St. Anthony's bid to win two girls basketball tournament titles this week ended unexpectedly last night when the Tonies claimed foul and walked off the court in their semifinal game against DuVal in the George Mason University Invitational.

After trailing, 57-47, with 2:05 to play, the Tonies closed within 57-53 on Virginia Toler's three baskets. St. Anthony's forced a jump ball on DuVal's inbounds play, but the timer failed to stop the clock. The clock finally was stopped at 31 seconds and St. Anthony's Coach Daryl Tolliver asked that the clock be set back.

When officials refused to do so, Tolliver took his team off the court.

The 57-53 defeat was St. Anthony's first after eight victories.

Earlier in the day, St. Anthony's rallied after a poor first half and scored 25 third-quarter points to beat H.D. Woodson, 50-32, in the Eastern Board of Basketball Officials girls basketball tournament at McKinley.

Although St. Anthony's managed a 20-12 halftime advantage, it played poorly, missing several easy shots and committing 10 first-half turnovers.

Following a lengthy halftime talk by Tolliver, St. Anthony's began the second half by scoring 10 straight points and taking a 30-12 lead with 6:06 to go.

"I think the team was looking ahead to the game tonight," Tolliver said. "I reminded them that we had to play the games one at a time."

In the second half, St. Anthony's ran its offense well and forced Woodson (0-1) into several turnovers.

The two main scorers in the big third period were forward Toler (seven points) and center Britt King (six points). Toler, averaging 23 points per game, was held to four first-half points by a tight box-and-one defense. She finished with 13 points, and King led all scorers with 15 points. She had 12 rebounds.

Woodson center Audrey Prophet carried the Warrior offense early, scoring nine of her 13 points in the first three quarters. But after the 5-foot-11 center tired, St. Anthony's breezed to its eighth straight victory.

In other quarterfinals of the Eastern Board event, Dunbar defeated Anacostia, 65-32; La Reine beat McKinley, 55-43; and Ballou beat St. Cecilia's, 52-32.

Dunbar, which took a 25-0 lead, got 17 points from Karen Alston. Teammates Trina Steadman and Dana Hill had 13 and 12 points, respectively.

Brenda Payne scored 17 of her game-high 21 points in the second half as La Reine pulled away.

Joanna Millhouse scored 34 points to lead Ballou.

St. Anthony's will play Dunbar in one semifinal at 2 p.m. today.
