Brooke Griffin had four goals and an assist for the Terrapins (18-3). Maryland will face the winner of Northwestern-Duke game, which was scheduled for Saturday night.
The Terrapins trailed 5-3 before going on a five-goal run in which Schwarzmann contributed a goal and two assists. The Terrapins led 9-6 at halftime, then let the margin slip to one goal before pulling away.
Brittany Dipper had eight saves, and four different players contributed two goals to the Maryland attack.
Hannah Schmitt scored five goals for sixth-seeded Loyola (14-5). The Greyhounds are coached by Maryland graduate Jen Adams.
Maryland’s defense held Greyhound star Marlee Paton without a goal for the first time in 26 consecutive games. With four goals Saturday, Schwarzmann moved up to No. 8 all-time on Maryland’s single season goals list with 69.
“First I’d like to congratulate Loyola on a phenomenal season,” head coach Cathy Reese said. “Obviously Jen (Adams) and Dana (Dobbie) are two Maryland alums and two of our best friends so this was a game that we knew was going to come down at some point. I’m just proud of them and the job they have done at Loyola and the season they have had.
“For us here we are, where we want to be, heading to the final four so this is a moment that we are enjoying. This has been a really fun team this season. We started out the year and they didn’t realize how good they were. We played five freshmen most of the game on this team today.”
