AT 34, Serena Williams is old for a tennis champion. The cartilage in her knees has started to wear away, so the bones rub against each other when she runs. In June, she lost the French Open final to a relative newcomer, 22-year-old Spaniard Garbiñe Muguruza, after struggling with a thigh injury. At this stage in a career, most professional players retire, at peace with the idea that they can’t continue competing for Grand Slam titles.
SLAM-FEST : Williams has been on a phenomenal run since hiring Mouratoglou as her coach.
