The Terps did not register a shot on goal.
The No. 4-seed Terps will face the No. 5-seed Iowa Hawkeyes on Wednesday for a spot in the semifinals.
The Terps snapped a three-game losing streak and entered the Big Ten tournament on a high note.
The goal lifted the Terps to a weekend sweep of the Scarlet Knights.
All four Maryland goals resulted from penalty corners.
Scarlet Knights' coach Meredith Civico was one of the pieces to Maryland's 2005 national championship-winning side.
The Terps tallied 13 shots but were shutout Sunday.
Wolverines goalkeeper Anna Spieker made five saves.
The Terps had been tough to break down, conceding few chances in matchups against the Big Ten's best teams.
The goalkeeper pitched a shutout in the Terps' win over the No. 2 Hawkeyes on Friday.
