The Oklahoma Sooners earned the top spot in the AP and the coaches poll on Monday afternoon, marking the first time the Sooners have been ranked at as the No. 1 team in the country since the end of the 1989-90 regular season.
That year, Oklahoma won the Big 8 Conference tournament and made the second round of the NCAA Tournament.
Oklahoma earned its first in-season top rankings since 1989 but will head to Hilton Coliseum at 8 p.m. Monday for a matchup against Iowa State - a team Oklahoma hasn't beaten on the road since 2011.
Oklahoma has played Iowa State just once as the No. 1 team - a 126-97 victory in 1989.
