Final score: Oregon 59, Cal 17
10:37 p.m. - Marcus Mariota throws his sixth touchdown pass, tying an Oregon school record, and this could get really ugly.
Oregon 52, Cal 17 with 11:43 left in the fourth quarter
10:23 p.m. - Marcus Mariota throws his fifth touchdown pass tonight, connecting with Colt Lyerla for his second score, and Memorial Stadium is quickly emptying out.
Oregon 45, Cal 17 with 14:29 left in the fourth quarter
9:56 p.m. - Just a brutal sequence for Cal as Allan Bridgford is picked off trying a screen on third-and-long, and Marcus Mariota hits Josh Huff for a 35-yard touchdown on the ensuing play.
Cal had been running the ball very effectively up the middle, but tried two passes and a run to the outside before the pick.
Oregon 31, Cal 17 with 6:20 left in the third quarter
9:43 p.m. - Isi Sofele and the Cal running game are just gashing the battered Oregon defensive line, with the redshirt senior now up to 118 yards on 13 carries, scoring on a four-yard touchdown.
The Bears are averaging 6.3 yards per carry.
Oregon 24, Cal 17 with 10:07 left in the third quarter
9:27 p.m. - The Cal defense player really well against the run in the first half, limiting Oregon to 65 yards on 20 carries, with running back Kenjon Barner managing just 25 on nine carries. But Marcus Mariota was 16-of-21 passing for 222 yards and two touchdowns to gives the Ducks the two-score edge.
Allan Bridgford was 7-of-12 for 87 yards and a touchdown, while Isi Sofele added 64 yards on eight carries.
Cal is 1-of-6 on third down, while Oregon is 3-of-7.
9:10 p.m. - Cal center Brian Schwenke was called for a hands to the face penalty that turned a third-and-one into a second-and-16. Vincenzo D'Amato missed the resulting 48-yard field goal, hooking left at the very last minute, and Oregon drove 69 yards for a Marcus Mariota to Josh Huff touchdown at the end of the quarter.
Oregon 24, Cal 10 at the end of the first half
8:51 p.m. Oregon quarterback Marcus Mariota was shaken up after landing hard on his shoulder at the end of a 16-yard scramble. Backup Bryan Bennett was sacked and threw two incomplete passes, and the Ducks settled for a 26-yard Alejandro Maldonado field goal.
Oregon 17, Cal 10 with 6:24 left in the second quarter
8:33 p..m. - Oregon scores on a short Byron Marshall run, but Vincenzo D'Amato comes back with a 27-yard field goal for Cal.

7:59 p.m. - Cal establishes the run on its second drive, setting up an easy Allan Bridgford to Darius Powe 10-yard touchdown, the first for each in their college career. If the Bears can keep Oregon off balance, they can hang around.
Oregon 7, Cal 7 with 8:04 left in the first quarter
7:46 p.m. - Marcus Mariota comes out throwing and picking on the Cal safeties, completing all four of his passes for 53 yards, including a 10-yard touchdown to tight end Colt Lyerla.
Oregon 7, Cal 0 with 10:41 left in the first quarter
7:30 p.m. - Oregon is really beat up on the defensive line, with former Cal recruit Arik Armstead going to start among other changes. If the Bears can establish the run early, they can make things interesting.
7:07 p.m. - Just back from a trip down to the field with a few injury updates...
Corner Marc Anthony (concussion) is good to go, but defensive lineman Viliami Moala is not dressed. I also saw Auburn (Calif.) Placer defensive lineman Eddie Vanderdoes, who is making an unofficial visit this evening.
Brandon Huffman has a full list of recruits scheduled to attend the game on the premium message board.
6:33 p.m. - No surprise, but redshirt senior quarterback Zach Maynard is not warming up with the other quarterbacks. It hasn't been officially confirmed, but all signs point to redshirt junior Allan Bridgford getting the start versus Oregon.
6:30 p.m. - Good evening from Memorial Stadium, for the night cap on what has already been a wildly compelling Shakeup Saturday, with top-ranked Alabama falling at home to Texas A&M.
