Hritzuk has won two provincial championships as skip, once in 1985 and again in 1988. This qualified him for the Brier both times. At the 1985 Labatt Brier, he finished the round robin with a 6-5 record. He had to play in two tie-breakers, which he won to get to the semi-final, where he lost to Northern Ontario's Al Hackner. At the 1988 Labatt Brier, he finished the Brier with an 8-3 record, and lost to Alberta's Pat Ryan in the final. It would be his last Brier.
