"It was an intense competition in an intense atmosphere," said Oklahoma head coach K.J. Kindler. "I thought we did well at staying focused and doing what we know how to do."
OU put together its best bar routine of the year, using back-to-back-to-back scores of 9.9 by Erica Brewer, Keeley Kmieciak and Haley Scaman to post a 49.450, a season high for the Sooners and the second-best score on bars of any team in the country entering this week. Rebecca Clark and Taylor Spears rounded out the Sooner scorer by each totaling 9.875 scores.
"We stuck landings," Kindler said. "It's something we really focused on this week, made some adjustments, and I think it showed."
Individually, Lauren Alexander posted the highest score of the day of any competitor on beam, earning a 9.975 on scores of 10.0 and 9.95. The score was Alexander's career high and the highest score on any apparatus by a Sooner this seaosn. Spears added a 9.875 on the event, while Kmieciak, Brewer and Mooring all totaled 9.825 scores.
"Anytime an athlete gets a 10 it's a very special moment," said Kindler of Alexander's effort. "That tells you that was an extra special routine."
Oklahoma led off the night on vault, scoring a 49.225. Scaman had a team-high 9.9, her career best, and was joined by Spears and Kmieciak who each scored a 9.85 apiece.
