Ingram had a golden opportunity to win in regulation when they drove to the Edna 14-yard line, but Carranza's 31-yard field goal attempt sailed wide right with 3:34 remaining. Neither team could muster another scoring threat before the end of regulation.
The Mountaineers shot 46.6% from the field compared to 45% for McMurry. Schreiner held a 42-39 edge on the boards.
The loss dropped Schreiner to 1-5 overall and 0-1 in SCAC play, extending the Mountaineers' losing streak to five games.
The victory improved the Warriors to 7-5 and moved the program's playoff record to 6-8 overall. Ingram will face Edna at a neutral site on Nov. 28 in the third round.
The Mountaineers got 21 kills from junior Gianna Hilliard, who hit .232 on the day, but they could not slow Colorado's offense.
The third-seeded Mountaineers (23-6, 13-3 SCAC) advance to their first conference championship match in program history. They will face Colorado College at 3 p.m. Saturday.
The quick turnaround means Schreiner will focus on rest before facing Hendrix.
Now Ingram waits. The Warriors will play the winner of Raymondville (10-0) and Orange Grove (8-2). Those two teams play tonight.
"Our defense did an outstanding job of dominating the game," Schreiner head coach Keith Allen said. "We were able to get five takeaways, a defensive touchdown and a safety—all while shutting them out."
Schreiner dropped to 21-6 overall and 12-3 in SCAC play, while Colorado College improved to 18-7 and 10-4 in the conference.
