors and Pete Sampras with five.

13 – months since the ‘Big Four’ all competed at the same tournament. Their last reunion was at Wimbledon 2017. They finally reunite again at this US Open.
