There are no more undefeated women's basketball teams in the top 20. Third-ranked Maryland lost yesterday to 20th-ranked North Carolina State, 76-71, in an Atlantic Coast Conference game at Cole Field House.

The Terrapins, undefeated in 16 games, were ahead, 36-35, at the half despite shooting only 37 percent because Debbie Lytle had 12 points.

The lead changed back and forth early in the second half before the Wolfpack went ahead for good, 55-53, on Linda Page's 20-footer with 10:10 to play. Four and a half minutes later, N.C. State's margin was 63-58. Page and guards Angie Armstrong and Robyn Mayo kept the Wolfpack (14-4) in front the rest of the way as it tied the Terrapins for the conference lead at 6-1.

"It's our biggest road win ever," Coach Kay Yow said. "The players did an outstanding job of executing our game plan. Before . . . we hadn't put two good halves together. We played with more patience and poise on offense, but still our defense was our strongest suit."

That tough defense helped force the Terrapins' Jasmina Perazic to miss 12 of 19 shots and freshman Chequita Wood to miss 10 of 14. As a team, the Terrapins made only 31 of 71 (.437) as they lost at Cole for the first time in 12 games.

"It was about time," Maryland Coach Chris Weller said. "I could feel it coming the last week. We were overconfident. We lost a little fire. It wasn't the pressure of being undefeated, it was just coming too easy . . . We were very lethargic out there; we need these kind of games."

The Wolfpack made 34 of 65 shots, 19 of 32 in the second half. Page, the ACC's top scorer, had 16 of her 26 points that half, mostly from long range against the zone.

According to Weller, "You knew we were in trouble when the coaches couldn't recognize what defense we were in. I didn't feel good at all during the game. We weren't attentive to detail. It was our worst shooting game. Their defense was all over us. We probably should have gone to the box and one on Page sooner. N.C. State was just a better team.''
