Raducanu has broken Zhang in the opening game of the second set. Zhang saved a first break point at 30-40 with a backhand winner at 30-40, then a second with a 98mph service winner for deuce, but finally blinked on the third with an unforced error off the backhand side. Raducanu then consolidated after falling behind 15-30 on her serve, capping the hold with a 97mph ace out wide. Fantastic stuff from Britain’s emerging star, who is closing in on a spot in the third round.
