• In 2008–2012, due to inclement weather conditions, the tournament lasted 15 instead of the scheduled 14 days, ending on the third Monday. In 2013, the schedule was extended to 15 days, potentially giving the players one more day to prepare for the final match. •
Maria Sharapova, 2006 champion, ranked third in the world (formerly first), withdrew from the tournament due to a shoulder injury. • In a second round match which pitted the
2001 and
2009 men's champions against each other,
Lleyton Hewitt defeated
Juan Martín del Potro in five grueling sets lasting over four hours; this marked the first time since he won the title in 2001 that Hewitt had defeated a top ten opponent at the US Open. • By winning the first set in her fourth round loss to
Victoria Azarenka,
Ana Ivanovic won her first set against a top ten opponent at a Grand Slam since she won the
2008 French Open, ending a streak of 15 consecutive sets lost against a top ten seed. •
Serena Williams won 24 consecutive games from 1–1 in the second set against
Sloane Stephens in the fourth round through to 1–0 in the second set against
Li Na in the semi-finals, breaking her own record of 23 games at
last year's US Open. • For the second consecutive year, Serena Williams and
Victoria Azarenka contested the women's final, marking the first time since 2001–2 in which two consecutive US Open finals were contested between the same two players. • By winning the tournament, both Rafael Nadal and Serena Williams collected the biggest payday in tennis history of $3.6M ($2.6M for the championship and an added $1M bonus for winning the
2013 US Open Series). Also, with the win, Williams and Nadal have now won each Grand Slam together – the Australian Open (2009), the French Open (2013), Wimbledon (2010) and the US Open (2013). They are the first male-female pair in the entire history of tennis, not just in the Open Era, to win all four Grand Slams together. • By winning the US Open,
Rafael Nadal became the first player since
Andy Roddick in 2003 to capture the 3 major consecutive US hardcourt season titles, namely the Roger's Cup, Cincinnati Masters and US Open. Note: :Ana Ivanovic retired in the second set of her fourth round match against
Venus Williams at
Wimbledon in 2009; thus, the losing streak of sets is 15. ==Point and prize money distribution==
