COLLEGE PARK, Md. (AP) -- Locked in another tight duel against an inspired foe, No. 4 Maryland turned to Marissa Coleman to turn things around.
Coleman came through, and the Terrapins survived an upset bid by Virginia to remain unbeaten at home.
Laura Harper had 25 points and 15 rebounds and Coleman fueled a second-half comeback that carried Maryland to an 86-80 victory Friday night.
Coleman scored 21 and grabbed 12 rebounds, Kristi Toliver had 16 points and 12 assists and Crystal Langhorne contributed 17 points on 8-for-10 shooting for the Terrapins (25-2, 9-1 ACC), now 17-0 at home.
Neither team led by more than three points until Toliver sank a 3-pointer to make it 49-44. Virginia's Paulisha Kellum then made two free throws, a follow-shot and a 3-pointer to ignite a 15-2 run that put the Cavaliers up 59-51 with 11:25 left. Lyndra Littles capped the surge with a layup and a shot from beyond the arc.
Coleman brought the Terrapins back, converting a pair of three-point plays and both ends of a 1-and-1 during a 13-2 spree that put Maryland ahead 64-61 with eight minutes to go.
"She really presents a challenge because of her size and skill level," Virginia coach Debbie Ryan said of Coleman. "She spearheaded the attack at that point, and we just didn't handle it very well."
Coleman's fist-pumping enthusiasm was nearly as important as her eight points in the pivotal run.
"She gave us a huge boost of energy right at a critical time," Terps coach Brenda Frese said. "She was aggressive, attacking to the rim, getting the three-point play. We needed to get a catalyst, and I thought she did a tremendous job."
Kellum scored 23 points, including 21 second-half points after a 1-for-10 shooting performance in the first half. Aisha Mohammed had 15 points for the Cavaliers before fouling out and Sharnee Zoll scored 13.
Virginia (17-5, 5-2) has lost only twice in its last 13 games, both times to the Terrapins.
"I feel like we played a very good game under very adverse conditions," Ryan said. "We were definitely on the losing end in the personal foul area. But we didn't let it bother us."
Maryland took 21 more free throws than the Cavaliers and outscored Virginia at the line 22-6.
After being forced into overtime in three of their previous four games, the Terrapins struggled before pulling away at Virginia.
"We're going to get everybody's best shot," Coleman said. "We're a great program and we've had some success the past couple years, so whenever we step on the floor we're going to get our opponent's best game."
Maryland led 66-65 before Coleman scored on a drive and Toliver drilled a 3-pointer to expand the margin to six. Kellum answered with a 3 and then followed two foul shots by Toliver with a three-point play to bring the Cavaliers to 73-71.
But Langhorne made Maryland's next three baskets, and two foul shots by Harper gave the Terrapins a 79-75 lead with 1:28 left. After a Virginia miss on the other end, Toliver made two free throws with 42.8 seconds remaining.
Maryland made the lead stand up in the final minute at the foul line.
A first half that featured nine ties and nine lead changes ended with the Terrapins up 37-36. Maryland shot 62 percent from the floor compared to 38 percent for Virginia, but the Cavaliers took 16 more shots, in part because the Terrapins committed 12 turnovers.
During the break, Maryland honored Shay Doron, a starter on the 2006 national championship team, by hanging her No. 22 from the rafters of the arena. She was the first player recruited by Frese.
