AMES, Iowa – Iowa State struggled from the field and at the line but prevailed in overtime against a gritty Missouri squad Tuesday for a 66-59 victory in Hilton Coliseum. The win moves the Cyclones to 8-7 in the Big 12 Conference, 17-9 overall. Missouri falls to 1-14 in the Big 12 and 11-15 overall.

Christine Flores led Missouri with 16 points. Iowa State trailed for nearly 37 minutes of the game, taking a 56-54 lead on a pair of Chassidy Cole free throws with 45 seconds left in regulation. Missouri’s Sydney Crafton hit a three  with 3.4 seconds left in the second half that forced overtime.
