Prep outshot Hamden 14-11 in the second period but was Hamden who came away with a one-goal lead.
With goalie Spencer Sodokoff being pressured on the right side, forward Pat Lynch wristed a shot near the post to give Hamden a 3-2 lead at 2:33. Prep forward Darric White responded with a power-play goal at 5:02 to tie the game at 3.
Hamden went on to take a 4-3 lead at the second intermission thanks to a 5-on-3 man advantage - Prep’s Matt Brophy serving a slashing penalty and teammate Lucas Dennison serving an unsportsmanlike penalty.
Adam Devine’s shot from the left wing rebounded off Sodokoff to C.J. Carignan whose rising shot went into the upper right corner to make it 4-3 Hamden at 9:06.
