Dalke, who played at the Masters tournament in Augusta, Ga. last month, holds a three-stroke lead entering Wednesday's final round.
Oklahoma is fourth in the team standings with a score of 557. It is 15 strokes behind first-place Baylor.
The Sooners are three strokes ahead of Brigham Young, Georgia Tech and North Florida. The top five teams and the highest individual after Wednesday's final round will advance to the NCAA Championship.
