In a game featuring a seesaw second half, 17th-ranked Potomac overcame a 13-point fourth-period deficit to defeat Gwynn Park, 64-60, last night in a Prince George's AB girls basketball game at Potomac.

The Braves (3-0) began the game missing five of their first six shots, but led, 30-29, at halftime. Then defending league champion Gwynn Park (1-1), with 5-foot-4 junior guard Monic Holbeck scoring from all angles of the court, went on a 22-8 rampage to lead, 51-38, at the end of the third period.

In the fourth, it was Gwynn Park's turn to wilt. Under full-court pressure, the Yellow Jackets turned the ball over, allowing Potomac renewed life. Still, Potomac's rally might not have been successful had it not been for the sterling performance of 5-11 junior Shelley Steward, who finished with 16 rebounds and a game-high 36 points.

Steward led a 15-0 run to a 53-51 lead, and scored six straight points to turn a deficit into a 62-57 lead.

The first half had been a showcase between Holbeck, who scored 18 of her team-high 30 points before halftime, and Steward, who got 11 of her 12 points in the first period. But Steward drew her third foul minutes before intermission and did not assert herself the rest of the way.

With her team trailing by 13 points entering the fourth, Steward was relentless, making her way in the lane to score off a power move to narrow it to 51-40. Beset by full-court pressure, Gwynn Park turned the ball over and Stephanie Evans sank a foul shot for Potomac to make it 51-41.

Gwynn Park tried to get back into sync, but the Braves went ahead, 52-51, with 4:07 left on Steward's turnaround in congested traffic in the lane.

Steward made a free throw, but Gywnn Park's India Petite scored on an uncontested layup to tie it, 53-53.
