Yale's awesome swimming forces took five out of seven firsts Saturday night to win the unofficial team championships in the Easterns by an overwhelming margin and serve notice that they will be the team to beat in he Nationals two weeks hence. Only the Crimson's Chouteau Dyer in the 100 and Army's Frank Knight in the three-meter dive were able to break the Eli stranglehold.

Although no team championships are awarded in the Easterns, using the official NCAA scoring system (7-5-4-3-2-1 for the individual events, and 14-10-8-6-4-2 for the relays) the Elis would have been first with 165 points, followed distantly by Harvard with 53, Syracuse with 31, and Amherst and Army with 25 each.

Tim Jecko got the Elis off to a flying start by setting new meet and pool records in the 100 yard butterfly with a time of 54.9 seconds. One has come to expect this of Jecko, who became the second man in the history of the Easterns to set meet records in three different events. (The first was another Yale great, John Marshall.) But pleasantly surprising was the fine performance of Crimson sophomore John Hammond, who came from behind to edge out John McGill of Syracuse in 56.8 seconds. Although this time cannot be recognized as a new Harvard record, since Hammond didn't win the race, it beats his listed record by 1.8 seconds and places him among the top 100-yard butterfly men in the country.

A1 Chapman (58.3) of Brown, Bill Clinton (60.2) of Yale, and Bill Caprio (61.0) of Colgate took fourth, fifth, and sixth respectively.

Probably the most satisfying event for Crimson fans was the 100 yard freestye, for captain Dyer gained a fitting revenge over Amherst sprinter Bob Keiter, who had beaten him in the 50 the day before. This time Dyer got an excellent start, and the smooth-stroking senior led all the way to win by a body length in the meet-record time of 49.4. Keiter, who was clocked in 50.8, finished half a length ahead of Yale's fading sprint star, Rex Aubrey (51.4).

The Elis' Dan Cornwell (52.2) finished fourth, while Harvard's Pete Macky, who had edged Roger Clifton in a swim-off to get into the final, finished a surprise fifth in 53 seconds flat. Anders Anderson (53.3) of Navy took the final position.

The Crimson's final scores came in the 400-yard medley relay and the three-meter dive. In the relay, the Harvard team of Bill Murray, Sigo Falk, Hammond, and Dick Seaton (3:59.3) finished second to Yale (3:58.3) after a see-saw struggle Murray and Falk lost about a length of open water to the Elis, but Hammond churned this into a six yard lead. It was not enough, however, for the fast-closing Aubrey caught Seaton after 60 yards and led him home by half a length.

In the dive, Frank Gorman finished strong, and, aided by some unusually poor diving on the part of some of his opponents, jumped from eighth place to third. Frank Knight (409.6) of Army won the event, while Warren Frischmann (381.25) of Syracuse finished second. Army's Duke Gerhardt (329.45), Princeton's Alan Routh (318.85), and Yale's Jack Erickson (306.2) took the last three places.
