Serena Williams: Former world No 1 adds the Berlin Tennis Open to her comeback schedule, starting at Queen's Club

Serena Williams, 44, has announced a comeback to professional tennis, beginning with the HSBC Championships at Queen's Club in London where she will play doubles alongside Canadian teenager Victoria Mboko. She has also been confirmed for the Berlin Tennis Open starting June 15, though her doubles partner for that event is yet to be announced. The scheduling of both grass-court events has raised speculation that Williams may be targeting a return at Wimbledon.
