DES MOINES, Iowa – The whistle blew just in time for Oklahoma State.

Andrea Riley sank a free throw with 0.7 seconds left in overtime to give Oklahoma State a 73-72 victory over a gritty Florida State team Monday night in the second round of the New Orleans Regional.

The back-and-forth game appeared headed to a second overtime when Riley was trapped 18 feet from the basket with time about to run out. She went up for what would have been an awkward shot and official Teresa Dahlem whistled a foul on Florida State’s Shante Williams just as the buzzer sounded.

The officials then checked the TV monitor and put 0.7 seconds on the clock. Riley, who had missed two free throws on her previous trip to the line, bricked the first one but nailed the second, then intercepted Florida State’s long inbounds pass, allowing the Cowgirls to escape.
