Qualifying draws at professional tournaments are filled by players who chose to show up. That choice is economic, and it favors whoever had the shortest journey.
Qualifying is unpaid speculation
A player entering qualifying pays for flights, accommodation and his coach's costs with no assurance of reaching a main draw or earning anything meaningful.
A first-round loss in qualifying at a distant event can cost more than it pays, which makes each entry a wager rather than a fixture.
Players ranked outside the direct-acceptance range make these wagers constantly, and their season is shaped by which ones they can afford to lose.
Distance is the largest variable cost
Travel expense scales with distance while the prize structure does not, so the same tournament offers a very different risk to a local player and an intercontinental one.
A player living within driving range can enter cheaply, sleep at home and treat qualifying as low-risk. Someone flying across an ocean cannot.
Fields therefore fill with regionally based players, which is visible in the entry lists of events on every continent.
Wildcards concentrate the effect
Tournaments award a limited number of entries at their own discretion, and they commonly use them on players from the host country.
The rationale is commercial and developmental: local players sell tickets and the national federation often supports the event.
The consequence is that home players get chances that visiting players of similar ranking do not, compounding the geographic advantage already present.
Scheduling makes the gamble worse
Qualifying takes place in the days immediately before the main draw, so a player must arrive early and may leave before the tournament proper begins.
If he loses, the following week's event may be far away and its qualifying may already be under way, so a single defeat can waste two weeks.
Players manage this by planning routes through geographically clustered events, which again rewards those whose home region has a dense calendar.
The consequence is a distorted talent map
Regions with many professional events develop more professionals, because the cost of trying is lower there than anywhere else.
Players from regions with few events must relocate early, usually to Europe or the United States, or accept a structurally more expensive career.
Relocation costs money, so the sport's geography reflects where tournaments are held and which families can afford to follow them.
