This was the first time that the Championship had been held in Houston at a fantastic new snooker facility in the city, and it was an incredible event for the 35-year-old from Florida as he was fortunate to qualify from the group phase after suffering two defeats out of four matches, but he slowly forged his way into the Championship and gathered momentum with each match played to reach the final against the defending champion, Sargon Isaac.
Number one seed Isaac made a very underwhelming start to the final as he found it difficult to take advantage of any chances, and Deuel's commanding presence helped him win the first two frames comfortably.
Isaac hit a very fluent and precise run of 68 to win the third frame and it appeared the tide was turning, but Deuel found his range with a break of 53 to lead 3-1 into the mid-session interval.
Deuel completely dominated proceedings from then on as a break of 36 helped him seal frame five, and runs of 34 and 39 in the following frame helped him wrap up the match 5-1 for a terrific victory.
Both players have now gained automatic selection to represent the United States at the IBSF World Championship, which will take place in Riga, the capital of Latvia, from November 18-30.
