Neville Hayes, former Olympic medalist and the varsity swimming team's undefeated butterfly star, has been named to a place on the NCAA All-America swimming team.

A sophomore from Australia, Hayes won a silver medal at the Olympic Games in Rome in 1969 and held the world record in the 220-yard butterfly from 1960 to 1962. He is Harvard's second swimming All-American this year; senior Danny Mahoney was named to diving team at the NCAA championships in Iowa last month.

The All-America team in swimming is chosen on the basis of the fastest ten times verified and submitted to NCAA officials by coaches during the season. Until he became sick from a virus shortly before the Eastern championships in March. Hayes had consistently gone better than two minutes in the 200-yard buterfly, faster than anyone else in the East.

Hayes's fastest time was a 1:57.4 clocking against Navy in December. By the time of the National championships in March, this was still the fourth fastest time in the country. Without illness, Hayes could have been expected to go several seconds faster in the Eastern and NCAA's. Next year he will again be in a class by himself in the East, and probably one of the nation's best as well.

Hayes learned of his achievement for the first time at the Swimming Awards Banquet last week, which was sort of a testimonial dinner for seniors Mahoney and Dave Abramson, Mahoney won three wards: the William J. Brooks diving award, the Friends of Harvard Swimming Award for an undefeated senior, and the Stowell award for the greatest improvement in his college career.

Abramson, the team captain, was honored with the Hal Ulen Award, the varsity's highest honer, and sophomore breast stroker Bob Corris received a trophy as the highest point total scored during the season.
