Seven-time Wimbledon Champion Serena Williams stunned second seed Anet Kontaveit on Wednesday to reach the third round of the US Open. Williams has announced the tournament will be her last before retiring from tennis but it would seem he has no intention of ending her career without a fight.

The 23-time Grand Slam champion, who turns 41 next month, had to dig deep after winning a close first set. Williams then seemed to suffer a dip in energy in the second before rallying to win the match in three sets 7-6 (7-4) 2-6 6-2.

The Arthur Ashe Stadium was full of A-list celebrities including Gladys Knight and Tiger Woods. The attention demonstrates the impact the American has had over her illustrious career.

Due to her absence from the court in recent years due to injury, the former World No 1 is now remarkably ranked 605^th in the world rankings. However, there is no doubt Williams is still a force in the woman’s draw and will be determined to stay in the tournament for as long as possible.
