(CNN) โ€” Venus Williams rolled back the years with a vintage performance to secure her first win against a top-20 player in four years.

The 43-year-old Williams defeated Russian Veronika Kudermetova 6-4 7-5 in the first round of the Western & Southern Open in Cincinnati on Monday.

Kudermetova is seeded 16th in the tournament and would have been expected to ease her way past Williams, but the seven-time grand slam winner had other ideas.

โ€œDefinitely satisfaction from today is (from) all the work that goes into just being here at all,โ€ the veteran American said after the win.

โ€œI did my best to be here as soon as possible in the best form possible I could bring in that amount of time. So that makes it satisfying, to be able to get a win with very little time to prepare.โ€

In both sets, Williams found herself 4-1 down and on the back foot, but, as on so many occasions throughout her career, she found a way to battle back.

โ€œI think at some point when youโ€™re down a double break, you start to think, โ€˜Well, I at least want to just hold serve for the rest of this set,โ€™โ€ Williams said. โ€œSimple thoughts like that. Then you get a little bit closer. Youโ€™re like, โ€˜Okay, maybe I just want to win another point.โ€™

โ€œDefinitely some big holes today that I usually donโ€™t play from โ€ฆ But thatโ€™s tennis. Thatโ€™s whatโ€™s so exciting.โ€

Williams will now wait to see who she faces in the next round in Cincinnati as she continues her preparation ahead of the 2023 US Open.

Her previous victory against a top-20 opponent also came at the Western & Southern Open in 2019 when she defeated Kiki Bertens in the second round.
