British number two Heather Watson had to battle through three sets to beat China's Kai-Lin Zhang in the first round of the Hong Kong Open.
Watson dropped her serve three times as Zhang took the opening set 6-3 despite not serving her first ace until the third game of the second set - in which Watson nevertheless broke to take the lead.
It was part of a sequence of seven straight games for the Guernsey native, who broke twice more in taking the set 6-1 and saved three break points in the first game of the third set.
She broke again in the fourth game of the decider and saved several more break points in the next, which she eventually won with three straight aces to take a 4-1 lead.
Zhang eventually got another game on the board but a final break earned Watson a 3-6 6-1 6-2 win in two hours and seven minutes.
