Preseason All-American Danielle Robinson totaled a game-high 19 points and six steals to lead a scrappy Sooner defense that scored 40 points off Lady Eagles' turnovers.
"We want to be able generate our offense with our defense and we did a good job of that," OU head coach Sherri Coale said. "We got a little greedy and either gave them an angle to the rim or fouled. But I liked their aggression. I like the way, particularly, Danielle (Robinson) was getting after the ball. I like the way my big girl Joanna (Mcfarland) goes diving after the loose ball and makes a play. Lauren Willis comes in and flies around, dives on the floor and gets a loose ball. So I thought there were some really good things in that regard in the effort category."
Oklahoma Christian kept the game close for the better part of the first half until the Sooners, spurred by four points from senior Lauren Willis, opened a 10-0 run to take a 28-14 lead.
OC's Katy O'Steen capitalized on a Joanna McFarland foul and Robinson turnover to score four for the Lady Eagles, but Robinson countered with two fast-break layups as the Sooners scored eight straight before an OC field goal made the score 41-21 at halftime.
Robinson scored the first seven points of the second half as OU ran away with a 13-0 run.
OU broke in six newcomers after returning just eight from last year's Final Four team.
Freshman guard Aaryn Ellenberg started aside Robinson, Jasmine Hartman, Lyndsey Cloman and Joanna McFarland. Ellenberg scored 10 points and grabbed six boards.
"This is the first time I've seen (Aaryn) kind of nervous," Coale said. "I haven't seen her bothered by one thing yet, so maybe it was a couple thousand people in the Lloyd Noble Center that bothered her a little bit.
"One of the things I love about Aaryn is her confidence. She knows she can score, she's not going to turn down good shots. She's going to keep getting after it and she's going to be a big-time player."
Junior college transfer Jelena Cerina scored OU's first field goal and freshman Morgan Hook was first off the bench and provided an immediate impact, sinking back-to-back 3-pointers as part of a perfect first half of shooting.
With a combination of Nicole Griffin, Morgan Hook, Jacqueline Jeffcoat, Kodi Morrison and Alexann Yancey on the floor, the Sooners closed the game with a 16-0 run.
"We just tried a lot of different combinations," Coale said. "It was sloppy and we didn't look in sync and part of that is my fault. We haven't worked on zone offense at all. We were trying to learn it on the fly and had a lot of strange combinations at times. There were some good things. We were on the floor after every loose ball, we made a lot of good effort plays, did some good things in transition. Morgan (Hook) came in the game early and knocked down a couple 3's and showed what she can do to stretch defenses. I thought we had good performances from our backup post guys -- Jelena (Cerina) came in and got going and Nicole (Griffin), at the end, established herself a little bit. There were good moments but too many turnovers overall."
OU's post players connected on 13 of 16 field goal attempts as the Sooners shot a combined 59 percent from the field, while holding OC to a 27 percent success rate.
Senior forward Carlee Roethlisberger sat out the game for precautionary reasons with a minor ankle sprain.
