"She was hurt, she wasn't confident," he said. "I was afraid she couldn't take a good shot on goal."
As it turned out only two of the five Sissonville players were able to do that.
Meanwhile the Irish received shootout goals from Mullen, Brianne Ross and the game-winner from Sophia Bumgarner.
Each keeper, Annie Crockett for Catholic and Brooke Reed for Sissonville, made one save in the shootout.
"I can't believe we lost this game," Sadeghian said. "We had so many chances."
It marked the fourth time in the last five years the Irish have eliminated the Indians in a tight regional final.
The boys game had no such suspense.
Sam Revercomb gave Charleston Catholic a 1-0 lead going into the half. The Irish then put away the game with three goals in 13 minutes early in the second half.
Adam Fox started the onslaught at the 35:23 mark followed by Anthony Cipollone finding the net with 22:57 remaining and William Scriptunas finishing the scoring just 36 seconds later.
"They were packing the box on us in the first half," Catholic Coach Sam Fox said. "We made some adjustments at halftime and pushed the ball wide instead of down the center."
"Once we got the second goal they couldn't pack it in anymore."
Williamstown keeper Garrett Butler finished with eight saves, while Mitch Thorsteinson had two for the Irish.
