A last-16 US Open finish and a first ATP Tour final have made 2023 Jack Draper's most successful year of his young career so far.
But for the 21-year-old Briton, success has been tinged by sadness with his grandmother - a former tennis player and coach - unable to recognise his achievements.
Draper's grandmother has Alzheimer's disease, a condition that causes dementia and the gradual decline of cognitive functioning in the brain.
Draper, the latest 'Sports Champion' to join the Alzheimer's Society in hope of raising awareness of the condition, described it as a "cruel disease" which has had a "devastating" effect on his family.
