Lee (17-10), the Northern Region AAA champion, will play Petersburg (20-5), the Central Region representative, in a state semifinal basketball game Friday at 7 at James Madison University's Convocation Center in Harrisonburg.

South Lakes (23-3), the girls Northern Region champion, will play Warwick (24-3) at 2:45 Friday in the AAA state semifinal at Godwin Hall on the James Madison campus. Frank Cox (22-3) and George Washington of Danville (23-1) will play in the other semifinal at 1.

If Lee should win, it would face the winner of the game between Booker T. Washington (21-5) and William Fleming (23-2) in the final Saturday at 7.

Last week's Virginia Northern Region AAA final, in which Lee beat Stuart, 49-41, was a game filled with ironies. Lee Coach Charlie Thompson and Stuart Coach Ed Tiernan formerly coached together for three seasons. Tiernan was a varsity assistant to Thompson in 1981 when Lee won the state championship.

What's more, both Thompson and Tiernan played for Mount Vernon Coach Don McCool (Thompson played for McCool at Falls Church and Tiernan played for McCool at West Springfield) and in an earlier round it was Tiernan's Raiders who eliminated McCool's Majors. And so McCool, who probably had the strongest team going into the regional tournament, was the odd man out in the finale.

It was probably not much of a shock to McCool that Tiernan coached so well in the pressure-filled regional tournament. Three times, Tiernan had centered McCool's team to the state tournament.

None of the irony was lost on Thompson. "Ed went to the states three years as a player," said Thompson. "But he never won. The first time he went as a (assistant) coach in '81, he won when we (Lee) beat Booker T. Washington."

Lee finished the year with a 4-6 Gunston District record, but that does not bother Thompson. In 1981, when the Lancers won the AAA state championship, they finished third in the district.

Mount Vernon High School yesterday announced it will begin awarding a scholarship annually to its outstanding athlete in memory of Mary Siegrist Hinz, a former three-sport star for the Majors who was killed while on a Florida bicycle trip in August.

Mrs. Hines, a 1977 graduate who would have been 26 yesterday, was a standout in field hockey, basketball and softball.
