You may be able to still get tickets for the complex, where they have big screens. That is you will be watching it next to the stadium but not inside, only on the screens. You may also be able to sneak in at the very end when people start to leave. Good luck.
Can watch from outside on big screens
US Open does not sell ground passes for the final 5 or 6 days of the tournament. So the only way you'll be able to enter the grounds is with an Arthur Ashe ticket
