Amanda Anisimova secured a comeback win over top-seeded Aryna Sabalenka at the Charleston Open on Thursday, 3-6, 6-4, 6-3.

The American lost her serve twice in the first set but managed to pull back one break before losing the set.

From there, Sabalenka continued to have trouble with her serve, hitting just 48 percent of her first serves. Sabalenka has struggled with her serve since the beginning of the season, including serving up 12 double-faults during the second round of the Australian Open.

She managed a tight win against Alison Riske during her opening match in Charleston, saying after that she was “super happy” to make it through the match. But the Belarusian could not hold off Anisimova in the round of 16.

For Anisimova, the match marks her third consecutive win against the world No. 5. It also clinched her second trip to the quarterfinals this season.
