NEWTON, Mass. -- Sophomore Mikaela Rix scored a game-high four goals as Boston College beat its second top-10 opponent in as many games, defeating No. 6 Duke 10-9 at the Newton Campus Lacrosse Field on Saturday.

The Eagles (6-6, 3-2 ACC) beat the Blue Devils for the first time in program history and set a program-high for ACC wins in a season.

"I'm just so happy for my girls - they worked so hard. We had a hard week. We've had a lot of ups and downs, and so to be honest I'm just so proud of the girls," head coach Acacia Walker said. "They're young, they stepped up and we won a close game. Duke is an excellent team, and we're excited about the win."

BC held Duke to its lowest scoring output of the season since the Blue Devils managed six goals against Maryland on Feb. 24. The Eagles maintained a lead of no larger than two throughout the second half.

"That's a sign of maturity, and we have a really young team so I give all the credit to the leaders on the field," Walker said. "Alex Frank and Jen Kent, my assistants, have done a ridiculous job with our defense so I'm so proud. The whole year everyone has been saying that defense is going to be our weak spot, and Jen and Alex have done a great job with them."

Freshman Sarah Mannelly scored three goals including two in the second half and sophomore Covie Stanwick recorded two goals. Junior Kate McCarthy scored once and classmate Cali Ceglarski tallied an assist.

After the Blue Devils jumped out to a 3-0 lead inside of the first five minutes, Rix scored BC's first goal of the game more than 12 minutes into the contest. Duke followed with a goal to push its lead to 4-1.

The Eagles answered with a 4-0 run during a five-minute span to capture a 5-4 lead with 10:09 to play in the first half. McCarthy started the run as she charged into the arc and found the back of the net before Rix scored her second goal of the game off a free-position shot. Stanwick and Rix scored BC's next two goals to close the run.

Duke tied the game with a goal before Rix scored again off a free-position shot to give the Eagles a lead they did not relinquish. Mannelly scored her first goal of the game with two minutes left in the first to give BC a 7-5 halftime advantage.

The Blue Devils scored two of the second half's first three goals to pull within 8-7 with just under 20 minutes to play before Stanwick connected on a shot off a Ceglarski pass to push BC's lead to 9-7 with 18:29 remaining.

Duke pulled within one goal on two occasions in the last 15 minutes, but the Eagles were able to fight off the visitors' comeback attempt. A Mannelly goal off a free-position shot with 8:13 to play gave the Eagles a 10-8 lead. After Duke scored with 3:44 to go, BC held the Blue Devils scoreless for the duration of the game.
