Rune suffered an Achilles tendon rupture in October 2023 while leading Ugo Humbert by a set, but he returned to the top 10 in the world rankings days after the injury, according to reports. He is currently ranked 29th globally and is a three-time Grand Slam quarter-finalist. The exact date of his Achilles surgery in October 2023 remains unclear, and it is unknown whether he will participate in the Masters 1000 event in Rome in early May 2024.
Meanwhile, Valentin Vacherot, a 27-year-old Monegasque player, scored an upset win at the Monte-Carlo Masters on Wednesday, defeating world number five Lorenzo Musetti 7-6(6) 7-5, as reported. This victory marked his second career win over a top-five player, and he is the second Monegasque to reach the Monte-Carlo Masters third round, following his half-brother and coach Benjamin Balleret, sources indicate. Vacherot previously defeated Novak Djokovic en route to his maiden ATP title at the Shanghai Masters in 2023.
The Hamburg Open will also feature world number three Alexander Zverev, and the French Open is scheduled from 24 May to 7 June 2024. The ranking points or implications for Rune's return at the Hamburg Open have not been specified.
