The Fighting Scots had the Pioneers on the ropes most of the way. Laura Jahn had six points as Monmouth finished the first half with a 10-2 run to lead 35-25. The hosts fought off an early Carroll surge to start the second half and were able to get the margin back around 10 for an extended period.
The lead was still seven with just over a minute to go when Carroll's Crystal Hoewisch took over. The conference's second-leading scorer had been held under wraps by Melissa Gorski, but she made an old-fashioned three-point play with 1:11 left and two free throws at the 0:38 mark to cut the margin to two. Gorski, Monmouth's leading free throw shooter, was 1-of-2 at the line with 26 seconds left, and Hoewisch drained a tough trey at the 10-second mark to tie the game at 69-69.
Ashley Yeast missed a shot in the lane before the buzzer, and Carroll then controlled the overtime, scoring on three straight second-chance opportunities at the outset.
Carroll's Kim Wickert had eight of her game-high 26 points in the extra session and Hoewisch finished with 18.
For the Scots, who fell to 10-10 on the year and 4-9 in the MWC, Jahn scored 24 and Yeast added 18 points, 15 rebounds, four steals and three assists. Gorski, who played all 45 minutes, had 19 points and 10 assists.
