Princeton tied the game with a power play tally, when Aaron Ave struck in the first.
But it was the only special teams victory for the Tigers (1-4-1, 1-3-0 ECAC), who fell to the Dutchmen (6-5-1, 1-4-1 ECAC) 6-1 on Saturday night.
Princeton allowed Union to convert three of five power play chances, which helped Dutchman Daniel Ciampini to his first hat trick since the 2014 Frozen Four.
“Union won the special teams,” Princeton coach Ron Fogarty said. “They were 3-for-5 on the power play and had two quick goals in the second in a four-minute span to put the game a little bit out of reach.”
The Tigers were out shot 37-16 on the night, and have yet to out shoot an opponent. The loss marked the second time this season Princeton has allowed six goals.
Ben Foster assisted on Ave’s goal, and the pair now lead Princeton in scoring.
Ben Halford earned his first collegiate start at Messa Rink, not too far from where the Albany Academy graduate grew up.
“You have to give him a chance, you can’t run with one goalie for the whole year,” Fogarty said.
Halford finished with 31 saves, a career high for the freshman. The game marked his first appearance since Princeton fell to Merrimack at the Liberty Hockey Invitational on Nov. 2.
“I thought he played well,” Fogarty said. “He tracked pucks well [and] he saw a lot of quality chances on the power play. They were peppering him [each time] on their power play. … I’m proud of him.”
With Tom Kroshus injured, Hayden Anderson made his season debut in place of Marlon Sabo.
“He deserves to play,” Fogarty said. “He had a great week of practice.”
Kyle Rankin was also still out of the lineup, and Max Becker played in his second straight game. It was the first time this season the freshman played in back-to-back games.
“Max Becker played well,” Fogarty said. “He was buzzing, he was creating plays on the forecheck and he had a very solid game.”
