After nearly four years away from professional tennis, Serena Williams made a winning return at Queen's Club on Tuesday.

The 44-year-old Williams showed she still has plenty of her trademark power, hitting service winners as she teamed up with 19-year-old Canadian Victoria Mboko to win their opening doubles match at the grass-court tournament.
