WINSTON-SALEM, N.C. (AP) - Josh Adams scored on a 6-yard run on the first possession of overtime to help Wake Forest cap a stunning 21-point comeback and beat Maryland 31-24 on Saturday.

Alphonso Smith had a 100-yard interception return for a touchdown late in the third quarter to jumpstart the Demon Deacons (2-2, 1-1 Atlantic Coast Conference), who were trailing 24-3 before coming up with a rally almost as improbable as their run to last year's ACC championship.

Riley Skinner - playing in his first game since separating his shoulder in the opener - had a 1-yard TD sneak after Smith's return midway through the fourth, then found John Tereshinski with a 6-yard scoring pass to tie it with 3 seconds left in regulation.

Then, after Adams' score in overtime, the Demon Deacons closed the game with consecutive sacks. Jeremy Thompson took down Jordan Steffy on fourth down and forced a fumble, and Boo Robinson tackled offensive lineman Edwin Williams after he picked up the ball - a thrilling finish that sent the black-clad Demon Deacons spilling onto the field in celebration.

It was a stunning collapse for the Terrapins (2-2, 0-1), who got 112 yards and a touchdown from Keon Lattimore along with rushing scores from Lance Ball and Cory Jackson .

The win helped the Demon Deacons keep alive their chances of defending last year's league title, and a loss would have all but dashed those hopes with Boston College and Clemson remaining unbeaten in the Atlantic Division. Instead, it was Maryland heading home knowing it had let a sure win get away with shaky play down the stretch.

That was never more evident than on Steffy's third-down pass for Ball at the goalline with Maryland leading by 21 points and in search of the backbreaking score. Smith jumped in front of the route and raced the length of the field - weaving past Steffy and Danny Oquendo - to revive a listless crowd that had been shedding fans only minutes earlier.

Skinner completed 22 of 35 passes for 219 yards with three interceptions, but the redshirt sophomore came up huge down the stretch in directing the decisive scoring drives. Adams finished with 91 yards rushing.
