Serena Williams will continue her run at the 2018 U.S. Open in the quarterfinals on Tuesday night against Karolina Pliskova.
Williams, the No. 17 seed, defeated Kaia Kanepi 6–0, 4–6, 6–3 on Sunday to advance. Before facing Kanepi, Williams faced her sister, Venus, for the 30th time in their professional careers.
The 36-year-old Williams is looking for her 24th Slam singles title and seventh U.S. Open victory. It would be her first major since she won the 2017 Australian Open while pregnant with her daughter Olympia.
Pliskova, the No. 8 seed, defeated Ashleigh Barty to move on.
