COLLEGE PARK, Md. --  Maryland will move on to the NCAA second round Sunday, as it held off Iowa 4-2 in NCAA first-round action. Senior Jemma Buckley scored twice and redshirt senior goalkeeper Melissa Vassalotti registered four key saves in the second half to preserve the win.

"Maryland put together 70 minutes of very strong, intense hockey," head coach Missy Meharg said. "It was a demonstration of what we have been looking for, and it couldn't have come at a better time."

Buckley, the Terrapins' leading scorer, notched her 19th and 20th goals of the season in the first half. In the fifth minute of play, she drilled in a shot off of a corner set up by freshman Katie Gerzabek and junior Harriet Tibble.

Iowa's Kim Scraper knotted the game at one when Sarah Drake found her up ahead near the goal for the tip-in score in the 17th minute.

The Terrapins won a penalty corner in the final seconds of the first period. With time expired, Buckley sent in her second goal of the day, off the same set up as her first, to give Maryland a 2-1 lead at the break.

Junior Megan Frazer made it 3-1 Terps in the 44th minute. Junior Janessa Pope found her on the left side and Frazer flicked in the goal for the score.

Iowa called a timeout when Frazer scored, then Scraper added the Hawkeyes' second goal just two minutes later.

Redshirt freshman Shelby Sydnor extended Maryland's lead to 4-2 when she tipped in a loose ball after a rebounded shot with 19:23 left to play in the game.

The Terrapins outshot the Hawkeyes, 22-10, for the game and had eight corners to their three.

Vassalotti ended with four saves and Iowa goalkeeper Kathleen McGraw had 12.
