NORFOLK, Va. -- Nnemkadi Ogwumike scored 22 of her 28 points in the first half Saturday and top-seeded Stanford pulled away before halftime and beat Hampton 73-51 in the first round of the NCAA tournament.

Joslyn Tinkle added 16 points as the Cardinal (32-1) extended their school-record winning streak to 29. Stanford will face eighth-seeded West Virginia, a 68-55 winner against Texas in the early game at the Constant Center, on Monday night in the second round.

Alyssa Bennett scored 19 points to lead Hampton (26-5), which set a school record for victories in a season and was playing about 11 miles from its campus. The Pirates hadn’t seen anything like the athleticism of Ogwumike, or the efficiency of the Cardinal.

They got to see it all in the last seven minutes before halftime as Stanford took command.

With her almost equally dominant sister, Chiney, making trips to the locker room and riding a stationary bike after banging her knee early on, Ogwuimike scored eight points in a 13-0 run as Stanford extended its lead to 35-21.

Hampton scored the next five, keeping the partisan crowd hopeful, but Sarah Boothe hit a jumper. Ogwumike scored on a layup and then, with six seconds left in the half, made a high-arcing 3-pointer from the top of the key to give Stanford a 42-27 lead.

Chiney Ogwumike returned in the second half, and the Cardinal continued to pull away. Coach Tara VanDerveer kept her starters on the floor until late in the game, likely to work against the quickness of the Pirates and to get some game-speed work in.

Nicole Hamilton added 10 points for Hampton, which shot 32 percent compared to 58 percent for Stanford.

Hampton, which took Kentucky to overtime last year as a No. 13 seed before losing, has won the Mid-Eastern Athletic Conference title three years in a row since David Six became the coach, but is still seeking its first NCAA tournament victory.

The Cardinal are playing in their 25th consecutive tournament and seeking their fifth consecutive Final Four berth.
