Estancia ended Costa Mesa's 32-game Pacific Coast League winning streak, beating the Mustangs, 50-45, in a girls' basketball game Thursday at Costa Mesa.
The loss dropped the Mustangs to 12-5, 2-1 in league and left University (10-4, 2-0) in sole possession of the league lead.
Estancia led all the way and was up by 11 with a minute to play before two Costa Mesa three-pointers closed the gap.
"We needed that one," Estancia Coach Russ Davis said.
Estancia (10-4, 1-2) had lost its first two league games by a total of 11 points, and Davis noticed a pattern.
"Against both University and Laguna Hills, we played a great first quarter on defense and then fell off," he said. "We only played two good quarters (in the two games) and we were still in both games. Tonight we needed to play four good quarters to win."
The Eagles again were strong in the first quarter, building a 14-7 lead after one quarter and extending that lead to 20-9 with five minutes left in the half. Estancia made 10 of its first 15 shots; Costa Mesa was three for 22 from the field in the first half.
The Mustangs never got untracked in the second half. Costa Mesa pulled within six at 29-23 early in the third quarter, but center Corri Lurmann picked up her fourth foul and sat down, and Estancia opened up an 11-point lead, 36-25. The Mustangs never got closer than five in the final quarter.
Lurmann led all players with 14 points and 12 rebounds despite missing much of the middle two quarters with foul problems. Jill Black paced Estancia with 13 points and 11 rebounds.
