Aryna Sabalenka kicks off title bid with Stefanos Tsitsipas and Dan Evans to come

BREAK! – SABALENKA 5-3 KOSTYUK

Kostyuk appears to be on control of the game at 30-15 but hammers a routine smash just wide of the tramlines.

Sabalenka sees the opportunity and cranks up the heat at deuce. The Belarusian unleashes the power to earn yet another break point and then sweeps a winner that paints the line to make it three games in a row.

She will now serve for the set.
