Freshman Hannah Humphreys had a season-high 28 saves in Dartmouth's narrow 1-0 loss to Yale at Thompson Arena on Friday evening.
Fellow rookie Catherine Trevors tried to get on the scoresheet for the third game in a row with her five shots but was denied.
Dartmouth (0-3-0, 0-2-0 ECAC Hockey) and Yale (3-0-0, 1-0-0 ECAC Hockey) played aggressively from start to finish, committing a combined 13 penalties.
"There were lots of good things about tonight," head coach Laura Schuler said after the game. "I think we are starting to play really well in the D-zone. And Hannah was outstanding for us. Now we need to hone in on our power play and get that producing for us."
The teams played a very even first, with the Bulldogs leading in shots, 10-6. There were a number of close calls, but the game remained scoreless.
Kaitlyn Rippon scored the Bulldogs' lone goal at 4:19 of the second, sending the puck just past Humphreys' right skate. The Green fought to even the score, and got close a few times, but headed to the third period trailing by one.
The game continued at a fast pace in the third. It looked as if sophomore Gabby Billing had scored the equalizer just 28 seconds into the third, but the goal was called off due to goalie interference. Dartmouth kept fighting until the final whistle, pulling Humphreys with 26 seconds to go for the extra skater, but the Bulldogs' Tera Hofmann held on to the shutout.
Yale led in shots, 29-20.
Dartmouth will be back on Saturday to host Brown at 3 p.m.
