Casey Morris scored a game-high 13 points and now has 988 career points.
Tech (10-2) won its 48th consecutive non-conference game at home, dating back to its last regular season loss to the Cougars on Dec. 4, 2007.
Senior Christine Hyde (12), senior Chynna Brown (11) and junior Kelsi Baker (10) ended the game in double figures while the other seven active players on the roster also scored. Baker finished in double figures for the eighth time in nine games.
"I think you have to be pleased, anytime you hold someone in the thirties, percentage-wise, and you can score 80 points coming off the break," head coach Kristy Curry said. "I love our balance. We had four in double figures, and then seven, seven, seven, and nine.
"What they all have to understand is that they are all going to be called upon and everybody on that bench has a chance to impact the game. I think we know that together it's going to take all of us and I was pleased with how they all showed up and played today."
Houston (5-7) battled back and forth in the first 10 minutes of play as Morris scored five of Tech's first seven points. The Cougars built an 11-7 lead before the rest of the Tech offense started to catch fire.
Tech went on a 20-9 run to build a seven-point lead late in the first half before doubling it to go into the break up 38-24 - thanks in large part to Morris' 3-point shooting and 13 first-half points.
"I think that usually works best when I come out strong and shots fall," Morris said. "I think that just makes my confidence build. But even when I do come out and miss I think I need to still keep on shooting, just like anyone else on our team who is a shooter they just need to keep on shooting just like they've been preaching throughout the season, but it is always good to start off strong."
She would continue to contribute on offense with rebounds and assists in the second half as Tech scored on 11 of its first 12 possessions. The Lady Raiders went up by as many as 34 points while hitting 17 of 28 in the final half (60.7 percent) and overcame 23 turnovers - their most in a game this season.
And it wasn't just the starters producing this time. Tech's bench contributed 35 points, including a season-high seven in the second half by senior Mary Bokenkamp. Amber Battle added seven points and seven rebounds along with Jackie Patterson's nine and Shauntal Nobles' seven.
"I think coming off the bench we all try to have the most energy as possible coming into the game," Bokenkamp said. "We were all together on the bench in the first half watching and trying to keep our minds focused so when we got our chance in the second half we wanted to make the most of it. We just tried to come out with a lot of energy defensively and rebounding and baskets happened to fall as well, so it worked out."
Tech will head to Stillwater to take on No. 14/13 Oklahoma State (10-0) at 7 p.m. CT on Wednesday. The Cowgirls enter the game with the nation's longest winning streak - 16.
