Dunn, currently ranked number 38 in the world, started brightly winning the opening frame and the Cleveland Cueman took advantage of his opponents sloppy mistakes by doubling his lead taking the second.
Former UK Championship winner Ding Junhui struggled to find a foothold in the opening stages but looked to have settled down in the third, pulling a frame back with a break of 71, but Dunn’s reply was instant as the Englishman stretched ahead once more taking a 3-1 into the mid-session interval.
Ding, with a little help from two fouls from Dunn, compiled breaks of 42, 24 and 35 to eventually secure the fifth frame after the mid-session interval, but once again his opponent hadn’t read the script and crept ahead once more taking a 4-2 lead.
Ding had the opening chance in a scrappy seventh frame but didn’t take advantage allowing Dunn to firstly make a break of 30 and two accidental in-off’s from Ding followed by a frame winning break of 24 gave Dunn a three frame advantage.
World number 13 Ding Junhui recorded the highest break of the match so far in the final frame of the afternoon session knocking in an impressive 114, but the 22 year-old from Shanghai still remains two frames behind at 5-3 going into this evenings concluding session.
