Purdy trailed the entire first half against Sparta. The Eagles deficit was five points (13-8) after the first period and 31-19 at halftime.
"We were sluggish from the start," said Purdy coach Tommy Egan. "We had too many turnovers, the defensive intensity wasn't there, and we had poor shot selection. Sparta played really solid defense and controlled the boards in the first half."
The momentum from the third quarter carried over into the fourth frame as the Eagles outpaced Sparta 19-8 to earn the victory.
"I can't emphasize enough how proud I am of this team and the way they responded to adversity," said Egan. "This is the biggest deficit we have overcome in our three years together. We hope to build on this game as we go forward in the season."
Purdy scorers: Cameron Terry, 17 points; Tyler Scott, 15; Brent Cornman, 12; Keevin Walker and Alex Mareth, 4 each; and Glen Scott and Austin Hancock, 2 apiece.
For his efforts, Terry was named to the All-Tournament team.
In the semifinal, of the Clever Tournament, Purdy fell 60-50 to the host Bluejays.
The Eagles started the game red-hot jumping out to a quick 13-4 lead.
A timeout by Clever couldn't kill the Purdy scoring machine as the Eagles forced seven Bluejay fouls and outscored their hosts 20-10 in the first period.
The veteran Clever team wouldn't go away and responded in the second quarter.
A 3-point play by Colton Pemberton ignited a 16-6 spurt that sent both squads into half tied 28-28.
"I thought we started the game really loose and focused," said Egan. "Clever is a very solid program. They made the adjustment and really clamped down."
Purdy was plagued by turnovers, foul problems and empty possession in the third period but only trailed 41-37 to start the fourth period.
Mareth hit a short jumper with 3:49 remaining and tied the contest at 48-48. However, Clever closed out the game on a 12-2 run to earn the victory.
"I really felt that we got the type of shots we wanted in the fourth period," said Egan. We just couldn't get them to go in the basket. I think we wore down and ran out of steam. We will use this game to get better."
