While both performances were nearly identical, Mammola was instrumental in the opening win by recording five breakaway saves -- four of which came in the second period.
"The score was 4-2 in the second, and any one of those breakaways gets [St. Clair] right back in the game," Battista said.
The Icers' offense wasn't especially dominant -- at least in shots -- but made the most of its scoring opportunities.
All four lines contributed with a goal over the weekend, and Penn State went 5-for-12 on power play opportunities.
After outshooting last weekend's competition roughly 3-to-1, Penn State managed to garner a total of only eight more shots than a tough St. Clair squad.
Still, that statistic isn't all that bad when one considers that St. Clair won the Canadian Ontario College Championship three out of the last four years.
"We knew they would be a quality opponent," Battista said. "The score just wasn't indicative of how tough these games were."
It almost appeared as though both matchups would be a shootout, too. In the pair of games, a total of six goals were scored in the opening six minutes of each game.
Of course, the Icers seized the 2-1 advantage on both occasions and never trailed.
Battista pointed to Mike Carrano's play as one of the deciding factors over the weekend.
Carrano finished with five goals and one assist -- including an incredible one-handed effort, in which he used one arm to ward off defenders and used the other to flip the puck into the left corner of the net.
"He's scoring goals in different ways," Battista said. "One was a tip, a couple were deflections, and a couple were shots."
Offensive dynamo Kevin Jaeger also played a huge role in the Icers' success, as he recorded two goals and six assists.
While the two red line players contributed a lot on the offensive side of the ice, Battista said there were two other differences in the game.
"Our goalkeepers outplayed theirs," he said.
"And the other one was that we stayed out of the penalty box moreso than they did."
