COLLEGE PARK, Md. -- Dez Wells scored 23 points, Jon Graham scored 12 of his career-high 16 after halftime and No. 17 Maryland edged Penn State 64-58 Wednesday night to avert its first losing streak of the season.

The Terrapins (19-4, 7-3 Big Ten) were tied with 4:59 left before they pulled away from the Nittany Lions for their first win against Penn State as members of the Big Ten.

After building a 57-52 lead, Maryland let the margin dwindle to one point before Wells made two foul shots with 39.3 seconds remaining. Then, after a Penn State miss, Wells grabbed the rebound and added another free throw to clinch it.

Maryland improved to 4-0 this season following a defeat. The Terrapins were coming off an 80-56 loss at Ohio State.

“That was a good win and we beat a really good team," head coach Mark Turgeon, who turns 50 on Thursday, said. "I thought we were much better in the second half and Melo [Trimble] was great with the ball in his hands and he had a few key assists tonight. I thought we executed at a high level offensively during the last seven or eight minutes and we were really good defensively the last few minutes too. It was a good win and I am proud of our guys.”

D.J. Newbill scored 18 for Penn State (14-9, 2-8). The Nittany Lions are 0-6 on the road in the Big Ten, with five of those defeats by six points or fewer.

Graham, who played two seasons at Penn State before transferring to Maryland, scored a career high on six-for-seven shooting. Melo Trimble finished with a career-high eight assists.

Graham accounted for Maryland's first seven points after halftime to turn a 29-28 advantage into a 36-31 lead. Two of his baskets came on passes from Trimble, who had the Terrapins' lone assist in the first half.

A three-pointer by Wells upped the margin to eight points with 15:54 left.

Newbill then scored five straight points before Wells hammered home a dunk and added a free throw for a three-point play. But Newbill answered with another three, and a basket by Shep Garner made it 42-41.

The Terrapins remained in front until Devin Foster made a layup with 9:48 left to make it 47-46, Penn State's first lead since 28-27.
