Top Seeds Grapple with Issues as 139th Wimbledon Championships Begin Monday

The 139th Wimbledon Championships begin Monday in London, and both top seeds are arriving with serious health questions. Men's top seed Jannik Sinner, the defending champion, has not played a competitive grass-court match since a frightening physical collapse at the French Open. Women's top seed Aryna Sabalenka is working through form issues after getting bageled in Berlin just weeks ago.
The tournament carries a record prize pool of £64.2 million, according to Flashscore. More than 500,000 fans are expected at the All England Club over the fortnight. For the first time in its 149-year history, Wimbledon will also allow players to challenge judgment calls using video review technology on six show courts.
Sinner's road to SW19 was rocky. At Roland Garros in late May, he suffered what reporters called a "physical collapse" — severe nausea and cramping — during a second-round loss. He then underwent intensive medical testing in Milan and Turin. Betting markets still list him as the heavy favorite at -180 odds, according to Sports Betting Dime.
Sinner told reporters this week: "All tests were really good... physically I'm in a very good place," according to Tennis365. But former US Open finalist Andy Roddick pushed back. He said Sinner's lack of any competitive grass matches since the collapse creates a "massive opening" for the rest of the field.
Sabalenka enters as the women's favorite, but her grass-court prep has been uneven. In Berlin, Jessica Pegula bageled her in the third set of their semifinal. Sabalenka downplayed the result, saying: "I don't want to stay too much in those numbers... things are clicking back together," according to Win 98.5.
World No. 2 Elena Rybakina is also a concern. She withdrew from Bad Homburg citing "right hip discomfort" after winning just one match across her first two grass events, according to Pro Football Network. Despite that, Rybakina has a live mathematical path to World No. 1. Because Sabalenka is defending 975 ranking points from her 2025 semifinal run, a deep Rybakina run could flip the top spot.
Last year's Wimbledon set an Open Era record: eight Top 10 seeds lost in the first round alone. Analysts have since called it the "2025 Bloodbath." In total, 36 seeds failed to get past the second round, according to Forbes. That result has reset expectations entering 2026. Being seeded no longer means being safe on grass.
Analyst Jon Wertheim of Sports Illustrated argues the gap between the Top 5 and the rest of the Top 50 has "effectively closed" on grass. He points to a lack of surface-specific prep time as the main driver. Novak Djokovic enters seeded 7th — his joint-lowest Grand Slam seeding in eight years — according to Radio Times.
Serena Williams, 44, is back at Wimbledon on a wild card. It is her first singles appearance since 2022. She said her "expectations are definitely different for the first time" in her career, according to Field Level Media. Some see it as a farewell tour. Others note she won two grass-court doubles matches in the lead-up and call her a "genuine landmine" in the draw.
British fans are watching Emma Raducanu and Jack Draper closely. Raducanu, seeded 30th and the highest-ranked British woman, is managing a "lower-leg niggle" she picked up after reaching the Queen's Club final, according to The Guardian. Draper is unseeded after a year of injuries. Defending champion Iga Swiatek, the women's No. 3, said she is "keeping expectations low" and still needs to "adjust" to grass, according to Flashscore.
