In Koblenz, West Germany, Olympic champion Joaquim Cruz ran the world's fastest time for 800 meters this year for the second time in three days, 1:42.50. He ran 1:42.55 in Cologne on Sunday.

Sebastian Coe, whose 1:41.73 in 1981 stands as the record, lost to Cruz in Cologne and did not compete at Koblenz. Johnny Gray was second in 1:42.60, taking .36 off his own U.S. record.

Another U.S. record fell, to Henry Marsh in the 3,000-meter steeplechase. His 8.09.17 is a 1985 world best.

Steve Ovett, the 1980 Olympic 800 champion, had his comeback from illness spoiled just into the last lap of the 1,500-meter race. Ovett was just behind leader Jose Abascal of Spain when forced to pull out with what he said appeared to be a slight muscle tear in his right leg. Abascal won in 3:32.17.

Valerie Brisco-Hooks, the triple Olympic sprint champion, suffered a rare 1985 defeat, placing fourth in the 100 meters behind three fellow Americans led by Alice Brown in 11.02. Americans also dominated the men's 100, taking the first four places, led by Kirk Baptiste in 10.30.
