Mark Beebe and the B.A.A. Unicorns prodded the Varsity puckmen 7 to 6 last night in a bitterly contested overtime match at the Boston Arena. The score at the end of the regulation three periods stood at a 5-5 tie.

Beebe, one of the many pre-war Crimson hockey greats to dominate the B.A.A. squad, was high scorer with two goals and two assists. He notched the gameclinching seventh marker halfway into the overtime frame on a solo spurt from mid-ice, after drawing Jack Lavalle out of the Crimson nets.

The Unicorns, with a previous 6-1 win over the Chasemen, showed greater ease and speed in skating, and profited from their longer experience on the ice. Superior teamwork kept the Crimson even until halfway into the final period, when they tired and allowed the opposition two quick scores and victory.

Sears, Varsity High-Scorer

Wally Sears, present high man on the Varsity scoring ladder after two more tallies last night, brought the battle right down to the final whistle with an unassisted goal in the final minute of play, and the contest ended with the puck in the vicinity of the B.A.A. cage.

Tom Moseley's third line, with Bill Ayres and George Gebelein at wings, had an active and effective evening which saw Ayres score twice. Freshman mentor Stan Priddy teamed with Greeley Summers to form a rugged Unicorn defense. With Goodie Harding making his usual incredible stops, the B.A.A. goal was undented for 27 minutes.
