Tierney stopped the Crimson five times while allowing four strikes.
Junior goaltender Keith Cynar had another busy day for Harvard. Cynar made 19 saves on the afternoon.
"[Cynar] made some great saves out there for us," DeVries said.
Despite dropping its third straight game, Harvard, a team with just one senior, extracted many positives from the effort. Predictably, most centered around the first half and final quarter.
"We have a young team," DeVries said. "We learned that we have the skill to play with most of the teams in this league."
At this point of the season, the lessons Harvard draws from each game are critical. With just four games remaining this year, the Crimson are playing with an eye towards next year.
"We are improving in all areas of our game," DeVries said. "The younger guys look to us juniors for guidance in lifting their play."
Next up, the Crimson will host Yale this Saturday at home. The Elis are coming off a big win against Townson State and will look to extend Harvard's losing streak.
"Yale always comes at us strong," DeVries said. "We need to possess the ball. Our `D' has played great all year, but if we don't control faceoffs it's gonna be tough."
