NEW ORLEANS - Once she had simmered down, LSU point guard Erica White sat in front of her locker and said she was embarrassed by the in-game shouting match she had with Oklahoma State star Andrea Riley.

LSU center Sylvia Fowles then half-jokingly accused the 5-foot-3 White of having something akin to a Napoleon complex.

"It's a little person's syndrome," the 6-6 Fowles said, chuckling. "Nobody can show her up without her wanting to do it better. ... That's what we love about her. She brings the fire. She brings the energy. That's what makes us a great team."

White scored 18 points and helped orchestrate a stifling defensive effort Saturday as the second-seeded Tigers took a 67-52 victory over the third-seeded Cowgirls in the regional semifinals of the NCAA Tournament.

LSU will face North Carolina in the regional finals on Monday night with a chance to go to a fifth straight Final Four.

Riley wound up draining six 3-pointers and finished with 26 points for Oklahoma State (27-8), but missed 19 of her 28 shots in the process.

RaShonta LeBlanc had 11 of her 13 points in the second half for LSU (30-5).
