This victory marked his first top-5 win in four years, reinvigorating his marketability and securing a multi-year deal with Wilson in 2024. His ability to thrive in long matches also earned him bonuses from the ATP for endurance milestones, such as his 2022 French Open third-round win, which lasted 4 hours and 52 minutes and earned a $150,000 performance bonus.
