The nation noticed the Pac-12's big weekend.

After posting three victories over ranked teams, five Pac-12 teams are ranked and two others received votes in the AP poll.

USC is still No. 2 behind Alabama. It received eight first-place votes behind 48 for the Crimson Tide. Oregon remains No. 4.

Stanford is 21st, UCLA is 22nd, Arizona is 24th.

As for receiving votes, Oregon State is 29th and Arizona State is 38th.

Oregon State beat No. 13 Wisconsin, UCLA beat No. 16 Nebraska and Arizona beat No. 18 Oklahoma State.

Also, Stanford beat Duke, USC beat Syracuse and Arizona State beat Illinois, giving the Pac-12 a 9-3 record for the weekend and a 6-1 mark versus other AQ conferences. The Pac-12 was 3-0 against its Rose Bowl partner, the Big Ten.

Washington lost 41-3 at LSU. The Pac-12 gets a chance to post a win over the SEC when Arizona State visits new SEC member Missouri on Saturday.

On the downside, non-major conferences have been giving the Pac-12 trouble. The conference has lost to Independent BYU, Nevada and Colorado State of the Mountain West Conference and Utah State of the WAC. Also, Colorado lost Saturday to Sacramento State, an FCS team.
