Governing body officials have repeatedly defended the shift, arguing it aligns Masters events with the WTA’s equivalent 1000-level tournament structure, increases overall prize pools by an average of 35% across events, and delivers more content for broadcast partners and in-person fans. However, 20-year-old French rising star Arthur Fils became the latest high-profile player to publicly denounce the model during his pre-tournament press conference at the 2024 Rolex Monte-Carlo Masters, joining a growing cohort of athletes who argue the format places unnecessary physical and mental strain on players while offering disproportionate benefits only to the highest-ranked tour members. For top 20 players, who receive automatic byes into the second round of main draws, the two-week format adds just one extra rest day between matches, but for competitors ranked between 30 and 150, who are often required to compete in 3-round qualifying draws before the main event begins, the format can add up to 4 extra matches to their monthly schedule if they advance deep into a tournament. Fils, who reached a career-high ranking of world No. 19 in 2024, noted that younger players in particular face disproportionate risk: “Most of us in the 18 to 22 age bracket don’t have the sponsorship deals that let us skip events to recover if we’re tired. We have to play every possible tournament to earn enough points to stay in the top 100, qualify for Grand Slams, and make a living. This two-week structure means we’re playing 20 to 25 more matches a year than we were 3 years ago, and the injury numbers are going up to match.” He also pointed out that the compressed schedule between two-week Masters events and consecutive Grand Slams leaves players with almost no time to adjust surfaces or recover ahead of the sport’s most high-profile tournaments, citing the 10-day gap between the end of the two-week Rome Masters and the start of the French Open as a particular pain point for clay-court specialists. Fils called on the ATP to hold formal votes with player representatives before rolling out additional two-week events, and to increase prize money for qualifying rounds and early main draw matches to compensate lower-ranked players for the extra physical load.
