Javon Small scored 31 points to lead unranked West Virginia to an 86-78 overtime win over No. 3 Gonzaga in the quarterfinal round of the Battle 4 Atlantis on Wednesday.

The Bulldogs were favorites to win the preseason tournament and led 39-31 at halftime. But after Gonzaga took a 43-33 lead early in the second half, the Mountaineers went on a 10-0 run to tie the game, which was ended by a 3-pointer from Amani Hansberry. West Virginia continued the attack and took a 50-47 lead.

From then on, the game was back and forth. The Mountaineers took a 58-53 lead, but Gonzaga quickly answered with a 3 by Nolan Hickman. The Bulldogs appeared to take control of the game with a jump shot from Braden Huff with 1:52 left and took a 71-65 lead with 25 seconds left.

However, a 3-pointer from Tucker DeVries brought West Virginia up 71-69. DeVries wasn’t done from there, getting a steal and drawing a foul. He made two free throws to tie the game at 71-71 with five seconds left in regulation. Gonzaga ultimately couldn’t get a shot off, sending the game to overtime.

In overtime, West Virginia extended its lead at the foul line with Toby Okani and Hansberry each making two free throws to take a 77-73 lead. A layup by Small and two more free throws by Sencire Harris gave the Mountaineers an 81-75 lead with 1:04 left.

Harris essentially tied the game with a steal and dunk for an 81-76 lead. And two final free throws from DeVries gave West Virginia the winning score, 86-78.

DeVries scored 16 points for the Mountaineers, who improved to 4-1 with the win. Hansberry added 19 points and eight rebounds.

Huff scored 19 points to lead Gonzaga, followed by 16 from Khalif Battle and 13 from HIckman. Ryan Nembhard had 12 assists for the Bulldogs.

Gonzaga lost its first game of the season after defeating Baylor, Arizona State and San Diego State en route to a 5-0 start. The Bulldogs’ loss continued a difficult week for top-five teams, joining No. 2 UConn (losing to Memphis and Colorado) and No. 5 Iowa State (losing to No. 4 Auburn) in holiday tournament losses in the Preseason.
