Yousif and Yannaphon appeared to find the conditions difficult and were unable to make any impact. A big split in the fifth frame by Yannaphon put the Thai to trail Yousif even further.
Both found a strike each in the eight providing Yannaphon a slight hope if he could strike out. Yousif made a good pocket shot only to see pin 7 and 10 standing firmly. The spectators were delighted to Yousif sparing the almost impossible 7-10 split. But Yannaphon was unable to strike out and encountering a split in the last frame to end with a low 155 to Yousif's 187.
"The lanes were very much different from the semi-final match we had earlier," said the 31-year-old ex-Bahraini national bowler, who made the TOC after bagging the 2014 Dubai leg.
"Both of us struggled but I was more fortunate than Yannaphon. Sparing the 7-10 split was the saver because if I had failed to spare it, Yannaphon could still take the match by striking home.
"I have been to two TOC but have never progress beyond the second round, so this win is especially sweet for me after I failed to make the finals of the KUwait Open two days ago."
Yannaphon reached the finals by eadging remaining Kuwaiti, Khaled Al Dubyyan, 223-213 in the other men's semi-final match to face Yousif. The champion had earlier ousted third-seed, Hussain Al Suwaidi of UAE, 234-210 in the quarter-finals to reach the semi-finals.
