Emma Raducanu says she feels a ‘lot lighter’ heading into the Australian Open, which starts in Melbourne on Sunday. The 21-year-old’s career has been plagued by injury since her miraculous victory at the US Open three years ago. Raducanu is on the comeback trail after being sidelined for eight months following surgery on both wrists and one ankle. After making her comeback in Auckland last week, Raducanu will return to grand slam action against Shelby Rogers of the US in the first round.
