Lancaster, Texas, has been kind to the Sooners in recent years.
Oklahoma has dipped into the school's deep recruiting pool for Demontre Hurst and Quentin Hayes.
Oklahoma went back to Lancaster for one of its final commits of the 2013 class, with cornerback Dakota Austin committing Feb. 2.
Austin (5-foot-11, 167 pounds) isn't the highest-rated defensive back in the Sooners' class, but the commitment quickly drew praise from others in the class.
Linebacker commit Dominique Alexander of Tulsa Washington tweeted about Austin's commit just after it was made public.
“Say what you want on rankings and stuff. But Dakota Austin is Cold. That boy Lockdown. Good pick up,” Alexander posted.
The pair attended the same OU camp during the summer long before either committed to the Sooners.
Austin picked the Sooners over Nevada and UNLV and also had offers from Indiana, Texas Tech, Tulsa, Utah State and UTEP.
The day Austin committed was a fruitful one for the Sooners with Lancaster players.
Hours after Austin made his commitment to OU, Lancaster junior Vontre McQuinnie committed for the 2014 class after a visit for junior day.
