How many hours of tennis were played in Arthur Ashe Stadium on Day 10 of the 2026 US Open?
Answer
13 hours 47 minutes
Arthur Ashe Stadium hosted 13 hours and 47 minutes of tennis on Day 10 of the 2026 US Open.
The unusually long day resulted from all four quarterfinal matches going to a deciding set. Three of those matches also went to match tiebreaks, extending the schedule and keeping the main stadium active for much of the day.
Arthur Ashe Stadium is the largest venue at the USTA Billie Jean King National Tennis Center in New York. It is the US Open’s principal show court and hosts the tournament’s biggest matches, including the singles finals.
A deciding set does not automatically mean a match tiebreak in every competition. Grand Slam rules and event formats determine how a final set is resolved, which is why the day’s match-tiebreak total is a useful detail rather than a general rule for all tennis.
