Williams, ranked eighth in women's tennis going into the US Open and turning 39 this month, has already won the most US Open singles matches in history. Three-year-old Olympia is there to watch her mom go for her 24th grand slam title to tie Margaret Court's overall record.
"I just have a totally new respect for moms," Williams said, according to NBC Sports. "I would never have thought I would be playing as a mom." She continued on to say that the "plus" is that one day her daughter can look back and know she was in attendance watching.
