Serena Williams beaten by Harmony Tan in Wimbledon thriller

Serena Williams was unable to summon the old magic as her Wimbledon return ended in a first-round defeat to little-known Frenchwoman Harmony Tan.

Playing singles for the first time since leaving Centre Court in tears after a hamstring injury in the opening round 12 months ago, Williams was rusty and prone to errors.

The will remained and, cheered on by a supportive crowd, she looked like she might stumble over the finish line after coming from a set down and then saving a match point in the 12th game of the decider.

Tan, 24, a debutante ranked 115th, is the type of player Williams used to beat before stepping on court, but no one, probably including herself, knew what to expect here.

Williams, 40, was extremely rusty in the first two games, her footwork leaden and her ball-striking wayward, but she gradually began to find some rhythm.

She was particularly vocal, shrieking at every winner and error, and it worked as she moved into a 4-2 lead.

But the main question mark was always going to be around Williams’ fitness, and she was puffing hard as Tan eventually broke back after a long service game.

Williams had a chance to draw level and force a tie-break but looked anxious and was unable to convert as Tan moved ahead.
