The youth movement was working early in the game, as Penn State freshman forward Jason Yeisley scored twice within the first 15 minutes.
However, Towson went on to score three unanswered goals late in the contest.
The Tigers' first goal came in the 76th minute, with the tying goal coming minutes later. At the 101:34 mark in overtime, Towson's Cesar Cisneros put in his second goal of the afternoon and secured the victory for Towson.
With underclassmen minding the backfield and clearing balls up the middle, inexperience goes a long way in explaining how Towson, who was 3-5-1 competing in the Colonial Athletic Association last year, stormed back to take the victory.
Fortunately for the Lions, the game can be measured as a learning experience.
It can be as though they hit a bad slice, but no one was around to see it.
"We'll get there," Gorman said. "It's better to have that happen in an exhibition than when it really counts."
Penn State's Milan Popovic (7) heads the ball just wide of the net.
