In the men's section, former National champion Rupesh Shah outwitted 13-year old Japanese Keishin Kamihashi 4-0 for his fourth win in Group J to advance to the round of 64.
The match was closer than the scoreline might suggest as the Japanese schoolboy from Nagoya had Shah in trouble in a couple of frames where the Indian had to fight from behind.
Shabaaz lost to Bolton 2-4, but still booked his slot in the knockout stage on the back of his three wins in Group F which Kamal Chawla topped with five victories and one loss that he suffered today against Singapore's Ang Boon Shin who came through in seven frames.
Brazilian Denise Santos set a new benchmark for women with a splendid break of 91 while defeating Irina Gorbataya of Russia 3-0 in a Group E encounter.
While the victory, only her second in five outings, did not assure 18-year old Santos a place in the knockout phase, it kept her in the hunt, but more importantly, she showcased her potting and break-building prowess.
