The varsity tennis team will play its last, and most important match of the season this afternoon at Yale, as both the Big Three and Eastern League titles will go to the winner.

Despite Yale's perfect record and amazing array of all sorts of champions, Crimson coach Jack Barnaby said yesterday that he expected a very close match. "We're definitely up for this one," he commented, and the Elis "will have to go some to beat us."

Dale Junta, whom Barnaby calls the best captain he's ever worked with, will meet Yale sophomore Don Dell in the first singles match. Dell is called by many the best college player in the East, having made an excellent showing in several big tournaments last summer.

In one of them, he beat Ashley Cooper in straight sets to reach the finals, where it took Hamilton Richardson five sets to defeat him. Like Junta, he has a powerful serve complementing beautiful ground strokes and quick reflexes at the net.

Not only strong at number one, the Bulldogs are so loaded with talent that Sam Schoonmaker, who played number three last spring, has been dropped to six to make room for sophomores Sandy Weiner and Gene Scott, both of whom have had good seasons.

Larry Sears will play at number two, where he will face Jon Clark, who lost in three sets to North Carolina's Steve Bank. Sears defeated Bank when the Tarheels played in Cambridge, and has been on his game all year, except for his loss to Tom Richardson when his game failed to jell.

As a result of his victory Monday over Tim Gallwey, Ned Weld will move up to the number three spot, encountering the more experienced Tom Freiberg. Freiberg was first man last year, another indication of the Elis' strength, and will be Weld's toughest opponent of the year. However, the stocky junior has come a long way since the beginning of the season, and has shown great endurance and hustle.

Gallwey, who has also improved tremendously since April, will meet Weiner at number four, and Al Goldman will take on Scott at number five. Rounding out the first six will be Fred Vinton.

The first three varsity doubles combinations will be Junta and Sears, last year's intercollegiate champions, Gallwey and Vinton, and Weld and Bill Wood.
