Serena Williams proved that time has done little to dull her competitive edge. Four years after her last professional match at the 2022 US Open, the 44-year-old American made a winning return to the tour, partnering 19-year-old Canadian Victoria Mboko in doubles at Queen's Club in London.

The unlikely pairing, separated by a quarter century, defeated third seeds Nicole Melichar-Martinez and Erin Routliffe 7-6(2), 6-2. A result that sent shockwaves through the London grass courts and thrilled the capacity crowd who had gathered to witness the legend's return.

Serena Williams showed from the very first game that her greatest weapon remains intact. Her serves, clocked at up to 120 mph, wreaked havoc on the opposing side. The first set went to a tiebreak where Williams and Mboko conceded just two points. The second set was a masterclass, the duo finding an impressive rhythm to close out 6-2.

After the match, the holder of 23 Grand Slam singles titles said she had "nothing to prove." A champion's statement that belied the fierce competitiveness visible in every forehand and every net approach during this opening round. The partnership with Mboko, ranked ninth in the world in doubles, offers a fascinating blend of experience and youth.

The question now buzzing around the tour is straightforward: is this doubles comeback a prelude to a singles attempt? Williams has not shut the door, keeping the suspense alive as Wimbledon draws ever closer. For now, the Williams-Mboko duo's next challenge at Queen's Club already promises another exceptional tennis moment.
