When the Virginia women's basketball team defeated Maryland in Charlottesville, Va., three weeks ago, the Cavaliers were unstoppable from the field, making 58 percent of their shots.

Last night at Cole Field House, sixth-ranked Virginia continued its hot shooting against 12th-ranked Maryland in the first half, making 57 percent of its shots.

But in the last 20 minutes, the Terrapins tightened up on defense, got strong inside performances from Christy Winters and Vicky Bullett and upset Virginia, 83-79, in an Atlantic Coast Conference game.

Maryland moved into first place in the ACC with a 7-1 record (15-4 overall). Virginia (6-1 and 17-2) had won 10 straight since its Christmas tournament loss to top-ranked Iowa.

"We weren't in the game defensively right from the beginning," Virginia Coach Debbie Ryan said. "We just didn't come out and play solid defense for 40 minutes. And when you don't, you can't expect to beat a team like Maryland."

Bullett scored 14 of her 20 points in the second half and was nine of 10 from the floor overall. Winters, a sophomore from South Lakes High School, had 12 of her 14 points after intermission.

Besides shooting 57 percent from the floor in the second half, the Terrapins played good defense. Virginia shot 39 percent in the second half and missed seven of its last eight shots when the game was on the line.

"We just felt we had to keep it in a controlled game," Maryland Coach Chris Weller said. "I think once we went into the 3-2 zone in the second half we did a better job stopping them."

Senior guard Daphne Hawkins from Beltsville and High Point High School led the Cavaliers with 24 points. Back court mate Donna Holt had 18, but only five the second half.

Maryland trailed by 42-36 at halftime, but stayed close and went ahead for good with less than four minutes left. With the Terrapins trailing by 76-75, Winters made two free throws, then converted a great pass from Deanna Tate to make it 79-76 at the 2:53 mark.

Virginia's Laurie Carter made it 79-78 with 2:33 left and Maryland's Edna Campbell made one free throw to give the Terrapins a two-point lead. But the Cavaliers missed seven of their next eight shots and Campbell and freshman Carla Holmes (11 points) made layups in the last 1:50.

Holmes' driving left-handed layup with 32 seconds left were the last points of the game.

In the first half, the Terrapins missed six of their first seven shots and trailed by 15-6. But they went on a 9-0 spurt that ended with Holmes' three-point shot that evened it at 15-15.

Late in the half, the Cavaliers used a big run to go back ahead. Down by 32-29, they scored 11 straight points to go ahead with 1:46 left in the half. Holt had nine points, including two three-pointers, and assisted on the other basket during the spurt.

But after halftime, Holt made two of nine shots from the field.

Virginia led by 42-36 at halftime, but Maryland went on a 14-6 run to go ahead, 50-48, on Tate's 12-footer from the base line. The Terrapins led by four at the 13:46 mark, but Holt made a three-pointer and Hawkins made two shots to put the Cavaliers on top by 59-56.

Later, after Tonya Cardoza's steal and layup, Virginia led by 73-68 with 6:43 remaining. However, Lisa Brown (15 points) scored four points, Hawkins and Bullett matched baskets, and the Terrapins were within 75-74.
