Iowa State remains the only school in the country with undefeated men's and women's basketball teams.
Each squad is 13-0 and off to the best start in school history.
Coach Fred Hoiberg's men's team is ranked ninth heading into Tuesday's home game with No. 7 Baylor.
The women are ranked 11th, their highest position since 2002, after winning 82-75 in overtime at Oklahoma on Sunday.
Iowa State athletic director Jamie Pollard says the strong starts by both teams is a unique situation that has excited the fan base.
