For the first time during the two weeks of the US Open, anyone and everyone will have a chance to watch the world’s toughest tennis free of charge – live and in person.

The 2015 US Open will be offering free grounds admission to fans on the event’s second Thursday, Sept. 10. The day’s action will be filled with play in men’s, women’s and mixed doubles – including semifinal action in men’s and women’s doubles – as well as junior and wheelchair competition and the semifinals of the Champions Invitational, a showcase of former Grand Slam tournament champions or finalists.

The free grounds admission will also enable fans to watch the second year of the American Collegiate Invitational, which features the top American collegiate tennis players facing off for a potential wild card into the 2016 US Open or 2016 US Open Qualifying Tournament.

Play will begin at 12 p.m. ET, with the gates opening at 11 a.m.

Fans are also invited to stay to watch the evening’s women’s singles semifinals, scheduled to begin at 7 p.m. ET, on the video screens throughout the grounds. A purchased ticket is necessary to gain access to Arthur Ashe Stadium for the women’s semifinals. (There will be no play in Arthur Ashe Stadium during the day.)

The free grounds admission was made possible by a change in the schedule for the 2015 US Open. This year, the Open is returning to a 14-day plan, with a day of rest between the men’s and women’s singles semifinals and finals. That means the final four days of the event will feature the women’s semifinals Thursday night, the men’s semifinals Friday, the women’s final Saturday afternoon and the men’s final Sunday afternoon.
