After a hard-fought four-hour quarterfinal that went down to the wire, defending champion Advani had to return to the table for the crucial semifinal without much of a break.
His opponent Andrew kept the pressure and reached the final after notching up a 14-74, 8-71, 0-87, 78-64, 0-81, 70-37, 7-80, 37-68, 19-74 win.
Advani now heads back to Bangalore to switch to the 3-ball game in preparation for the World Billiards Championship that commences from December 5.
The Indian is the only player in the world to compete at the world championship level in both sports and be successful in all the formats of both billiards and snooker.
Result: Andrew Pagett (Wales) beat Pankaj Advani (India) 7-2: 14-74, 8-71, 0-87, 78-64, 0-81, 70-37, 7-80, 37-68, 19-74.
