Explained: What is protected ranking in Tennis and Badminton?

In elite sports, an athlete's ranking is their lifeblood. It determines which tournaments they can enter, whether they must play gruelling qualifying rounds, and who they face.

In racket sports like tennis and badminton, rankings are calculated on a rolling 52-week basis. If a player stops competing, their points naturally expire, causing their ranking to plummet.

To prevent a severe injury or pregnancy from unfairly destroying a player's career, governing bodies created the Protected Ranking system (known as "Special Ranking" in the WTA).

This mechanism acts as a competitive safety net, allowing elite athletes to return to the sport they love without starting from scratch.

How it works in Tennis (ATP & WTA)?

In tennis, the Association of Tennis Professionals (ATP) and the Women’s Tennis Association (WTA) allow players sidelined by long-term injury, illness, or pregnancy to freeze a version of their ranking.

Eligibility: A player must be out of competitive action for a minimum of six months.

The Calculation: The protected ranking is not simply the position the player held the day they got hurt. Instead, it is calculated using the average of the player’s official world ranking during the first three months of their medical absence.

The Duration: The length of protection depends on how long the player was out. If a player is absent for 6 to 12 months, they can typically use their protected ranking for 9 tournaments. If they are out for more than a year, that protection extends up to 12 tournaments (or up to 12 months from their return date).

It is this protected ranking that helped India’s Karman Kaur Thandi earn a spot at the 2026 French Open women’s singles qualifying draw.

How it works in Badminton (BWF)?

The Badminton World Federation (BWF) employs a highly similar protocol to safeguard its athletes. If a badminton player or doubles pair suffers a long-term injury or illness, they can formally petition the BWF for a Protected World Ranking.

Eligibility: Much like tennis, the athlete must be unable to compete for a minimum continuous period of six months, up to a maximum of two years.

The Calculation & Use: The BWF freezes the player's ranking from the date of their last entry or when the injury occurred. Upon returning, the player can use this frozen status to enter high-tier BWF World Tour events (like Super 500, 750, or 1000 tournaments) that they would otherwise be locked out of due to their dropped active ranking.

At the India Open Super 750 earlier this year, India's Malvika Bansod returned to action after from injury with protected ranking.

Entry, not seeding

The most crucial distinction of a protected ranking across both tennis and badminton is its limitation: it is used strictly for tournament entry, never for seeding.

For example, if a former World No. 5 tennis player returns from an injury using a Protected Ranking of No. 5, they are guaranteed a spot in the main draw of a Grand Slam. However, because their actual active ranking might be No. 600, they will enter the tournament unseeded. This means they could realistically draw the current World No. 1 in the very first round.

Why it matters?

Without protected rankings, returning stars would be forced to play in low-level Challenger or International Challenge events just to scrape together enough points to climb back up.

This system protects the financial livelihood of the players, maintains the star power of major tournaments, and ensures fairness. It honours a player's historical merit, ensuring that a medical setback does not completely erase years of hard work.
