AMES, Iowa (AP) — Iowa State's lack of depth made its hopes for a regular season Big 12 title unrealistic.

Perhaps the postseason will be kinder to the 21st-ranked Cyclones.

Iowa State (21-10, 10-8 Big 12) will begin its quest for a third straight conference tournament title Thursday against third-seeded Oklahoma (24-6, 12-6), ranked sixth nationally.

The Cyclones are the sixth seed — which could be lower than the one they'll receive for the NCAA Tournament if they replicate their previous success in Kansas City.
