One week ago Sean Sutton's Cowboys ended their two-year road losing streak.
Winners of 3 of their last 4, OSU was looking to make a major statement today as Bill Self's Kansas Jayhawks visited Stillwater.
With a final score of 61-60, OSU handed Kansas only its 3rd loss of the season.
The Cowboys have now won four out of five and improve to 5-7 in the Big 12.
Eaton holds a career high 26 points including the game-winning free throw.
Next up: at Missouri on Tuesday night.
