Second-seeded Nansemond River dominated No. 7 Grassfield for one quarter on Tuesday night in a quarterfinal game of the Southeastern District girls basketball Tournament. The Lady Warriors routed Grassfield 21-6 in the second period to take a 30-15 halftime lead. The eight-minute stretch was enough as NR advanced with a 58-40 victory.

Nansemond River head coach started none of his usual starting five, instead having substitutes Kiara Washington, Sloane Smith, Briana McClain, Ciera Mobley and Tierra Armstrong start.

Grassfield couldn’t take advantage as the Lady Warrior reserves played physical, full-court defense and forced 14 turnovers in the first period. The result of a frantic first period was a 9-9 tie.

NR’s first string started the second period. Two straight baskets by DeShanna Honore’, a coast-to-coast drive after grabbing a rebound on the defensive end of the court, then a hoop inside off a pass from Trinese Fox, put NR up 19-10. Andrea Jones, who finished with a team-high 15 points, canned two three-pointers in the last 1:20 of the half to take NR’s lead into double digits.

Jones added seven points in the early stages of the second half and the Lady Warrior lead remained comfortable the rest of the way. Fox scored six points in the second half and Armstrong added five points.

NR continued forcing Grassfield into plenty of mistakes as the Lady Grizzlies wound up committing 30 turnovers. Some of Grassfield’s problems were unforced though. NR’s physical defense led to plenty of fouls on the Lady Warriors, but Grassfield wasted chances at the foul line, shooting 40.5 percent (15 of 37). NR managed only 42.4 percent (14 of 33) at the line.

Jones, along with her 15 points, had seven rebounds and three steals. Fox had nine points and seven assists. Armstrong had seven points and eight rebounds.

Nansemond River (19-4) has won 13 of its last 14 games with two of the 13 wins coming by single-digit margins. The Lady Warriors face King’s Fork on Thursday at King’s Fork in the tournament semifinals.
