No. 6 Dartmouth swaggered into Bright Hockey Center coming off a 4-3 stunning upset over No. 3 UNH and confident it could turn the trick again.

It nearly did.

Instead, the No. 1 Harvard women's hockey team prevailed in overtime, 4-3, and then defeated Boston College yesterday, 10-0, to push the nation's longest winning streak to 23 games. DARTMOUTH  3 HARARD  4 BOSTON COLLEGE  0 HARVARD  10

Sophomore winger Tammy Shewchuk sent the Bright crowd of 1,023 fans home happy Saturday with the game-winning goal 2:52 into the extra period.

Co-captain A.J. Mleczko drew the puck right to her of the face-off and Shewchuk sent the puck between the legs of Dartmouth sophomore goaltender Meaghan Cahill, who had mad 26 saves before that shot.

"I like to walk the seam ands that's exactly what I did when the puck popped back after the face-off," Shewchuk said. "We needed shots so I took one hoping that we would at least get the rebound. Fortunately, it went through her five-hole and we scored."

That came 58 seconds after Cahill kept the Big Green (14-7-5, 13-6-5 ECAC) alive by making a Hasek-esque glove save out of the butterfly on a similar shot from Shewchuk in the slot. But Harvard (26-1-0, 22-1-1) continued to pressure the Dart-

mouth netminder, out-shooting the Big Green 6-1in overtime.

"Their goalie's glove was working well,"Shewchuk said. "But we had noticed that she wasn'tas quick with her feet as she was with her gloveso we tried to capitalize on that."

The Big Green forced overtime by converting atwo-on-one breakaway with 11:06 left in regulationwhen sophomore forward Carrie Sekela banged home ashot from the left post on Dartmouth's bestopportunity of the game.

After that goal, however, it was all Harvard asthe top forward line of Mleczko, Shewchuk andfreshman Jen Botterill finally began to churn outtheir usual multitude of scoring chances.

However, Cahill and the physical Big Greendefense in front of her held their own untilShewchuk's shot.

"It took us a while to score that fourth goalbut we dominated the overtime," Mleczko said."Dartmouth's third goal deflated us for a momentbut we were able to round up and get some greatchances. Their goalie saved them in overtime untilTammy came through for us."

Perhaps the biggest scare for the Crimson camewith 7:33 left in regulation when a Dunn hookingpenalty gave the Big Green its sixth and finalpower play.

Although Dartmouth controlled the puck with theman advantage, it sent few quality shots towardsfreshman goal-tender Alison Kuusisto, who turnedthem all aside.

Tempers flared at the end of what was a veryphysical hockey game when Dartmouth sophomoreforward Jennifer Wiehn deflected a slapshot byHarvard freshman defenseman Angela Ruggiero. Wiehnstretched for the puck and Ruggiero pushed heronto the ice before exchanging shoves withDartmouth senior forward Kathleen O'Keefe.
