Williams hasn't beaten Harvard's tennis team since Billy Hayes's Balled of Davy Crockett was breaking records stop the Cashbox Weekly National Blockbuster Chart. It was a damned good tradition, and one that the Crimson was cautious to preserve yesterday when it travelled to Williamstown by automobile to meet the Ephmen inside Lansing-Chapman Hockey Rink.

Playing brilliantly on the Uniturf overlay surface, Harvard swept five singles and all three doubles matches in straight sets and went on to a convincing 9-0 victory, its third straight since the "aesthetic trauma" at Columbia-Princeton two weekends ago.

Williams was not the most terrifying of opponents, but the Ephmen had whipped both MIT and Army by 8-1 counts, and they had the added advantage of playing on a familiar court, with a type of surface that Harvard had not been exposed to this season.

But the Crimson had few problems throughout the ladder, as only co-captain Chris Nielsen was forced into a third set. Nielsen rebounded from a 6-3 loss in the opening set to defeat Charlie Kieler, 6-0, 6-1, at the number six position.

Elsewhere, Harris Masterson won his third straight match after a disappointing start early in the season, disposing of Williams captain Chris Warner, 6-3, 6-2, at the top spot. Classmate Ken Lindner swept Bill Simon at number two, 6-2, 6-4, while freshman John Ingard handed Ephman Dick Small his first loss of the Spring, 6-3, 6-0, at three.

Randy Barnett whipped Jim Marver at number five, 6-3, 6-1, and junior Tom Loring captured the match-winning fifth point with a 7-5, 6-1 triumph over Peter Talbert at four.

The doubles, as you might expect, were not exactly an exhausting affair. Lindner and Masterson, perhaps the top unit in the EITA this Spring, swept Warner and Small at number one, 6-3, 7-5, and the Ingard-Nielsen team, gradually rounding into top form, handled Simon and Talbert at two, 6-4, 6-2. Loring and Barnett completed the enterprise at three, 6-3, 6-2, over Marver and Kieler.
