The game would have looked a lot different had Egan scored early in the second half, as a goal would have given the Eagles confidence in addition to momentum.
"We were creating, I don't know what it was," Egan coach Andy Adamiec said. "We weren't actually shooting real shots.
"I think the second goal took the air out of us a little bit."
Central Catholic junior Frannie Crouse was the difference in the first half, getting the lone goal of the first 40 minutes and registering five shots on net.
The Penn State recruit, a forward, opened the scoring with seven minutes remaining in the half, turning from 25 yards and letting a shot rip high into the right corner of the net.
Crouse was dangerous all game, leading the Centurions attack and eventually scoring another goal and assisting on another.
"We thought at halftime that we would come out stronger," said Conwell-Egan's Grace MacNamara, a junior midfielder. "We knew we needed to come out and score the next goal."
After the Eagles' second-half chances, the Centurions scored two goals in nine minutes. With Conwell-Egan down 3-0, the game became out of reach.
The Centurions (22-1) won their first two state tournament games by a combined 13-2, before advancing to the final on penalty kicks. The District 7 winner, Central Catholic had lost the state final in 2005 and 2006.
MacNamara scored the lone goal for the Eagles, whose appearance in the Class A title game was their first.
