ROHNERT PARK, Calif. - Playing under a light rain in Northern California, the 25th-ranked UC San Diego women's soccer team battled Sonoma State to a 0-0 draw Sunday.

Tritons' junior goalkeeper Kristin Armstrong tallied seven saves while keeping the hosts off the scoreboard. It marked Armstrong's ninth-career shutout.

UCSD stands at 3-2-1 overall and 1-2-1 in the California Collegiate Athletic Association. The Seawolves hold an overall mark of 1-2-2 while going 0-2-2 during league action.

The Tritons earned two corner kicks in the final five minutes of action Sunday but couldn't secure the game-winning score. Through the match, SSU took 16 shots to 12 for UCSD, a squad led by Sarah McTigue's four attempts and Hayley Johnson's three chances.

The Seawolves' offense tested the Tritons early, as SSU registered the first five shots of the match. Armstrong withstood the pressure, totaling five of her six saves in the opening half.

After the two squads entered halftime with the score 0-0, the Tritons' attack started to pick up its pace in the second period. UCSD earned five corner kicks in the final 45 minutes of regulation but none produced a score. The Tritons' best chance of the second half came at the 54:43 mark, when Mary McWalters lined a shot into the crossbar before the ball bounced away from danger.

The Seawolves continued to launch their own attempts, but the two teams failed to find a score through the first 90 minutes.

SSU collected the only shot on goal during the first overtime, an attempt from Taylor Edmonds that was stopped by Armstrong. UCSD controlled play during the second session of extra time, registering two shots and two corner kicks, but could not find the back of the net.

The Tritons will continue their CCAA road trip on Friday when they challenge Cal State Monterey Bay in Seaside, Calif., at 12:30 p.m. That contest will be followed by a 2 p.m. Sunday match at San Francisco State.
