Justin Graham converted a three-point play with three seconds left as visiting San Jose State remained unbeaten with a 75-72 win Saturday over Oregon.

The Spartans are 3-0 for the first time since 2001 thanks to Graham’s last-second heroics and the win was the first ever over a Pac-10 team since 1992. San Jose State’s Keith Shamburger and Adrian Oliver each scored 19 points, while forward Will Carter had 11 points and a team-high eight rebounds.

Oregon (3-1) was led by Joevan Catron, who tallied 25 points and nine rebounds. E.J. Singler and Teondre Williams each added 10 points for the Ducks.

San Jose State led for much of the first half before Garrett Sim made a 3-pointer to give the Ducks a 29-28 lead with 4:16 remaining. Oregon led at halftime for the first time this season, 39-34. The Ducks maintained their lead until 13:21 of the second half, when Oliver’s two free throws gave the Spartans a 49-48 lead. San Jose State then led until Catron tipped in a basket with four minutes remaining.

Catron followed his tip-in with a 3-pointer to give Oregon a 69-65 lead, capping a 14-4 run. San Jose State answered with its own 10-3 run to finish the game.

San Jose State, which was picked to finish sixth in the nine-team Western Athletic Conference, outrebounded the Ducks, 42-33.
