GENEVA, N.Y. -- No. 3 William Smith defeated No. 7 Ithaca 1-0 in an NCAA Division III Women's Soccer sectional championship match on Sunday played on Boswell Field, earning a spot in the national semifinals in San Antonio. The Herons (21-1-0) extended their win-streak to 21 matches and set a William Smith record for wins in a season.

The Herons also tied the program record for shutouts in a season, registering their 19th against the Bombers. William Smith earned its ninth appearance in the national semifinals after having the game delayed and moved to a new location due to snow.

Junior Dineo Mmutla drilled a hard shot from about 25 yards out into the back of the net to give the Herons a 1-0 advantage in the 65th minute. William Smith had earned a free kick moments earlier and the Bombers were trying to clear the ball out of the zone, but Mmutla was able to halt the clear, settle the ball and fire home her third goal this year.

Senior goalie Chelsea Dunay made five saves to earn her 16th shutout this year, which is a William Smith record for shutouts in a season. Dunay surpassed the mark set by Nikki Dudley in 2005. It was the Herons' 14th consecutive shutout.

The Bombers finished the year with a 19-3-0 overall record. Ithaca's best scoring chance came in the 40th minute. Anna Gray blasted a free kick on goal from about 30 yards out, but Dunay stepped up to make the save. Beth Coppolecchia played all 90 minutes in goal for Ithaca and finished with four saves.

Each team finished with 10 total shots. The Herons held a 6-2 advantage in corners.

William Smith will take on Capital (19-4-2) in a national semifinal match on Dec. 6.
