Hareb Al Mansoori started off the finals with a double as his more experienced compatriot failed to match his pace but picking up all his spares. The 36-year-old stepped up with four strikes-in-a-row from frame six to open up a gap of 30 pins.
Although Sayed responded with a double in frames eight and nine, it was a bit too late for the 38-year-old Sayed going down 205-244. Hareb, who has been bowling for nine years and have made numerous appearances in the tour, finally nailed his first tour title.
Hareb, who had earlier routed top seed, Wu Siu Hong of Hong Kong, 211-148 in the first semi-final to advance to the finals while first runner-up, Sayed edged Thailand's Yannaphon Larpapharat, 245-224 in the other semi to face Hareb in the finals.
