STILLWATER, Okla. (AP) -- Le'Bryan Nash hit the winning fadeaway
jumper with 4.7 seconds left and blocked Chris Allen's attempt
for the tie at the buzzer to lift Oklahoma State to a 69-67
victory against Iowa State on Tuesday night.



The Cowboys (12-12, 5-6 Big 12) avenged perhaps their most
heartbreaking defeat of the season, having lost on Scott
Christopherson's banked-in 3-pointer at the buzzer in Ames.



After a game filled with back-and-forth runs, this one came down
to the final play too.



The Cyclones (17-7, 7-4) wiped away an eight-point deficit over
the final 5 minutes behind Allen's strong 3-point shooting, but
Nash connected to put OSU back ahead. Allen, who hit a
career-high six 3-pointers and scored 22 points, drove past the
arc and into the lane, but Nash swatted his shot into the stands
and preserve the win.



Markel Brown led Oklahoma State with 19 points. Nash finished
with 18.
