1997-1998 Season Still be the world no.12 for another year as the result of reaching just the semifinal round of 1997 Embassy World.
Wattana's performance in this season was totally poor and not impressive when the deeptest round he reached was just the third rounds
In Thailand Open, I think many Thais still remember when James lost 4-5 after leading Ken Doherty 4-0. As his fan, I was totally dissappointed by the result...
And, again in the 1998 World Championship, Wattana would have gone to the second round, but as a matter of fact, he didn't, defeated 9-10 by Fergal O'Brien.
