The Lady Eagle utilized three scoring runs to extinguish any thoughts Miller might have had of an upset.
The Lady Cardinals led 4-2 in the opening minutes of the game before Purdy responded with a 9-0 run to take an 11-4 lead. The Lady Eagles concluded the first quarter with an 18-6 advantage.
"Any win in districts is a good win," said Purdy Head Coach Grant Young. "We had too many turnovers to start the game, but we were able to regroup and regain control."
The Lady Eagles outscored Miller 15-11 in the second quarter to lead 33-17 at halftime.
Purdy opened up a 59-26 advantage at the end of the third quarter.
The Lady Eagles were eight for 18 from the three-point line and snagged 41 rebounds.
"We ran the floor well in the second and third quarters," said Young. "Our pressure defense really gave Miller fits and led to some easy baskets and extra possessions for us. We are a really hard team to guard when our outside shots are falling."
Addy Roller led the Lady Eagles in scoring with 21 points. Also scoring for Purdy were: Brooke Swadley, 14 points; Shelby White 11 points; Shelby Scott, 8 points; Audrey Patton and Rachael Neill 3 points; and Kristyn Cornman, 2 points.
Purdy faces Liberal in the district championship game on Friday in Carthage. Tipoff is set for 7:30 p.m.
The Purdy Eagles season came to an end Wednesday with a 59-48 loss to Wheaton.
"Obviously, it's not the end that we had envisioned for our team," said Purdy Head Coach Tommy Egan. "Our boys played hard. The shots didn't fall. The effort was there."
Purdy led only twice in the game, 2-0 and 10-9. Wheaton led 12-10 at the end of one quarter of play and opened up the second period with a 7-0 run to help the Bulldogs take a 29-17 advantage into halftime.
Purdy would close the gap to 52-44 with 2:25 left in the fourth quarter but wouldn't get any closer.
"I told our juniors that we need to get stronger and quicker in the offseason," said Egan. "We are losing four really good seniors and it will be hard to replace what they have meant to this team. I have no doubt that we will get to the gym and work hard to improve for next year."
Landon Terry led the Eagles in scoring with 18 points. Also scoring for Purdy were: Devon Bennett, 9 points; Alex Haworth, 6 points; Drew Williams, 5 points; Cody Hall, 4 points; and Riley Veith, T.J Farris, and Garen Nelson, 2 points each.
Wheaton was led in scoring by Joey Bartkoski with 17 points. Also scoring for the Bulldogs were: Sean Goostree, 14 points; Jacob Beck, 11 points; Justin Yeary, 10 points; Jeffery Musick, 3 points; and Kyle Robbins and Jesse Mitchell, 2 points apiece.
