The Icers answered back as a Joe Maglaque pass sent Justin DePretis in on a breakaway of his own to tie the game at one.
After giving up a rebound goal to Illinois' Mike Roesch, the Icers found themselves down by one goal with a period left.
However, if Penn State wanted to win the game, they had to figure out a way to beat last year's ACHA player of the year in Illini goalie Tim Danlow.
A quick pass from Mike Carrano to Kevin Jaeger gave Penn State the chance they needed as Jaeger went in on a two-on-two with Glenn Zuck. Jaeger slipped a pass through to Zuck who beat Danlow to the stick side and evened the score at two, setting the stage for McKeen's game winner.
The Icers were again beneficiaries of a strong goaltending performance from Blackman. He said he was a wall in net and only got stronger as the game went on.
The last thing Penn State needed was another injury to a defenseman. They started the weekend without the services of defensemen Chris Rome and Eric Harbaugh only to see captain and Curtiss Patrick go down in the first period of Saturday's game, with what could be a serious shoulder injury.
The remaining defensemen had to step up and fill the void left by these injuries.
"We're conditioned for this kind of thing." Maglaque said. "I just tried to play my game and step up to make some big plays I know Curtiss would have made."
Winning the Big Ten Tournament stretched the Icers' winning streak to 18 games and showed the league just how good the Icers are capable of being.
"It was a real big win," Maglaque said. "Overcoming the No. 2 ranked team showed we deserve to be No. 1. It showed if we work as a team we can overcome any team in the ACHA."
