The US Open Qualifying Tournament will expand from four days to five in 2019, beginning this year on Monday, Aug. 19, and concluding on Friday, Aug. 23. The move to a five-say event will allow for greater flexibility in scheduling, and allow for more scheduling windows in case of inclement weather that week.

The US Open Qualifying Tournament will once again feature 128 men and 128 women competing for a spot in the Open’s main draws. Each of the men’s and women’s draws annually includes 16 qualifiers, who must win three matches in Qualifying to advance. The US Open Qualifying Tournament is itself the fifth-largest tennis tournament in the U.S., offering a whopping $3 million in total prize money.

The Qualifying Tournament is, of course, the centerpiece of US Open Fan Week, which once again features a variety of events and activities at the USTA Billie Jean King National Tennis Center that are free and open to the public. The full slate of US Open Fan Week activities will be announced at a later date.

US Open main-draw play begins on Monday, Aug. 26, wrapping up on Sunday, Sept. 8, with the men’s final.
