Aryna Sabalenka's coach details her journey from serving struggles to world No. 1 status

Aryna Sabalenka's coach revealed she overcame significant serving issues that led to 428 double faults in 2022. After hiring biomechanics specialist Gavin MacMillan, her performance improved, resulting in three Grand Slam titles and her current status as world No. 1. Sabalenka's turnaround began in late 2022, with MacMillan helping her correct her serving technique. Their work quickly paid off, as she won her first Grand Slam title shortly after their collaboration started. Now heading into the WTA Finals as the top seed, Sabalenka reflects on her journey. She empathizes with other players facing similar challenges, like Coco Gauff, and believes they can also overcome serving difficulties.
