Led by strong performances by George Keim and Kevin O'Connell, the Crimson aquamen rallied to a second-place finish after the second day of the Eastern Seaboard Swimming Championships in New Haven.

Keim bested the field in the 100-yd. butterfly with a time of 51.6 seconds. Tim Neville added more points for Harvard with a fourth-place finish at 52.2 seconds. John Craig finished eighth in the event with a lifetime best of 52.6 seconds.

O'Connell turned in a strong 53.3 time to finish third in the 100-yd. backstroke. Excellent performances by Duncan Pyle, who finished sixth; and freshman Malcom Cooper, who turned in a lifetime best 54.1 seconds for seventh place, completed a solid Crimson showing in the event.

Coach Ray Essick chose not to enter any swimmers in the 100-yd. breaststroke since Ted Fullerton, the Crimson's premier breaststroke, took the semester off to train for the Olympics.

Peter Tetlow and Paco Canales added points to the Crimson tally in the 400-yd. individual medley. Tetlow recorded a stunning 4:14 in the preliminary heat, and finished sixth in the finals at 4:17.5. Sophomore Canales was tenth with 4:17.9.

Later in the meet, Canales anchored the Crimson 800-yd. freestyle relay. Cooper, Wes Raffel, Myles Standish and Canales placed sixth with a time of 7:02.4.

Raffel raced to his best time this year in the 200-yd. freestyle. He finished a respectable seventeenth in a tough field of more than 50 competitors.

Crimson diving should be crucial in today's competition. Following strong performances in the one-meter diving last Thursday. Dave English, Mike Toal, Roger Johannigman and Tom Cook all qualified yesterday for the three-meter event.
