Unlike their last two opponents, Westfield is not ranked in the state polls.
But Aguillon said the girls remember the regular season meeting with the Shamrocks that went down to the wire.
"I think it helps that we only beat them 1-0 and it was really a last-minute goal," Aguillon said. "The girls know it is going to be tough. We are beat up physically. We have to make sure in the next 48 hours the girls get some rest and get ready for the game."
Aguillon said it also helps that they had to get over an emotional win Tuesday to regroup for Guerin.
Now after another big win, he doesn't expect the regrouping to be too difficult.
"That Carmel win, it felt like it was the state championship game and then tonight it was the same caliber," Aguillon said. "I don't know if you can get a better atmosphere than we had tonight. It was like another state championship game and our girls rose to the challenge. Now we can celebrate tonight, but we have to get ready for a very good Westfield team on Saturday.
Kick-off is scheduled for 6 p.m. at Carmel on Saturday.
