AUSTIN -- Britton Wilson of Arkansas eyed a historic NCAA Championships double. 

Rashidat Adeleke of Texas said, "not in my house."

The Longhorn junior surged out of the final turn and left no doubt down the stretch, winning the 400m in a meet-record 49.20 at Mike A. Myers Stadium.

Adeleke lowered the meet mark of 49.36 set in the semifinals by Wilson. 

"Coming over (to the track), we were just so excited," Adeleke said "Really good vibes (on the team), we all really enjoy each other. I feel like we bounce the momentum. When my teammate won, it made me more excited for my own race."

The Arkansas junior was bidding to become the first athlete in history to win the 400m and 400m hurdles titles at the same NCAA Championships. She will contest her second event in about 30 minutes

Adeleke's victory is a major accomplishment for the Texas track and field program. She is the first Longhorn to win the women's 400m at the NCAA Outdoor Track & Field Championships since Sanya Richards-Ross in 2006.

"(The race) was kind of a blur," Adeleke said. "I just went out trusting myself. Not really sure what I went through the 200 (mark) or anything, I just put myself into position coming into the home stretch, and it was the kick at the end, which is something I've been doing well all season."
