In the two extra frames, Drake had the best looks, taking five shots to ISU's one. Haig made five saves in the overtime periods to preserve the tie. The six shots on goal in the game for Iowa State was its lowest output since its winning streak began after a 1-0 loss to Indiana on Sept. 4.
The second half proved to be a defensive struggle as both teams could only muster five shots combined. ISU got on the board first in the 59th minute as Drake, attempting to clear the ball out of their own box, put the ball in the Cyclones' goal.
The Bulldogs evened the score at one apiece shortly after as Kristin Underwood scored her second goal of the season off a cross. Danielle Oswald and Bailey Wilberts were credited with the double assist on the play for Drake.
ISU's leading scorer, Renee de St. Aubin was held in check most of the night, as Drake did not allow her a shot on goal. De St. Aubin came into the game with goals in four-consecutive outings. Senior Amy Flores led Iowa State with three of its six shots.
Up next for the Cyclones is its Big 12 Conference opener at Texas Tech on Friday.
