Harvard defeated Yale 10-2 on Nov. 26 in Bright Hockey Center, but this time the Crimson had to play through cooling problems at Ingalls Rink, which caused the Yale men's hockey team game to be transferred to the New Haven Coliseum, and managed only a 4-2 win.
The star of the game was Shewchuk, who recorded a hat trick and assisted on the Crimson's other goal, scored by Botterill.
Shewchuk was the only scorer of the first period, giving Harvard a 1-0 lead off assists from Botterill and senior defenseman Jamie Notman only 44 seconds into the game.
Harvard took the 2-0 lead when Botterill tallied halfway through the second, but the Bulldogs answered with a score from sophomore forward Deanna McDevitt five minutes later.
In the third period, Shewcuk netted the game-winning goal on the power play, off passes from senior forward Tara Dunn and sophomore winger Kalen Ingram, at the 18:06 mark, and scored once again seven minutes later to complete the hat trick and give the Crimson the 4-1 lead.
Sophomore goaltender Alison Kuusisto recorded the win for the Crimson, making 15 saves in the process.
Harvard's next game is Tuesday against Northeastern in the championship game of the Beanpot.
