Four Points

🎾 Which Sinner: The question on everyone’s mind today is: Which Jannik Sinner will arrive on the court today against Ben Shelton? The number one player in the world was lucky to escape his previous match when Grigor Dimitrov collapsed to the ground with a pectoral injury. Lucky because he had his own injury from falling in the first set. The Italian was set to have an MRI on his elbow on Tuesday and reportedly had just a 20-minute hitting session later in the day.

🎾 Qualified: The year is only half over, but Aryna Sabalenka has been so incredibly dominant in 2025 that she has already qualified for the WTA Finals in Riyadh after defeating Laura Siegemund in three stressful sets of tennis. With 47 match wins this year, she has earned 6,615 points in the race to the WTA Finals — more than 2000 points ahead of her closest competitor, Coco Gauff.

🎾 Change of heart: Has Iga Swiatek had a change of heart on the grass? Coming into Wimbledon, she seemed to have made a shift in her overall mindset on the court that was lacking throughout the clay season. But she’s also hitting the ball cleaner on the faster, skiddier surface than she has in previous years. Could this be the year for a run to the final? Why not? The draw is more open than ever. But she’ll have a real test against Liudmila Samsonova, who took out a few top players in Berlin.

🎾 Finito: In an emotional press conference at Wimbledon, Fabio Fognini calls it a career.
