Pierce said she played the final match of her career against Li at the 2006 US Open. "Look where we are today," she said, looking at Li, seated to her right.

The 45-year-old Kafelnikov was described on his plaque as "one of the most dominant Russian players of his generation".

He captured the 1996 French Open and three years later won the Australian before claiming gold at the 2000 Olympics in Sydney. He also helped Russia win the Davis Cup in 2002.

"I know now what it is to be a Hall of Famer," he told the crowd. "I will carry that responsibility for the rest of my life, and hopefully I won't disappoint you."

"It means that I did it because of hard work," added the former world No 1. "All my success came because I did work hard."

Li, who now works as an ambassador for her hometown WTA tournament the Wuhan Open, expects to continue to play a prominent role in promoting tennis, despite her family commitments.

"It has been five years now since my retirement. Nowadays, I enjoy a better work-life balance, and most importantly I have two children. Also, the same husband," Li said with a smile.

"I will do all I can to inspire, to help more young and upcoming players and hope they can enjoy this amazing sport."
