Yale's upset of Penn's soccer team last Saturday has put Harvard in position to clinch its first Ivy title since 1963 if it can tie defending champion Brown Saturday in Providence.

The Elis had been in seventh place in the league without a victory over an Ivy opponent. while Penn had lost only to Harvard and was ranked tenth nationally. Yale coach Hubert Vogelsinger used a man-to-man defense and a breakaway offense in an effort to halt the Quakers and his team played its best game of the season to down Penn, 2-1.

Ohene Frempong scored both of Yale's goals, and Penn's only tally came on a shot by Rob Walkins while goalie Steve Greenberg, thinking the first period had ended watched.

Harvard did not have an easy time either and narrowly missed being upset by Princeton, the eighth team in the league. But a goal each by Solomon Gomez. Pete Bogovich, and Charlie Thomas enabled the Crimson to remain undefeated with a 3-2 win.

Penn's only hopes for the title depend on victories in games against Columbia and Dartmouth and two losses by Harvard. Even if that should happen. Penn could only gain a tie for the championship.

Brown has a slightly better chance of winning. The Bruins must beat Harvard and Columbia while the Crimson must lose at Yale. In that event, Brown. now 3-1-1 would win the title outright.

The Bruins moved into second place with a 2-1 triumph over Cornell. They let the Big Red, 2-0 going into the final quarter, and then Nick Alexandridis scored on a penalty kick to cut down the lead. but Brown held off Cornell the rest of the way. In the fourth league game. Columbia moved into a fourth-place tie with Cornell by downing Dartmouth, 4-2.

Gomez is still first in the Ivy scoring race. He now has ten points, four more than Bogovich and three others, all of whom are tied for second, Harvard's Phil Kydes has five points.

The Crimson must also think about the NCAA playoffs, which start Monday in Cambridge. Two victories in the New England single-elimination tournament and a win over the New York area champion are necessary if Harvard is to make the trip to the nationals in San Jose.
