ITHACA and HAMILTON, ION, N.Y. Junior Scott Tusco scored with 1:11 remaining in overtime to give the undefeated Harvard men's hockey team a 6-3 come from-behind triumph over Colgate last night at Starr Rink.

The victory came on the heels of a performance by goalie Grant Blair that allowed the squad to escape from Cornell's Lynah Rink with a 5:5 overtime tie Saturday night.

The junior's 49 save before a relentlessly hostile crowd of 4100 set a new Harvard single-game record.

The Crimson, now 7-0-1 (5-0-1, FCAC) remains the only unbeaten, team in Division 1, in sole possession of first place in the ECAC.

At 19:05 of yesterday's third period, trailing 5-4, Harvard Coach Bill Cleary pulled net minder Grant Blair and replaced him with a sixth skater, Fusco then won a faceoff in the Colgate zone, and led the puck to Mark Banning at the right point.

Benning slid the puck to Brian Buscon tempotarily shifted to the blue line, and the senior let loose with a low, hard shot.

Peter Follows, the extra Crimson attracker, deflected the puck in past Red Raider goalie Jeff Cooper, giving the Crimson new life with most 55 seconds left in regulation.

With 1:19 to go in the ensuing up-and down overtime, Fusco's line took to the ice. The junior center won a right circle faceoff and the puck scooted to freshman wing Lane MacDonald in the corner.

MacDonald led Fusco right in from, and the Crimson's leading scorer banged it home for the Harvard victory.

"Lane went into the corner and threw it behind the back," Fusco said, "The only place I could go was between his [Cooper's] legs, and it dribbled in."

Fusco's beautiful move spoiled a remarkable night for Cooper in the Colgate net. The goalie recorded 40 saves and kept his team in the game on several occasions.

Despite Cooper's best efforts, however, Harvard's first line continued its remarkable success.

Fusco had two goals and two assists on the evening, extending his multiple point game streak to seven. The junior now has 11 goals and 11 assists on the year for 22 points, four more than last season's leading scorer's total for the year.

Tim Smith upped his goal scoring streak to eight straight games (the Harvard record, held by Coach Cleary, is 15). With a score and three assists on the night. Smith now has nine goals and six assists MacDonald picked up two goals and two assists on the evening.

The freshman played against his brother Lowell, a Colgate sophomore, who noticed, a goal between his brother's two first period rallies.
