T.C. Williams boys and West Potomac girls needed the last few events of yesterday's Virginia AAA Northern Regional track and field championships at George Mason University to win the team titles.

The Titans won the boys title with 118 points. Lake Braddock was second with 96 and Chantilly (33) was third. West Potomac won the girls title with 63 points, beating Annandale (51) and T.C. Williams (49). The top six in each individual event qualify for next week's state championships, also at George Mason.

All-American Megan McCarthy of Robinson won the girls 1,600 meters in 5 minutes 4.02 seconds and the 3,200 in 11:18.43. McCarthy is ranked ninth nationally in the mile in 5:05.0.

T.C. Williams boys took the lead for good with strong showings in the 300- and 3,200-meter runs. The Titans earned 20 points in the 300 by finishing second, third, fourth and fifth. Michael Lacy of Lake Braddock won in 35.68 seconds, just ahead of Ezra Whorley (36.03).

The Titans earned another 14 points in the 3,200 when Mekonnen Berhanu (9:51.03) and Dawit Tekley (9:58.95) finished two-three. Aaron Linz of West Springfield won in 9:30.44.

The Wolverines girls took the lead for good in the 300 by earning 18 points behind the performance of all-American prospect Chrissie Edmundson and Tiombe Heard. Edmundson won in 41.76 and Heard (41.86) finished second. The Majors failed to earn a point.

To make matters worse, the Majors had no entry in the 3,200 and the Wolverines earned four points on a fourth-place finish by Amy Akstin (11:40.6).

The Titans received much needed points when James Porter won the boys 1,600 in 4:25.29, giving them a 53-47 lead. The Bruins had no entries in the event. Porter came to yesterday's meet ranked second nationally in the 800 (1:55.6) and fourth nationally in the 1,000 (2:32.5).

The Virginia high school league doesn't feature the 800 in the championship races, but Porter won the 1,000 in 2:34.56 to give T.C. Williams 10 more points.

The Bruins gained the lead for a short while by earning 18 points in the 500. Lacy won the event in 1:06.48 and John Petcu finished fourth in 1:08.66. The Titans had no entries in the event. Lacy is ranked third nationally in the 500 in 1:04.2.

In the girls competition, the Atoms earned 10 points in the 55 hurdles with their all-American prospect, Monica Crittenden, winning in 8.57. Crittenden is ranked second in the event on the East Coast.

"I want to run anything under 8 flat," she said. "But I'll take a win."

The Titans earned most of their points in the relays. They won the 1,600 in 4:05.24 and the 3,200 in 9:48.84. The Titans Kelly Mercer won the girls 1,000 in 3:02.03. Teammate Anne Kirpatrick finished second in 3:02.05.
