Portugal Colonial - Sabalenka surges past Townsend to reach US Open quarter-finals

Sabalenka needed all of her resolve against the multi-faceted Townsend.

The match opened with five breaks of serve before Sabalenka managed a comfortable hold for a 4-2 first-set lead.

Townsend's blistering service returns and the net prowess of the world's second-ranked doubles player flummoxed the Belarusian star.

She double-faulted to hand Townsend a break in the second game and Townsend broke again in the fourth with a massive service return.

But Sabalenka's sustained power and precision proved a little too much.

Townsend broke her as she served for the set at 5-2, but by the time the American managed a hold for 5-4 it was too late, and Sabalenka held serve for just the second time to pocket the set, saving a break point before putting it away with a trademark forehand winner.

The second set unfolded in more traditional style, neither player facing a break point through the first three games.

It was Sabalenka who blinked first.

Looking rattled after smacking a forehand into the net to give Townsend a break point, Sabalenka offered up a weak second serve that Townsend punished with a return winner for a break and a 3-1 lead.

Sabalenka immediately broke back, however, launching a run of five straight games to take the match.

The Belarusian, who must win to have a chance of retaining her number one status in New York, will face either sixth-seeded Wimbledon champion Linda Noskova of Czech Republic or 11th-seeded Ukrainian Marta Kostyuk for a place in the semi-finals.
