A Grand Slam main draw holds 128 players. Most of them are there because their ranking was high enough on a date several weeks before the tournament started. The rest had to earn their place in a separate tournament held the week before, in front of small crowds on outside courts, with no ranking points on offer for anything except the final result. That tournament is qualifying, and it is governed by its own set of rules in the Official Grand Slam Rule Book.
How a player reaches a Grand Slam main draw
There are four routes into the 128-player field, and the rulebook sets out how many places each one is allowed. Direct acceptances make up the bulk of the draw. These are the players whose ranking cleared the cutoff, measured on a list dated roughly six weeks before the tournament begins.
Qualifiers come through the qualifying competition. Wild cards are placed in the draw at the sole discretion of the tournament, and the rulebook sets no limit on how many a single player may receive across a career. Lucky losers replace players who withdraw after qualifying has started.
The standard split is 104 direct acceptances, 16 qualifiers and eight wild cards. The rulebook also permits 108 direct acceptances with 12 qualifiers, or 112 with eight, so the number of qualifying places is not fixed across all four majors or all years.
The size and shape of the qualifying draw
Qualifying draws may hold up to 128 players, the same maximum as the main draw. Where 16 qualifying places are available, the draw is divided into 16 sections and the winner of each section takes one main-draw place. A 128-player draw therefore requires three wins to qualify. Smaller qualifying draws of 96 or 64 exist and follow the same sectional principle.
Seeding within qualifying
The qualifying draw is seeded, using the most recent available ranking list. Each section carries one seed on its top line and one on its bottom line, which is why the final round of qualifying so often pits two seeded players against each other for a single place.
Wild cards in qualifying
Qualifying draws carry their own wild cards, separate from the main-draw allocation. A 128-player qualifying draw allows nine, and draws of 96 or 64 allow eight. Tournaments may also run a separate playoff event to decide who receives them, and players who lose that playoff are not barred from entering qualifying by the ordinary route.
Why a player cannot pursue both routes
This is the provision that surprises people, and it shapes the decisions of every borderline player in the weeks before a major. The rulebook states that no player may be named as a wild card if they have competed in the qualifying competition of that same tournament.
A player ranked just outside the cutoff therefore faces a choice before either outcome is known. Entering qualifying guarantees a route in that depends only on winning matches, but it forecloses a main-draw wild card the moment the first ball is struck. Declining qualifying keeps the wild card possible and leaves the player with nothing if it does not arrive. Neither option can be reversed once qualifying begins.
Timing compounds the decision. Wild cards must be named at the moment the main draw is made, and a wild card who withdraws after that point cannot be replaced by another wild card. The vacancy goes instead to the next eligible player on the entry list, or to a lucky loser if qualifying has already started. A late withdrawal is only useful to a hopeful wild card recipient if it happens before the draw ceremony.
Lucky losers
A lucky loser is a player who lost in the final round of qualifying and enters the main draw anyway, replacing someone who withdrew. If more are needed than the final round supplies, players who lost in earlier rounds become eligible.
Selection is not purely by ranking. The four highest-ranked eligible players are drawn in a random order, and only after those four does the list follow ranking order. If there are more than two main-draw withdrawals when qualifying finishes, the random pool expands to match.
The obligations are demanding. A lucky loser must sign in with the referee at least half an hour before the first match of each day, and must be ready to play within five minutes of a default being announced in men’s events, or fifteen minutes in women’s events. A man who is not available when called drops to the bottom of that day’s priority list. A woman who is not available forfeits lucky loser status for the rest of the tournament.
Protected rankings and qualifying
Players returning from long absences may enter events using a ranking that reflects their standing before the absence. The ATP calls this entry protection and the WTA calls it a special ranking. It can be used for entry to a main draw or to a qualifying competition, but not for seeding on the ATP and not for lucky loser consideration on either tour, and its use is capped in both number of tournaments and elapsed time.
The practical consequence is that a protected ranking only helps if the protected number itself clears the cutoff of the draw the player is entering. A returning player whose pre-absence ranking sat outside the direct-acceptance cutoff will use the provision to enter qualifying rather than the main draw.
Rest between qualifying and the main draw
Qualifying is scheduled to finish no later than the day before main-draw play begins. Except in unusual circumstances, no player is required to start a first-round main-draw match until at least twelve hours after their final qualifying match ends. A player who has been made to play two qualifying matches in one day should not be scheduled the following day, unless they entered as a lucky loser.
These protections are why rain delays during qualifying week matter more than they appear to. A backlog does not simply move matches; it compresses the recovery window for the players least able to absorb the loss, who have already played three matches to reach a draw the direct acceptances entered fresh.
What qualifying is worth
Reaching a Grand Slam main draw is a substantial financial event for a player ranked outside the top 100, and first-round prize money at the majors has risen faster in recent years than the champion’s share. The rulebook also provides that a player who withdraws from the qualifying competition on site before their first match, having been declared unfit by the tournament doctor, may receive half of first-round qualifying prize money, subject to conditions including having competed in the preceding three weeks.
Frequently asked questions
How many matches must a player win to qualify for a Grand Slam?
Three, where the qualifying draw holds 128 players and 16 places are available. Smaller qualifying draws require fewer wins.
Can a qualifier be seeded in the main draw?
In practice this does not happen, because seedings are drawn from the top of the ranking list and a player ranked highly enough to be seeded would have entered as a direct acceptance.
Where are qualifiers placed in the main draw?
Qualifying places are positioned in the bracket when the main draw is made, before anyone knows who will fill them. The individual qualifiers are then drawn into those positions at random once the qualifying competition ends. No section of qualifying is tied in advance to a particular main-draw slot.
Has a qualifier ever won a Grand Slam?
Once in singles at the majors in the professional era, when Emma Raducanu came through qualifying to win the 2021 US Open without dropping a set.
Do qualifying matches earn ranking points?
Yes. Both tours award points for progress through Grand Slam qualifying, and reaching the main draw is worth considerably more than losing in the final round.
