COLLEGE PARK, Md. -- A stellar defensive effort vaulted top-seeded Maryland past Stony Brook 11-3 in the second round of the 2013 NCAA Women's Lacrosse Championship on Sunday.

Brooke Griffin led Maryland (20-0) with four goals while senior Tewaaraton finalist Alex Aust pitched in with four points on two goals and two assists.

Katie Schwarzmann -- who was recently named a Tewaaraton finalist for the third consecutive season -- put the Terps on the board and evened the score with a free position tally at 13:25, halting Maryland's longest scoring drought of the year. Beth Glaros then gave Maryland its first lead of the game with an assisted score from Kelly McPartland with 12:19 remaining in the first half.

Aust and Griffin pushed the lead to three with a pair of free-position goals with 5:40 and 4:02 left in the first half, respectively, as Maryland carried a 4-1 lead into the break.

Griffin and Taylor Cummings extended the Terps' lead to 6-1 with a pair of early goals in the second as Maryland began to settle into the match after a two-week layoff from the ACC tournament.

As the Terrapin offense continued to gain momentum, the defense was steadfast, not allowing a Stony Brook goal for 30 minutes to cap the first half and start the second. Demmianne Cook stopped the Seawolves' scoring lull six minutes into the second period, but the Terps wasted no time answering with a nice move by Kelly McPartland for a goal and a 7-2 advantage at 23:34.

Cook registered her 90th goal of the year with a free position score with 22:03 left in the contest. But again, Maryland answered, as Glaros netted her second score with a goal up the middle from a solid look from Cummings with 14:31 remaining to send Maryland's cushion back to five.

Three unanswered goals - including two from Griffin - gave the Terps a final 11-3 advantage for their nation-leading 52nd win in NCAA tournament play.

"I'd like to congratulate Stony Brook on an outstanding season. Today was a hard-fought game and I give them a lot of credit, I thought there defense really challenged us offensively," head coach Cathy Reese said. "I'm proud of our team effort today. We executed when we could and we were able to play very disciplined defensively and hold some of their big scorers."

Senior Iliana Sanza led the way for the backline with three caused turnovers and three ground balls as Maryland secured its eighth 20-win season with the victory and its fourth in the last five seasons.
