The Lady Eagles started out slow and fell behind 10-1 but recovered for a commanding 73-42 victory over the Lady Indians.
"In each of our last four games, we have started slow and dug ourselves into a hole," said Purdy coach Grant Young. "Seneca came out on fire. I thought we did a good job of responding, and once we got rolling, we played pretty well."
Addy Roller turned in an amazing performance with 31 points, 7 assists, 4 steals and 6 rebounds.
Also scoring for Purdy were: Rachael Neill, 14; Mattie White, 11; Jayse Henderson, 5; and Katie Hughes and Kristyn Cornman, 2 each.
In the night cap, Purdy fell 63-58 to the Indians.
"We just got outworked on the boards tonight," said Purdy coach Tommy Egan. "Seneca pounded the ball inside and cleaned the glass on its misses. You can't give a team three or four tries in close to make one shot."
Seneca led 18-15 at the conclusion of the first quarter and grew the advantage to seven at halftime, outscoring Purdy 16 to 12 to take a 34-27 lead into intermission.
The Eagles came out of the locker room and promptly trimmed the Indians' lead to one at 38-37 but failed to score over the last three minutes of the third quarter as Seneca re-established a 47-39 lead heading into the fourth.
"The effort was there tonight," said Egan. "We fought hard but just came up short."
Purdy was led in scoring by Devon Bennett with 27 points, including eight 3-pointers.
Also scoring for the Eagles were: Drew Williams, 13; Cody Hall and Cameron Terry, 6 apiece; and Alex Haworth and Glenn Scott, 2 each.
The Eagles will be in action on Jan. 20, hosting Pierce City. The Lady Eagles begin play in the Stockton Tournament on Monday. Tipoff is set for 5:45 p.m.
