20th seeded Victoria Azarenka has made it to the last-8 at the US Open, dumping American Varvara Lepchenko in straight-sets, 6-3, 6-4.
"Just being solid, being aggressive, dictating the play. Her ball is a little bit uNPRedictable. You know, sometimes it comes fast and heavy; sometimes it comes high and slow. So it's a little bit more difficult to time. But just really being solid and stepping up and trying to control."
Azarenka, a former world number-1, is due to battle Romanian number-2 Simona Halep.
She narrowly got past Germany's Sabine Lisicki in a third-set tie-breaker.
