A costly turnover in the final minute likely cost the Stanford men's basketball team a first-round bye in the upcoming Pac-12 Conference tournament.
Oregon made three free throws in the final 14 seconds to edge the host Cardinal, 73-70, Sunday in a conference contest in Maples Pavilion.
Chasson Randle led Stanford (9-7 Pac-12, 18-10 overall) with 17 points, but could not draw a foul with the game tied at 70 in the final 20 seconds on a drive to the basket.
"I was attacking, going to the basket," Randle said. "I tried to create contact but I guess it wasn't enough."
Stanford fell into a fifth place, a half-game behind UCLA (10-7, 18-12) with two games remaining. The Bruins hold the tie-breaker over the Cardinal because of their series sweep.
The Cardinal plays at Arizona State on Thursday night and at Arizona on Saturday. The Bruins, who defeated Washington State on Sunday (72-67), finish their season with a game against USC on Wednesday.
Stanford needs to sweep the Arizona schools and have UCLA lose to USC to move ahead of the Bruins.
"We have to focus," Stanford coach Johnny Dawkins said. "We go on the road against two good teams. We still have opportunities."
Stefan Nastic, who made two foul shots with just over a minute left to tie the game, had 16 points. Marcus Allen netted 14 points and grabbed a team-high seven rebounds.
Anthony Brown, who scored 11, hit a layup and short jumper to give the Cardinal a 62-59 advantage with just under six minutes to play in a game that featured 15 lead changes and was tied 11 times.
The Cardinal had to recover from an eight-minutes stretch in the first half when Oregon took a six-point lead into the intermission.
Stanford held the lead for most of the early going, but then went cold, missing its last seven shots of the half.
The Cardinal did come all the way back, taking a 47-44 lead with 13:44 remaining to play. Nastic hit a putback and the ensuing free throw.
Neither team led by more than eight points during the game.
"It's disappointing for the seniors," Dawkins said. "They've all had terrific careers here and they did some amazing things."
