Serena Williams plans to retire or in her words evolve away from tennis after the US Open, which begins this month.

The 40-year-old has won 23 grand slam singles titles, one shy of Margaret Court's all-time record.

She plans to develop Serena Ventures, a venture capital firm, and expand her family.

Former Tennis Player and Commentator Belinda Cordwell joined Heather du Plessis Allan Drive to discuss Serena Williams departure from the sport.
