Seven-time Wimbledon champion Serena Williams suffers shock first-round defeat in a late-night epic

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 on Centre Court.

Stepping out on court to play singles for the first time since leaving the big stage prematurely and in tears after

suffering a hamstring injury in the opening round 12 months ago, Williams was rusty and error-prone.

The will remained and, cheered on by a supportive crowd, she looked like she might stumble over the finish

after coming from a set down and then saving a match point in the 12th game of the decider.

But instead Williams suffered just her third first-round loss at a grand slam, going down 7-5 1-6 7-6 (10-7)

in a deciding tie-break at 10.35pm after three hours and 10 minutes.

At 40, the American's time in the game is clearly running out, but she remained vague about her future plans and refused to rule out another tilt at Wimbledon next year.
