In what was his first appearance in the Championship, Isaac proved to be a revelation as he performed very well in winning all of his group matches in addition to his last-16 and quarter-final ties without dropping a frame - it was not until the fourth frame of his semi-final against Jack Kung did he finally lose a frame.
26-year-old Isaac faced his regular practise partner at Shoreline Billiards in Mountain View, California, Ajeya Prabhakar in the final, in what would be a repeat of the final event of the 2011-12 United States Snooker Association (USSA) Tour played last month at Shoreline Billiards.
For the highly experienced Prabhakar, playing in his fifth championship final and the third in the past four years, it was an opportunity to finally get that second title he so desired after he had earlier put out the defending champion Ahmed Aly in an epic semi-final encounter.
Isaac, who grew up and learnt his snooker in Nottingham, England, has lived in the United States for six years and is now an American citizen. He took initial control of the final which was being streamed live to a worldwide audience over the internet.
He went into a 2-0 lead after winning the first two frames but a run of 32 by Prabhakar helped him to decisively seal the third frame, and he then pinched frame four on the final black ball to level the match at 2-2 going into the mid-session interval.
On the resumption of play, Prabhakar never really got back into the match as he lost frame five and appeared fatigued after his earlier long semi-final battle.
Isaac then proceeded to win the following two frames, conceding only thirteen points to Prabhakar in the process, to wrap up the match in a convincing 5-2 victory and take his first Championship title at his first attempt.
Both Isaac and Prabhakar have now gained automatic selection to represent the United States at this year's IBSF World Snooker Championship in Sharm El Sheik, Egypt, from November 4-16.
