Dempsey, Mychal Johnson and Mychelle Johnson were all-tournament selections.
"They just play together so well,'' Lewis said. "When Asia can get the rebound and lead the break and all five can make the 3 and handle [the ball], it's tough to match up with them.''
The Irish feasted in the open court, turning 29 St. Marys turnovers into 4 points. The Blue Devils, who outrebounded St. Joe 36-32, could only muster 25.6 percent shooting, including 19.2 percent after halftime.
St. Marys pulled within three points (13-10) with 1:32 left in the opening quarter on senior forward Audra Clark's jump shot, but that would be as close as the Blue Devils would get.
St. Joe then buried St. Marys with a 20-0 run spanning the first two periods, and when it was over the Irish owned a commanding 33-10 advantage. St. Joe outscored St. Marys 43-10 from the end of the opening quarter to the end of the third period.
"I'm pretty sure they were triple-teaming me, but it was just one of those things [where the shots] wouldn't fall,'' said Clark, who earned all-tournament honors after finishing with 10 points and 11 rebounds. "I tried my best. Every girl tried her best. It just didn't happen.''
Clark and St. Marys 6-4 junior center Kendra Walker, who had six points and four boards Saturday, earned all-tournament honors.
