Joe Bottoms of the United States took away Mark Spitz last world record today when he swam the 100-meter butterfly in 54.18 seconds, nine-hundredths of a second faster than the time recorded by Spitz five years ago at the Munich Olympics.
Brian Goodell of the U.S. set another world record with a 3:51:56 clocking in the 400-meter freestyle, improving on his own mark of 3:51.93 set during the 1976 Montreal Olympics.
American men won six of the seven-swimming events during the first day of the two-day meeting. The American women, who did less well, nevertheless were not unhappy with victory in two of seven events.
The East Germans are considered the powerhouse of women's swimming and do far better than East German men swimmers, a situation that still puzzles East German coaches.
American Alice Brown went after a world mark of her own in the 800 meter freestyle, but fell just short with a winning time of 8:35.20. Petra Thumer of East Germany, who holds the world record at 8:35.04, was a lagging second.
As the first day of competition drew to a close, it was apparent that the Americans had come to win and the East Germans were somewhat flat, despite their women dominating the European championships a week ago.
