Radcliffe's basketball team stretched its undefeated skein to three games by walloping Pine Manor, 37 to 20, yesterday in the Annex gymnasium.

Ann Brace and Captain Ann Luyten paced the Annex sextet with 12 and 10 points respectively as the home team led from the opening whistle.. While the crimson-clad winners scored five baskets in the opening period, they held their yellow-tunicked antagonists to one and led 10 to 2 at the quarter..

The feminine cagers, playing with six on a team, used a "shifting-line-zone-defense formation" and played eight minute quarters. At the half, Radcliffe's six led the junior college cagers by a 21-9 margin.

Playing alert defensive ball, 'Cliffe guards Ellen Deitsch, Anne Gordon, and Margaret Smertenko held Pine Manor forwards scoreless in the third quarter. The yellow-clad lassies rallied to score 11 points in the final period against Radcliffe's seven, but failed to catch up to the hot, early-game pace set by the home team.

Radcliffe's high-flying hoopsters will attempt to extend their winning streak Saturday in the annual inter-collegiate play-day at Wheaton. The undefeated basketballers will face Wheaton, Simmons, and Bouve in half-length games.
