Serena Williams' return to Wimbledon has not lasted as long as she would have hoped.

The 23-time grand slam singles champion has gone down to world number 113 Harmony Tan of France 5-7, 6-1, 7-6 in the first round.

The match lasted more than three hours.

The 40-year-old American had not played in singles since she was injured in the first round a year ago at the All England Club.

It was Tan's first ever match at Wimbledon - a victory over Williams on centre court.

"I'm so emotional. I don't know what to say because she's a superstar. When I was young watching her many times on the TV. For my first Wimbledon it's..wow," she said after the win.

More to come...
