World tennis superstar Serena Williams from USA has withdrawn from the elite WTA Finals in Singapore.
According to her, she’s still working to recover from the shoulder troubles that hindered her in 2016.
The WTA announced Williams’ withdrawal from the event.
Williams claimed just one Grand Slam title in 2016, at Wimbledon. After that, shoulder troubles hampered her in Rio where her hopes of a fifth Olympic gold medal were crushed in the third round.
The 22-time Grand Slam champion pulled out of two tournaments in China after being knocked out of the semi-finals of the US Open.
