In the Asian Under-21 Snooker championships, being played simultaneously, Lucky Vatnani really failed to qualify for the quarter-finals.

The youngster from Andhra Pradesh, appearing in his first international event, played great snooker to defeat John Loong of Malaysia 4-0 in his last league encounter.

But the victory did not help him qualify as the loss against a relatively easy opponent from South Korea earlier shut doors on his aspirations to make the knockout stage.
