The visitors carried their momentum into the third quarter, scoring the first two goals to open up a 6-4 advantage, their first lead of the afternoon. The Irish responded as Wynne cut Detroit's lead in half with his second score of the game to make the score 6-5 in favor of the Titans heading to the fourth.
