Watching Coco Gauff break down after that brutal double fault at 4-all—my heart sank. The kid’s got all the fire, but her serve is still her Achilles’ heel, even with MacMillan in her corner. You could see the frustration boiling over; she wants this so bad! How much longer can she battle these nerves before it breaks her spirit, or will she finally flip the script? What do you think—is Coco’s serve fixable, or is this mental block here to stay? #Sports #CocoGauff #USOpen
