GREENSBORO, N.C. — Maryland is peaking at the perfect time.

John Gilchrist made one of two free throws with 3.7 seconds to play to help the Terrapins win their third consecutive game. They defeated No. 15 Wake Forest, 87-86, in the quarterfinals of the ACC tournament.

With the game tied at 86 with 12.9 seconds to go, Gilchrist took the inbound pass and was deliberate in looking for his shot. But he was fouled by Taron Downey as he drove toward the basket.

He made his first free throw. Wake Forest called timeout, and Gilchrist purposely missed the second shot. The Demon Deacons scrambled for the rebound before Downey lofted up a last-second shot that did not come close.

Maryland advanced to play second-seeded North Carolina State in Saturday's semifinal. It will be a rematch of the Terps' 70-69 victory March 3.
