LOS ANGELES - Cal and USC clash for the 100th time Saturday afternoon at the venerable Memorial Coliseum.
7:55 p.m. - Final score: USC 27, Cal 9.
6:05 p.m. - Lee and Barkley hook up for their second touchdown of the afternoon, and this one is just about over.
I'm headed down to the field for post-game reaction. Back in a bit.
USC 27, Cal 9 with 5:56 left in the fourth quarter
5:53 p.m. - Cal held USC to 91 yards of offense in the third quarter, but is still allowing better than seven yards per play.
Maynard is 12-of-26 for 116 yards, no touchdowns and two interceptions.
5:44 p.m. - Andre Heidari hits a 41-yard field goal to give USC a two-score advantage.
It would be nice to see Brendan Bigelow gets some touches on this drive, but his inexperience with pass protections might be an issue. Whenever Sofele or Anderson are in, USC defensive end are going all out after Maynard.
USC 20, Cal 9 with 14:10 left in the fourth quarter
5:39 p.m. - USC is driving to end the third quarter, leading 17-9. Zach Maynard simply couldn't help himself, making an ill-advised throw in the red zone while scrambling that was picked off by safety T.J. McDonald.
5:16 p.m. - Memo to the Cal offensive brain trust: Bigelow running good, Maynard passing bad. The Bears settle for another D'Amato field goal.
USC 17, Cal 9 with 7:58 left in the third quarter
5:01 p.m. - Brendan Bigelow again sparks the Cal offense, but then two straight incomplete passes from Maynard force the Bears to settle for a short D'Amato field goal.
USC 17, Cal 6 with 11:56 left in the third quarter
4:53 p.m. - Looking at the first half stats, and it ain't pretty, folks. Cal has allowed 300 yards of total offense on 37 plays, while gaining just 98 yards on 34 plays. The ground game is especially glaring, with Isi Sofele and Anderson managing 30 yards on nine carries.
4:04 p.m. - Cal's defense was chipped to death by Nevada, and gutted by big plays at Ohio State. USC is doing both, scoring on an 11-yard pass from Barkley to Lee.
USC is well over 250 yards of offense in the first half. Thank goodness for Coleman's fourth-down stop and Williams' pick or this could be completely out of hand.
USC 14, Cal 3 with 7:01 left in the second quarter
3:56 p.m. - D'Amato hits a 24-yard field goal to put the Bears on the board. C.J. Anderson had freshman tight end Maximo Espitia wide open in the back of the end zone on a halfback pass, but overthrew him.
USC 7, Cal 3 with 10:15 left in the second quarter
3:42 p.m. - Somehow Cal is still alive and in this game, despite a disastrous performance from the Bears secondary as Marqise Lee drops an easy 72-yard touchdown after getting behind two defenders.
USC is moving the ball almost as will, while Cal's running game hasn't been able to get on track to keep Barkley and co. off the field
USC 7, Cal 0 at the end of the first quarter
3:36 p.m. After Deandre Coleman stuffs Redd on fourth down to give Cal the ball in USC territory, but Vincezno D'Amato misses another field goal, this time wide right from 35 yards.
3:22 p.m. Not sure if it says more about the importance of USC center Khaled Holmes or the state of Cal's defensive line, but the Bears are getting pushed around at the point of attack. Silas Redd scores on a 33-yard run.
USC 7, Cal 0 with 7:54 left in the first quarter
3:13 p.m. Steve Williams gets positioning on Robert Woods on a fade route in the end zone and intercepts Matt Barkley to snuff out a promising USC drive.
Safety Alex Logan whiffed badly on a long Curtis McNeal run that put the Trojans at the Cal 4-yard line. Don't be surprised if you see more from Michael Lowe in the defensive backfield as the game goes on.
2:58 p.m. - Robert Mullins announced as starter at inside linebacker over Nick Forbes.
Summers-Gavin and Rodgers are officially game-time decisions.
2:36 p.m. - Pre-game warmups are underway, and it looks like Summers-Gavin will return to the starting lineup for the Bears.
USC is also shuffling its offensive line, with Khaled Holmes (ankle) back at center and Abe Markowitz playing left guard.
1:59 p.m. - Cal will be without defensive end Keni Kaufusi, as the redshirt junior did not make the trip.
Right tackle Matt Summers-Gavin (knee) and tight end Richard Rodgers (foot) are game-time decisions.
1:22 p.m. - Good afternoon from a hot and hazy downtown Los Angeles for the Bears' conference opener
Both teams are coming off road losses, Cal falling at Ohio State by a 35-28 margin, while USC was ambushed 21-14 at Stanford.
