Second set: Elina Svitolina 6-4 5-2* Katie Boulter: Svitolina captures her fourth and fifth consecutive games to move to within a game of victory. The fifth seed is so solid and refusing to give up any free points now, while Boulter is just beginning to be a little too erratic. Boulter closed off her service game with two consecutive backhand unforced errors, then Svitolina strolled to another easy hold.
