A player can be ranked among the world’s best and still need to win three matches just to reach the US Open main draw. That short, high-pressure tournament is the qualifying event: a separate singles draw in which players compete for a limited number of places at Flushing Meadows.
Here’s how entry, scoring and qualification work—and why a player who makes it through qualifying can be a dangerous opponent once the main event begins.
How many players qualify for the US Open?
The US Open holds a 128-player qualifying draw for men’s singles and a 128-player qualifying draw for women’s singles. In each draw, 16 players earn places in the main draw. Qualifying is single elimination, so a player must win three matches in a row to get through.
The main draw also has 128 places in each singles event. Its usual allocation is 104 direct acceptances, 16 qualifiers and eight wildcards. If a player withdraws, a lucky loser from qualifying may take the vacant place instead.
| Route into the singles main draw | Usual number of places |
|---|---|
| Direct acceptance | 104 |
| Qualifying | 16 |
| Wildcards | 8 |
| Total | 128 |
These are the standard allocations; withdrawals and replacement procedures can affect who ultimately fills a spot. Qualifying is a singles pathway. Doubles has its own entry process rather than the same three-round qualifying draw.
Who can enter qualifying?
Qualifying is not an open tournament where anyone can turn up and sign in. Players apply through the relevant professional tour entry system, and places are assigned under tournament entry rules. Rankings are central: players with stronger rankings generally have priority for available spots. The exact entry list depends on the applicable ranking date, deadlines and withdrawals.
Some places may be awarded as qualifying wildcards. These let the tournament admit selected players who would not otherwise make the qualifying list—for example, a promising young player or a local competitor. A wildcard for qualifying is not the same as a wildcard into the main draw: the qualifying wildcard recipient still has to win three matches to earn a place.
Players who are already accepted directly into the main draw do not need to play qualifying. Nor does a high ranking guarantee a main-draw spot if a player falls outside the direct-acceptance cutoff; that player may have to enter qualifying, depending on the entry rules and available places.
How qualifying matches are scored
Both men’s and women’s qualifying singles matches are best of three sets. This is an important difference from the US Open men’s main draw, where matches are best of five sets. Women’s main-draw singles is also best of three.
Games use standard advantage scoring. If a set reaches 6–6, a tiebreak decides it. In the first or second set, that is a standard tiebreak played to at least seven points, with a two-point margin. If the deciding set reaches 6–6, players play a 10-point match tiebreak, again needing to win by two.
That format makes the last stages of a close match especially tense. A player can be one point from losing a long deciding set, then turn the match around in a short tiebreak. There is no extra set beyond the third.
What happens after a player qualifies?
Winning the third qualifying round earns a place in the main draw; it does not guarantee a particular opponent or an easy first-round match. Qualifiers are placed into the main draw through the tournament’s draw procedures and may meet a seeded player—or another qualifier—early.
Qualifiers have already played three competitive matches, which can help them settle into the courts and conditions. The trade-off is that they have also spent more time on court and may be carrying fatigue. For men, the jump from best-of-three qualifying to best-of-five main-draw matches is another challenge.
Emma Raducanu showed just how far that route can lead. In 2021, she won all three qualifying matches and then seven more in the main draw to claim the title, becoming the first qualifier to win a Grand Slam singles title in the Open Era. Her run was exceptional, but it also shows that “qualifier” describes how a player entered the draw—not the level they can reach once they get there.
What is a lucky loser?
A lucky loser is a player who loses in the final qualifying round but later gets into the main draw because another player withdraws. It is not a place awarded for a strong performance alone: there must be an opening in the main draw, and the player must meet the event’s sign-in and selection requirements.
Lucky-loser selection follows the tournament’s priority rules, which generally take ranking into account. A player who loses in an earlier qualifying round does not normally qualify for a lucky-loser place while final-round losers are available. If you are following a particular player, check the official US Open draw and entry updates, since withdrawals can change the list close to the start of play.
What fans should watch for
Qualifying often features players trying to break into the tour’s top tier alongside established professionals working their way back from injury or a ranking slump. Because every match is an elimination match, the stakes are immediate: one difficult service game or a missed opportunity in a tiebreak can end a player’s US Open campaign before the main draw begins.
For a simple guide while watching, remember three things: the winner needs three match victories, each match is best of three sets, and only 16 players from each singles qualifying draw advance. The final round is the most direct route to the main event, while the lucky-loser list offers a narrow second chance if withdrawals create one.

Final Thoughts
US Open qualifying is a compact tournament with a clear prize: win three best-of-three matches and earn a place in the 128-player singles main draw. Rankings determine much of the entry order, wildcards provide additional opportunities, and lucky losers can step in if withdrawals leave an opening. For fans, it is also a chance to spot players on the rise—and to see just how much pressure can fit into a single match.
