Three-times Grand Slam quarter-finalist Holger Rune will return to action at next month’s Hamburg Open after having Achilles surgery in October, tournament organisers said on Thursday.
Rune suffered the season-ending Achilles tendon rupture in the Stockholm Open semi-finals when he was up a set against Ugo Humbert. Days later, he returned to the top 10 in the world rankings despite losing out on a second title of the year.
