INGLEWOOD, CALIF., FEB. 19 -- Valerie Brisco and Greg Foster, among America's top hopes for gold medals in the Seoul Olympics, beat top Soviet athletes in tonight's Los Angeles Times Indoor Games.

Brisco, a triple gold medalist in the 1984 Olympics, won the women's 400 meters in 53.23 seconds.

Diane Dixon was second in 53.35, and the Soviet Union's Olga Bryzgina was third in 53.54.

Foster, running against a field that included Igor Kasanov, the Soviet Union's best high hurdler, won the 60-meter hurdles in 7.54.

Foster, the world's dominant high hurdler for most of the 1980s, nipped teammate Cletus Clark, who was clocked in 7.59.

Another American, Tonie Campbell, was third in 7.60, while Kasanov was fourth and last in 7.80.

Foster and the other U.S. hurdlers are the best in the world and figure to have a chance to sweep the 110-meter high hurdles medals in the Seoul Olympics this year.

Foster suffered a stunning disappointment in the 1984 Los Angeles Olympics when he finished second in the final to teammate Roger Kingdom.

Jackie Joyner-Kersee, currently ranked No. 1 in the world in both the heptathlon and the women's long jump, competed only in the long jump at the Forum, winning with a leap of 22-10 1/2.

Julie Rocheleau of Canada won the women's 60-meter hurdles in 8.03, with Lynda Tolbert of Arizona State second in 8.06, and Yolanda Johnson third in 8.27.

Juliet Cuthbert of Jamaica took the women's 60-meter dash in 7.23, followed by Diane Williams in 7.33 and Jennifer Inniss in 7.34.

Mike McRae won the men's long jump with a leap of 25 feet, 3 1/2 inches.
