Stevenson, which entered the game ranked 20th in the country in this week's IWLCA Division IIII National Poll, improves to 5-2. Springfield evens its record at 1-1.
Dobson led all Springfield scorers with six points, while Allie Davis, Kelly Gallo, and Nicole Soucie each tallied a pair of goals. Jackie Moscardelli added a pair of assists as well for Springfield.
The Mustangs led 8-4 at the half and 10-6 midway through the second before the Pride rallied to tie the game at 10-10. With less than a minute remaining, Springfield had possession looking for the game-winning goal.
However, a double team caused a turnover and gave Stevenson possession with 20 seconds left in the second half.
With under 10 seconds to play, freshman Mandy Marston fed the ball inside to junior Emily Gartrell who was triple teammed, but managed a flip pass to Megan Weiss on the crease for the game-winning strike with just three seconds left on the clock.
The Pride will look to pick up a win in on Thursday when it battles Claremont Mudd-Scripps.
