Serena started this tournament seeded eighth and for once on the opposite side of the women's singles tourney bracket from Venus.
Rivalry? What rivalry?
Serena then had to do three sets of work in the second round against fellow American Caty McNally.
The wild card qualifier McNally captured the first set 7-5. Little Sis stepped her game up another level to take the next two sets and punch her ticket to the third round with a hard fought 5-7, 6-3, 6-1 win
Little Sis once again handled her tennis business, nothing another straight set 6-3, 6-4 win to push her into the US Open quarterfinals against 18th seeded China's Wang Qiang.
If she gets past this quarterfinal match, she would face the winner of the Elina Svitolina- Johanna Konta match in the semis with a spot in the US Open finals on the line.
