Three M.I.T. golfers turned in top performances against the Harvard team yesterday, but Harvard won four matches to take its ninth victory of the season, 4-3.

The four winners--Yank Heisler, Tommy Wynne, Jack Purdy, and Joe Tibbetts--all dumped their men by large margins. Two of the three Harvard losers fell on the final hole and the third, alternate Roger Wales, lost 3 and 2 to M.I.T.'s seventh man Don Anderson, who shot his season's best in a medal 79.

Heisler had no trouble beating M.I.T.'s Jerry Banner, 5 and 4, pushing his individual total to 9-1, the best on the team.

After trailing for the whole match, Bo Keefe missed a short putt on the final hole that would have given him a tie with Ken Smolek of M.I.T. Keefe's loss made him 8-2 in match play for the season.

Out of Slump

While Joe Tibbetts was racking up a substantial 3 and 2 margin over Mike McMahon of M.I.T., Tommy Wynne, the last of the Crimson winners, finally broke out of the slump he has been in since the Southern tour with a 4 and 3 trouncing of Tom Thomas.

Paul Oldfield lost one down to Greg Kast on the 18th. Oldfield and Wynne had been the marginal players on the squad this season.

Bruce Lopucki, who usually plays in the two or three positions, could not play.
