Tough break at the US Open—three more men’s singles players, including Cobolli and Altmaier, retired mid-match due to injuries, pushing the total to seven withdrawals this year. Meanwhile, the ageless Novak Djokovic powered through his own back issue to reach the fourth round, tying Jimmy Connors’ record as the oldest man to do so at 38. Is the grind of five-setters catching up with the field, or just bad luck this year? #Sports #Tennis #USOpen
