Norman, Okla. ? Fourth-year junior Catherine Carmichael blasted three kills in the final five points to force a fifth set and went on to fire a career-high 18 kills on the night, sending No. 21 Kansas University volleyball past Oklahoma, 25-16, 21-25, 13-25, 25-21, 15-10, on Wednesday in the McCasland Field House.

Kansas improved to 17-2 overall, 5-0 Big 12. OU fell to 14-6, 3-2.

“This team is pretty resilient,” Kansas coach Ray Bechard said. “Obviously, you don’t want to go down 2-1 on the road, but if you are, you have to come up with a plan. They did, and they executed it.”

Kansas sprinted out to an 8-1 advantage to start the fifth set. Carmichael, again, was clutch — cranking out five kills in the final set.

“It’s so awesome,” Bechard said. “If everybody could know where she started four years ago, I’m so proud of that kid, and she just keeps getting better and better. She’s a legitimate Big 12 attacker.”

Junior libero Brianne Riley dug a career-high 43 digs. Junior setter Erin McNorton collected her sixth double-double, with 54 assists and a career-high 22 digs.

Joining Carmichael in double-digits for kills were freshman outside hitter Tiana Dockery (14), sophomore outside hitter Sara McClinton (12) and fourth-year junior middle blocker Caroline Jarmoc (11).

KU will face No. 9 Texas at 7:30 p.m. Friday in Austin, Texas.
