Delcastle's Da-qira Lancaster-Navarro scored a game-high 16 points as the Cougars won their first DIAA Girls Basketball Tournament game in 10 years with a 42-34 win over Wilmington Charter.
The Cougars were looking for their first post-season win since winning the 2009 championship, when their current head coach Jaquetta (May) Harmon was on the court.
There might have been some nerves early, as both teams struggled making shots from the floor in the first half.
Wilmington CHarter was getting the best of it, as Emma Brown's three-pointer and Ashley Steiner's basket after a pump fake had them ahead 12-4.
Delcastle responded with a 7-2 run to and the half, with Taylor Pittman slicing to the basket for two points to get the hosts within 3 at intermission.
They tied the game at 14 early in the third quarter, but Charter again went up by 3, before Delcastle went on the crucial run.
Buoyed by the defense of center Emani Lucas-Davis keeping the Force from getting early shots, she scored off an offensive rebound to get them within a point, and then forward Taliyah Duvan scored off a Pittman assist to tie the game.
Duval and Lucas-Davis added two more second-chance baskets, and Delcastle had an 11-3 run and 25-20 lead going into the fourth.
Lucas-Davis netted yet another putback to start the fourth to give the Cougars their largest lead at 28-20, but Nia Anderson and Charter wouldn't go away.
Anderson hit a pair of long three-pointers in the final minute, but they could not get any closer than four points, as Lucas-Davis supplied several crucial blocks in the final minutes to slow down the Force's comeback.
Pittman scored 12 points for Delcastle, who advances to face No. 3 Conrad Friday night at 7 p.m. on the road.
Anderson scored 13 points, while Brown had 12 for Wilmington Charter.
