RICHMOND, Va. -- A pair of overtime draw controls led to a pair of UMass goals including Tanner Guarino's game-winner in the second half of the extra period giving the No. 15 Minutewomen a 15-14 victory at Richmond on Friday in the Atlantic 10 opener for both teams. In the first half of OT, Guarino won the draw control allowing UMass to set up a goal by Jesse O'Donnell. The Minutewomen again won the draw control to start the second half of OT where Guarino's tally served as the decisive goal.

UMass improves to 10-1 overall and 1-0 in the Atlantic 10, while Richmond falls to 4-6 overall and 0-1 in league play. 

The Minutewomen led by two goals late in the second half before the Spiders were able to tie the game thanks to a pair of Sam Stevenson tallies. With 6:04 to go, Stevenson brought the Spiders within a goal, while her fifth goal of the day tied the game with 38 seconds left in regulation.

After Richmond won the ensuing draw control, UMass took possession off a turnover with 15 seconds to go calling timeout. The Minutewomen were unable to get off a shot forcing the overtime period.

In the second half of overtime, Danielle Pelletier controlled the draw allowing UMass to take a timeout and again hold possession. Guarino rung up the game-winner with 21 seconds remaining. Richmond again won the ensuing draw control, but Houlis picked up a groundball of a Spider turnover with two seconds to go allowing UMass to hold on for the win.

The game featured six ties and UMass unable to take more than a three-goal lead during the game.
