Anna Prins scored a career-high 32 points and Iowa State advanced to its first Big 12 tournament championship game in six years, beating Oklahoma 79-60 on Sunday. The Cyclones (23-7) trailed only once. After Joanna McFarland's 3-pointer put Oklahoma up 10-7 less than 4 minutes into the game, Brynn Williamson's 3-pointer opened a 17-0 run when five different Iowa State players scored. Iowa State, which kept a double-digit lead after that 6-minute spurt, plays No. 1 Baylor (31-1) on Monday night.
