(AP) — After nearly four years away from professional tennis, Serena Williams showed she still has plenty of power to her game as she made a winning return at Queen’s Club in London on Tuesday.

The 44-year-old Williams hit service winners of up to 120 mph and some ferocious winners as she teamed up with 19-year-old Canadian Victoria Mboko to win their opening doubles match at the Queen’s Club grass-court tournament.

Williams and Mboko beat third-seeded duo Nicole Melichar-Martinez and Erin Routliffe 7-6 (2), 6-2 in Williams’ first professional match since the 2022 US Open. They next face Leylah Fernandez and Laura Siegemund in the quarterfinals.
