The Cavaliers were cold from the onset.
They opened the game 2 of 10 from the field, but started to turn things around when Atkins rejected Alvin Ellis III's attempt at a one-handed dunk, leading to a corner 3-pointer from Ottawa's Marial Shayok at the other end.

Virginia cut the lead to two to start the second half behind two quick baskets by Justin Anderson. The Spartans countered with a 12-2 run led by Dawson, who had seven points during the stretch, including a three-point play off a fastbreak dunk.
Down six points, Atkins picked up his fourth foul with 8:36 left on what replays showed to be a clean block on Gavin Schilling and was forced to go to the bench.
Virginia got within five after Atkins returned to the lineup before Trice knocked down a clutch 28-footer with 1 second left on the shot clock to put the Spartans up 52-44 with 3 minutes to play.
Virginia finished with its second straight 30-win season, a school record.
