When Parrott won the first four frames the question was not whether he would prevail but if a rare whitewash was on the cards. However, Wattana, who had practised intensively during the fortnight since his opening match defeat in the Regal Welsh Open, re-emerged from the mid-session interval with renewed vigour. He fired in a 133 clearance to break his duck, won a scrappier sixth frame and put together contributions of 100 and 113 to draw level.
Wattana squandered an opportunity to move 5-4 ahead when he overcut a black off its spot at a crucial moment in frame nine and a relieved Parrott was able to gain the advantage, thanks to a 34 clearance.
Despite the setback, Wattana then confidently posted runs of 60 and 71 in the closing two frames to score an unlikely success.
