Roger Federer begins his search for a sixth US Open men's singles title on Tuesday, when he faces Yoshihito Nishioka to open the night session in Arthur Ashe Stadium. It will be Federer's 81st career match inside the biggest tennis stadium in the world, more than any other male player in history. pored over the record books, daily draw sheets, schedules and almost two decades of archived umpire scoreboards to find 50 other interesting facts, unknown stats and US Open Federer minutiae.

1. Federer has won five US Open men’s singles titles, tied for fourth all-time among male players and tied with Pete Sampras and Jimmy Connors for the most in the Open era.

2. No player, man or woman, has won five consecutive championships in New York, in the Open era other than Federer, who did so between 2004-08. Chris Evert was closest, with four between 1975-78.

3. Federer owns a career 82-12 record in 17 trips to New York. He trails only Jimmy Connors (98) in men’s singles matches won at the US Open.

4. Federer has played 72 different players in the main draw of the US Open, including 16 players multiple times. He’s faced Novak Djokovic six times (3-3), as well as Lleyton Hewitt (3-0) and Andre Agassi (2-1) three times each.

5. The only player Federer has played multiples times and never beaten is Juan Martin del Potro. He lost to the Argentine in the 2009 final and the 2017 quarterfinals. Only one other player has defeated Federer multiple times at the US Open: Djokovic in 2010, 2011 and 2015.

6. Federer has played 18,952 points at the US Open, winning 10,463 of them. That means that one of the greatest players of all time has lost almost 45 percent of the points he’s ever played in New York.

7. The longest game Federer has played in terms of number of points was an epic 26-point, 12-minute game against James Blake at the 2003 US Open. With Federer leading one-set-to-love and the second set on serve at 1-1, Blake saved eight break points in a 10-deuce game to earn a hard-fought hold. Nonetheless, Blake went on to drop the set in a tiebreak en route to losing the match in straight sets. Federer’s 20 unconverted break points fall short of the record set by Cedric Pioline, who was 7-for-35 in the 1993 US Open in a four-set win over Andrei Medvedev. The ATP kept tracking such stats from 1991.

8. The Swiss has won more US Open titles (five) than he has lost matches in straight sets (four) at Flushing Meadows.
