Dallas Highland Park was once the No. 1 team in Class 5A, but had since dropped to No. 25, so the Prosper Lady Eagles knew they couldn’t take them lightly despite holding a 2-0 lead in their area round match on Nov. 3.

Highland Park stormed back to take the third and fourth game before Prosper outlasted to win the thriller in five sets 25-20, 25-19, 19-25, 23-25, 15-9.

The Lady Eagles won their 40th game of the season (40-7) and advanced to the 5A Region II quarterfinal where they take on Frisco Wakeland on Tuesday, 7 p.m. at McKinney Boyd High School.

Prosper was able hold down the lead in the first as the Lady Scots couldn’t get over the hump. Sophomore Ciera Hecht and junior Haley Killinger had three straight kills as Prosper had a 22-17 lead.

In the second set, Prosper jumped out to 10-4 and 12-6 and again, Highland Park inched its way back, but couldn’t quite get there.

Senior Abby Gargus tied it at 4-4 in the third set and Killinger’s block gave the Lady Eagles a 10-9 margin.

Highland Park scored eight of the next 10 points for a 17-12 lead then led 24-16 before taking the game.

Prosper found itself down five in the fourth set then came back to within 18-16 after a block from junior Hope Gramly. The Lady Eagles continued their run with another block, a kill from Hecht and two kills from Killinger to take a 21-19 lead.

But the Lady Scots came back with a 6-1 run to tie the match at 2-2.

Killinger started Prosper’s fifth set with the first three kills and 3-2 lead. Junior Chloe Hancock and sophomore Madi Whitmire extended it to 6-3. Killinger served up an ace at 10-6 and Hecht helped finish it off for the area championship, the program’s fourth straight and 11th since 2002.

The Texas Tech commit Killinger had a whopping 26 kills and 17 digs while Hecht put in a rare 20-20 game with 23 kills and 26 digs. Gargus and Whitmire set great games with 31 and 22 assists, and sophomore Kylie Mote added 21 digs. Gramly was big at the net with a team-high six blocks.

Prosper swept Frisco Liberty in the bi-district round, 25-20, 25-14, 25-21.
