Next Saturday's traditional league finale against Yale, usually a game which decides nothing but prestige, has assumed decisive importance, as the Crimson and Eli baseball teams each enter the stretch of the pennant race undefeated.

Harvard continued its drive for the title Saturday by easily overpowering a hapless Cornell club, 7 to 1, for its seventh straight victory. This kept the varsity abreast of the rampaging nine from New Haven, which blanked Princeton, 3 to 0.

Each team has one more league game to play before Saturday, but regardless of the outcome of these contests, the head-on encounter between the two will decide the championship, as no other club has lost less than three games.

Before Yale, the varsity must meet a hot-and-cold Brown team which can give plenty of trouble, as demonstrated by its close 1-0 loss to Yale. Yale's remaining game is with Dartmouth, which the varsity defeated, 3 to 0.

Ken Rossano, the number two Crimson pitcher, was the whole show against the last place Big Red. Besides hurling a seven-hitter, and never really being in trouble, he was also the batting star, with two doubles and a single.

After the visitors tallied their lone run in the first inning, on a single, two stolen bases, and a missed throw, Rossano effectively kept them in check the rest of the way, registering his sixth victory out of the team's total of 15 wins in 17 games.

The Crimson attack again took advantage of its opportunities, with nine of its 11 hits figuring in the scoring. All the runs came in two big bursts, one good for four tallies, the other for three.

Held to one hit in three innings, the varsity exploded in the fourth for its best inning of the year. Ten men went to the plate, five got base hits, two reached base on walks, and four scored.

A base on balls to Bill Cleary began the uprising. After Cornell hurler Bill DeGraff wild-pitched him to second, Matt Botsford started the hit barrage with a smash to right, driving in Cleary. Bill Chauncey singled home Botsford, who had reached second on the throw to the plate.

Chauncey stole second, and scored on George MacDonald's bullet to center. Rossano doubled him to third, and Dick Hoffman walked to load the bases. Then John Simourian came through with a drive to right to score MacDonald, keeping the bases filled. Bill Cleary, up for the second time, hit a hard grounder to third, to force Hoffman and end the inning.

The only other scoring came in the eighth, when three unearned runs tallied. After Botsford reached base on an error, he scored as Jim Rahal, substituting for a sick Don Butters at third, singled to left. Two more runs crossed the plate on MacDonald's double, and back to back singles by Hoffman and Simourian.

In freshman action Saturday the B team beat Middlesex, 6 to 1, and the regulars massacred Northeastern, 23 to 2
