For the fifth straight year, a member of the Stross family will be honored at the annual Washington Post All-Met high school awards luncheon, at noon Friday at the Washington Hilton and Towers International Ballroom. Barbara Stross, a senior and two-time All-Met selection from Wootton, will be honored along with nearly 300 others for their athletic achievements in the 1989-90 school year.

Bobby Mitchell, an assistant general manager of the Washington Redskins, will be the guest speaker. Mitchell, a 1983 inductee in the NFL Hall of Fame, joined the Redskin personnel staff in 1969, just after a very successful 11-year professional career with Cleveland and Washington.

Former Navy all-American and the NBA rookie of the year David Robinson will receive the All-Met Distinguished Achievement Award.

Two other All-Met honorees -- Tommy Burns, a football/baseball player at Bishop McNamara, and Whei Wong, a softball player at Bishop O'Connell -- will be presented with the Michael L. Trilling Award. Trilling, who died in October 1988, coordinated The Post's high school coverage for 17 years. The award named for Trilling is given to the male and female students who best exemplify academic and athletic achievement along with outstanding leadership qualites.

The Post will present awards to athletes in 23 varsity sports, including recent additions, boys and girls lacrosse. Archbishop Carroll's Lawrence Moten is the only area athlete to be selected first team All-Met in football and basketball in both his junior and senior years.

Barbara Stross is the third sister to be named to the All-Met volleyball team. Older sister Bev, a chemistry major on volleyball scholarship at Duke, was selected in both her junior and senior years at Wootton. Gretchen Stross, an International Business and Finance major at Georgetown on volleyball scholarship, was selected in her senior year. Barbara Stross has signed a volleyball scholarship to Pepperdine.
