Baek, who topped the earlier 6-games preliminaries to qualify for the quarter-finals, trashed eighth-seed, Alisha Nabila Larasati of Indonesia, 258-157 to advance to the semi-finals. The Korean was nearly eliminated in the semi-final match against seventh-seed, Zhang Yuhong of China but got a lucky break when Zhang suffered a split in her final frame to hand the match to Baek, 204-213.
In the title match against fourth-seed and 29th SEA Games Doubles gold medallist, Tannya Roumimper of Indonesia, the 26-year-old Baek spared her first frame before knocking down two consecutive strikes in the second and third frames to open up a gap of 11 pins.
Roumimper struck in her opening frame and spared her next two frames. Both had two additional spares in the fourth and fifth frames but the Korean struck twice again to extend her lead to 39 pins when her opponent missed a single pin spare in the sixth frame and failed to convert a three-pin spare in the seventh frame.
