It's the Egyptian keeper's first perfect display as he conceded four goals in his past three games since playing for Sion in mid-April.
Dominguez hit a brace, 22 and 82, and goals from Mobulu, 35, Saborio, 50 and Grosicki 60, sealed the massive victory.
The result leaves Sion seventh of the table with 43 points.
