Cornell prevented Harvard from gaining its first Ivy League victory of the spring by rallying to edge the Crimson, in lacrosse, 7-5 on Saturday.

The Big Red caught the Harvard defense napping in the third period and erupted for five goals within a space of four and a half minutes. Harvard at the time held a 3-1 lead and enjoyed a two-man advantage over Cornell.

Earlier Keith Hutchinson and Marty Cain swept the Crimson out to a 2-0 lead in the first period. They both picked up loose balls in first of the Cornell net and pushed them by the down-and-out goalie.

Cornell got a goal back late in the first period, while Harvard had a man in the penalty box. The 2-1 score stood up till the half.

Harvard fans sensed an upset when senior Ted Leary popped up the first of his three goals at the beginning of the third period.

Then the deluge came. A Cornell attackman started the wild flurry by picking up a pass from his defenseman and slipping by Harvard's midfielders. He broke in on the surprised Crimson defensemen and fired the ball right past goalie Ron Wilson before the defense could stop him.

The goal came when Cornell was two men down and brought the Big Red to life. Meanwhile the Crimson defense collapsed just as it did earlier in the season against Washington.

Harvard fought hard but two penalties in the last three minutes ruined the Crimson's chances for a tie.
