BERKELEY, Calif. -- No. 10 Oregon began the week on a nine-game winning streak and hoping for its first road sweep of the Pac-12's Bay Area schools since 1976.
That hope and the winning streak disappeared when the Ducks got blown out at Stanford on Wednesday, and the trip turned into a disaster when the Ducks blew an eight-point lead with less than seven minutes left in a 58-54 loss to Cal at Haas Pavilion on Saturday.
The Ducks (18-4, 7-2) lost to Cal for the 10th straight time. They committed 22 turnovers after turning ball over 20 times against Stanford, and they yielded 12 offensive rebounds to the Bears while getting just four off the offensive boards themselves.
The Ducks failed to score in the final four minutes of the game. After E.J. Singler missed a three-pointer with eight seconds left and the Bears leading by two, Oregon's Tony Woods was tied up on the rebound, giving Cal the ball.
Cal's Justin Cobbs hit two free throws with 3.9 seconds left to seal the upset.
Oregon again played without starting point guard Dominic Artis, who was sidelined with a foot injury.
Woods led Oregon with 14 points, and Arsalan Kazemi added 10. Singler scored just seven -- he was 1 for 6 on three-pointers -- and was shut out in the second half.
Richard Solomon had 13 points and 12 rebounds for Cal, and Allen Crabbe also scored 13 points. Tyrone Wallace had 12 as Cal won despite shooting just 35.6 percent from the field.
After trailing by three at halftime, Cal took a 42-39 lead with 11:28 left when Tyrone Wallace hit a three-pointer off a fast break that was initiated by Oregon's 17th turnover of the game.
Oregon then reeled off 11 straight points to surge ahead 50-42 at the 6:33 mark. The Ducks were aided by Cal turnovers on four consecutive possessions during the run.
Cal tied the game at 54-54 with 2:31 left on a Crabbe fast-break basket facilitated by the Ducks' 21st turnover of the game.
The Bears went ahead 56-54 on Cobbs' 17-foot shot at the 1:34 mark, and that was the final field goal of the game.
Oregon committed 11 first-half turnovers but still held a 27-24 lead at halftime.
The Bears helped out by shooting just 31.3 percent in the first 20 minutes.
Cal led 24-23 with 1:16 left in the half, but Woods hit four free throws in the final 1:03 to give the Ducks the three-point lead at intermission.
Woods' last two free throws of the half came as a substitute shooter for Johnathan Loyd, who injured his right hand or wrist and had to leave the game after being fouled by Brandon Smith with 16.4 seconds left in the half.
Loyd returned in the second half with his right wrist and thumb taped.
Singler, who went scoreless in the first half against Stanford, had seven first-half points, while David Kravish, Crabbe and Wallace had six first-half points apiece for the Bears. Crabbe's three first-half field goals came on fast-break layups as he failed to score out of the Bears' half-court offense.
NOTES: Artis missed his third consecutive game, and it's uncertain when he will return. Loyd again started in Artis' place, despite going scoreless in Wednesday's loss to Stanford. ... Cal's Allen Crabbe entered Saturday game as the Pac-12's leading scorer, averaging 19.8 points a game. ... Oregon entered the week hoping to sweep a road trip against the Pac-12's Bay Area schools for the first time since 1976. But Wednesday's loss at Stanford guaranteed that a Bay Area road sweep would elude the Ducks for the 37th consecutive season. ... Oregon took a charter flight home after Wednesday's game so players could attend classes Thursday and Friday. The Ducks returned to the Bay Area on Friday evening for the game against Cal.
