With less than 30 seconds remaining, Penn’s Catherine Berkery swung a pass to Keeley Block inside the eight-meter arc.

Maryland women’s lacrosse top ranked defense has typically prevented those shots from turning into goals this season. But that wasn’t the case on Monday. Block rifled the game-winning shot into the net.

The loss marks the first time No. 8 Maryland women’s lacrosse has lost consecutive games to No. 15 Penn, falling 13-12 at Franklin Field. The loss dropped the Terps record to 2-3 against ranked opponents.

“In the middle of the game, we just had some lapses,” coach Cathy Reese said. “Too many turnovers, too many missed shots.”

The Terps (7-3, 3-1 Big Ten) committed a season-low three turnovers in their win over Oregon on Thursday. But Penn’s No. 21 ranked scoring defense was a different challenge. Maryland committed five turnovers within the contest’s first 16 minutes.

The Quakers’ (6-3, 2-0 Ivy League) defense intercepted three passes in that stretch. Turnovers have been a reason for concern this season, but Maryland’s limited the issue in recent weeks, committing the third fewest turnovers per game mark in the Big Ten.

It regressed back to its early-season struggles against Penn, committing 13 turnovers.

Even when Maryland’s offense generated a shot on goal, Penn goalkeeper Orly Sedransk thwarted the Terps’ attack. The freshman was one of Inside Lacrosse’s top freshmen, ranking as the first among incoming goalkeepers.

Sedransk entered the contest with a .429 save rate and carried her stellar play into Monday’s contest, posting six saves on 11 Maryland first-half shots on goal.

But Maryland’s goalkeeping struggled to keep pace with Sedransk.

Senior midfielder Anna Brandt scored four times on Monday, akin to last year’s contest, and her final goal forced a goaltending change.

“We just felt like they were hitting a lot of shots and opportunities,” Reese said. “I think to come in and make some of the stops she made, that’s pretty tough.”

Terps’ goalie JJ Suriano surrendered 11 goals on 16 shots, with multiple goals coming from the edge of the eight-meter arc.

Reese subbed in backup goalie Julia Ward with 13 minutes remaining. While the freshman was better, making three saves on five shots on goal, the Terps could not mount a comeback.

One of the few bright spots on Maryland’s offense was midfielder Kori Edmondson. The junior scored twice last season against Penn and matched that in the first half, converting on fast break chances.

Edmondson finished the game with four goals, with three via transition offense.

Immediately following Brandt’s final goal, Edmondson grabbed the draw control and took off. She weaved her way through a pair of defenders before completing her seventh hat trick this season.

The junior had one of her best games of the season, but the Terps’ defense failed to contain Penn.

Maryland defender Kennedy Major missed the game due to an illness. The junior entered the year on Inside Lacrosse’s Preseason Second Team All-American list, and her presence was missed early in the matchup.

“She’s a captain … a leader for us on defense,” Reese said. “When you lose that experience … against a team with a lot of really good attackers, they put up a lot of good numbers.”

The Quakers scored on their first two possessions and continued to strike throughout the first half, shooting 61.5 percent.

While the Terps’ defense was better in the second half, it failed to make a stop on the most important possession of the game.

The Terps’ woes against ranked opponents are concerning as four of its final six games of the season come against a top-25 ranked team.
