LaShawn Haythe of Silver Spring Track Club won both the 100- and 200-meter dashes in the girls 17-18 age division to lead all local finishers in today's 12th annual East Coast Invitational at Towson State University's Minnegan Stadium.

More than 2,200 athletes competed in the three-day event. Delayed for 30 minutes because of rain today, the meet was completed in 90-degree heat under hazy skies.

Haythe, a graduate of Gaithersburg High School who has just accepted a full scholarship from the University of Arkansas, ran the 100 in 12.11 seconds and the 200 in 22.94. In both races, Haythe never was challenged.

"LaShawn has one of the best starts that I have seen," said her coach, Ronald Ray. "She's at the point now where she can look to the side and accelerate, which is the true sign of a sprinter."

In one of the day's closest races, Dereck Moore of Northwest Track Club in Dayton, Ohio, edged Wayne Hefflin of Pittsburgh in the age 15-16 division of the 110-meter high hurdles. Moore finished in 14.90, Hefflin in 14.95. After jumping out to a strong start, Moore began to falter before finishing with a strong kick.

"I really had to push myself and catch up, because I knew I had the potential to take the race," said Moore, who won the 110 intermediate hurdles in 14.34.

"I felt Moore coming on and I began to worry more about him than going all out," said Hefflin. "That's what cost me."

Pam Doggett of Greensboro (N.C.) Pace won the 17-18 division of the 110-meter high hurdles in 14.09.

"I got out of the blocks slow, and that really threw me off," said Doggett. "I tried to pick up speed between hurdles, by using my arms more, and then I got myself back in."

Connie Ellerbe of Wilmington (Del.) Track Club won the 400-meter dash in the 17-18 division in 56.42.

"You have to know how to pace yourself," said Ellerbe, "so you will have something left in the end. Today I did just that."

Five meet records were set.

Top local finishers included Lisa Ostrom of Gaithersburg, who leaped 12 feet 11 inches to win the long jump in the 9-10 division. Torrence Owens of the District, finished second in the boys 9-10 division of the long jump with 14-5 1/2.

In the 11-12 division of the 800-meter dash, Vance Gilliam of Fort Washington won in 2:23.23, and Maryland residents finished 1-2-3 in the boys 14-15 division of the 1,500-meter racewalk. Don Augustine of Free State Fliers in Columbia finished first with a time of 8:16.5, followed by Brett Abildso of the Bowie Tracksters in 8:18.10, and Michael Jones of the Jaguar Track Club of Largo was third in 9:28.6.
