Patterson received the 15th seed in the 3A North region and will travel to second-seeded Hereford in the first round on Friday, Feb. 24.
The Clippers (15-6) did not earn a top-four seed, which were determined by overall record, and went into a random draw for the fifth through 15th seeds.
The winner of Friday night’s game will advance to face the winner of seventh-seeded Towson and 10th-seeded Franklin.
Patterson advanced last year to the 4A state championship game, where it lost to North Point.
The Clippers also will play in the Division I City Championship game on Tuesday at Morgan State. Tickets are available only at the door.
