While walking with her beloved yorkie, Chip, on Sunday night in San Francisco’s Mission Dolores Park, the Australian Open champ stumbled upon two men playing against each other, the New York Post reports. “I think they’re in the middle of playing out points, but I’m going to ask them if I can have the winner,” Williams shared with her social-media followers as an unseen man – apparently her fiance, Reddit co-founder Alexis Ohanian – kept the camera trained on the 23-time grand slam champ.
