American great Serena Williams was unable to get past the first hurdle of her 2022 Wimbledon campaign, showing glimpses of her former dominant self but also a lot of rust in a 7-5, 1-6, 7-6 (10-7) defeat Tuesday to Frenchwoman Harmony Tan.

The 40-year-old Williams came into this year's Wimbledon with scant preparation, not having played any singles matches since her first-round loss at the All England Club last year, when she had to retire with a hamstring injury that lingered for several months.

She entered a grass tune-up event last week in Eastbourne, England, where she and doubles partner Ons Jabeur won two matches to reach the semifinals before having to withdraw due to a knee injury suffered by the Tunisian.

In Tuesday's final match on Centre Court, Williams - ranked No. 1,204 because of her lack of activity over the past year - was just a tad tentative on some of the biggest points.

With the 24-year-old Tan serving up set point in the first set at 6-5, ad-in, the American approached the net with a forehand that sat up and allowed her opponent to whip a forehand passing shot winner.
