No. 12 USC women’s lacrosse made a statement Friday in its victory against No. 16 Boston College by doubling the Eagles’ score. The 18-9 win marks USC’s first win over BC in series history. The Trojans were previously 0-5 against the Eagles.

USC broke a 3-3 tie when graduate attacker Emily Concialdi intercepted sophomore goalie Rachel Hall’s clear attempt and immediately put the ball in the back of the net. From then on out, the Trojans never looked back.

Despite conceding the first goal of the game, the Trojans remained composed and kept with their game plan.

“I think we all know it’s a long game, so we’re trying not to focus on the score in the beginning and just kind of trust that after 60 minutes we’ll be happy with the result,” USC head coach Lindsey Munday said.

Concialdi's goal at the 13:33 mark in the first half sparked a 6-0 Trojan run in the span of five minutes, bringing the score to 11-5 by halftime. Concialdi scored four goals and had one assist on the day.

During this run, USC won all of the draw controls, giving them immense control over the game.

“Us winning some draws in a row really allowed us to build momentum and score and then reset,” said Munday.

The Trojans opened up the second-half scoring frenzy less than a minute into the frame on Concialdi’s third goal and senior attacker Hope Anhunt’s second of three, expanding their lead to 13-6 at the 23-minute mark.

Along with Concialdi and Anhunt, two more Trojans had hat tricks on the day — junior attacker Sophia Donovan and sophomore midfielder Katie Ramsey.

Munday commended her defense for continuing its remarkable play. USC allowed only two BC goals in the first 18 minutes of the second half, bringing the score to 15-7 with 11:58 left in the game.

“Our defense all year has really done a great job of making adjustments after a goal is scored and locking in the next set,” Munday said. “I mean, they held a great BC team to under 10 goals, so that’s really good stuff.”

Junior goalie Riley Hertford had another stellar game with 11 saves. She credits her defense for remaining locked in throughout the Trojans’ offensive run.

“As the game went on, we realized we weren’t playing a lot of defense sets so … we needed to make sure that when we did get a defensive set we were ready for the ball,” Hertford said. “[We needed to] make sure we were locked in and set because they were looking to push the ball right off the ground and run into the goal.”

USC also held BC standout attacker Charlotte North to 30% shooting on the day.

“She’s kind of the quarterback of their offense, so we definitely had our focus on her and where she was going,” Hertford said. “We knew that she’s a strong player. We played with her last year and the year before, so we figured that she was going to be looking to possess the ball a lot and look for those opportunities.”

After their impressive win, Munday said the Trojans are now focusing on their next game against San Diego State.

“This game is behind us,” Munday said. “The focus has been on us all, it’s not about who we’re playing. It’s just about us and getting better every single day.”

The Trojans host the Aztecs Sunday at noon at McAlister Field.
