Defending Class 1A state champion and No. 4 Dunbar continued its march to the state finals at UMBC's RAC Arena on Wednesday.
Michelle Wright scored a game-high 17 points and the host Poets beat Northwestern, 57-27, in a Class 1A South regional semifinal.
The Poets (16-6) will face the winner of Ben Franklin-Masonville's game with Surrattsville in Saturday's regional final.
