Hill opened the scoring just 1:25 into the contest, but Buffalo State answered just 24 second later on a tally by Jason Hill (Niagara Falls, NY). Plattsburgh took control from there, however, connecting on 5 of 10 power play attempts.
Phil Farrow extended the Cardinals lead to 3-1 in the second period. CJ Tozzo, Dylan Clarke and Mike Thomson added third period goals for the Cardinals to seal the win.
Plattsburgh outshot the Bengals, 38-14.
Buffalo State will host Potsdam tomorrow at 7 p.m.
