British number one Jack Draper was forced to retire from his Japan Open quarter-final match against Ugo Humbert after struggling with an abdominal injury. Draper, ranked 20th in the world, lost the first set 7-5 and was trailing 2-1 in the second when he took a medical timeout to receive treatment. Despite attempting to continue, the 23-year-old was unable to finish the match.
Humbert advances to the semi-finals, where he will face Czech Tomas Machac for a place in the final.
Draper’s injury raises concerns after his recent health struggles, including vomiting during his US Open semi-final loss to Jannik Sinner and experiencing sickness after his Australian Open first-round victory in January, which he attributed to “psychological stress.” It remains unclear if the abdominal issue in Tokyo is related to these past incidents.
Meanwhile, Denmark’s Holger Rune has set up a semi-final clash against either Arthur Fils or Ben Shelton after defeating Japan’s Kei Nishikori 3-6, 6-2, 7-5.
In Beijing, world number three Carlos Alcaraz cruised into the China Open quarter-finals with a 6-1, 6-2 win over Tallon Griekspoor, setting up a clash with Russia’s Karen Khachanov.
