LONDON (LSE NEWS BY LONDON — Serena Williams is 41st birthday in a row and without a Grand Slam title since 2017, and after a traumatic first-round Wimbledon exit, she faces burning questions about her future.The American returned to Centre Court on Tuesday after a year out of singles tennis, but it was a miserable return to the scene of some of her greatest triumphs.The 23-time major champion was embraced as she entered the court and cheered through by a crowd eager to see her recapture former glory against unseeded Harmony Tan of France.In an uncharacteristically sloppy show that ended with a tame forehand dropped into the net, she appeared to be a pale shadow of her former self, making 54 unforced errors.

She fought for victory when she was 5-4 up in the draw and went into a 4-0 lead before losing in the tie-breaker.The American put a brave face on her loss to Aliaksandra Sasnovich, saying it was definitely better than last year, when an ankle injury forced a tearful exit in her first-round match.The 40-year-old only returned to tennis last week, partnering up with Ons Jabeur in the doubles at Eastbourne.When asked whether she might have played her final Wimbledon, she said she was uncertain.

Who knows where I'll be?Was asked if she'd be gratified if Wimbledon's defeat by 115th-ranked Tan was her last memory of the tournament, she replied: No.You know me.Yes, not at all.

Maybe tomorrow, I should have given more.Perhaps a week ago, I should have given more.Today was exactly what I could do, though.Wimbledon was won in 2002 by the former world number one, who was given a wildcard to compete at the All England Club.

She is firmly on the lookout for the US Open, which begins in August.Williamss' Grand Slam victory in 1999 was her first singles Grand Slam victory, launching her prolific career in the majors, which has seen periods of near-total dominance.The US Open, the first time I've won a Grand Slam, is always something that you should enjoy at home, said Williams, who has won at Flushing Meadows six times.Your first visit is always special.

Williams' place in the all-time greats' pantheon is now confirmed, but she is only one singles title behind Margaret Court's all-time Grand Slam record of 24.The American, who has also won major doubles titles with her sister Venus, last won a Grand Slam title at the Australian Open in 2017, giving birth to her daughter, Olympia, later that year.Since then, she has reached four Grand Slam finals, two at Wimbledon and two at the US Open, but has come up short each time.After retiring from the sport, Williams, who has 73 singles titles in her career, has dropped to 1,204th in the world.
