Princeton returns to the ECAC Championship weekend for the first time since 2009 with a sweep over ranked Union. Eric Robinson’s short-handed goal, good for his 15th of the season, gave the Tigers in their two-goal lead in first period, but Union rallied to tie it, only to see David Hallisey score with 10 seconds left in the game to lift Princeton to the sweep. Jake Kupsky made 19 saves on the night for the Dutchmen.
