Quick look at Week 4 Pac-12 games

The Pac-12 slate is beginning in earnest this week, though Stanford and Washington are off.

Here's a quick look at Week 4 in the conference. All times are ET.

Oregon State (1-0) at No. 19 UCLA (3-0) 3:30 p.m., ABC/ESPN2: UCLA leads the series 40-15-4, including a 27-19 win last year in Corvallis. With his 13th career 100-yard rushing day in the win over Houston, senior RB Johnathan Franklin moved into second on UCLA's all-time rushing list with 3,210 yards for his career. Oregon State has played just one game. Every other Pac-12 team has played three. UCLA ranks second in the nation in total offense (622 yards per game) and fifth in rushing offense (311 yards per game). Oregon State, based on its win over Wisconsin, is ranked second in rushing defense (35 ypg) and fifth in total defense (207 ypg).

Colorado (0-3) at Washington State (2-1) 4 p.m., FX: Colorado leads the series 4-3, but Washington State won a 31-27 thriller in Boulder last year. The Buffaloes led 27-17 with just over five minutes left, but a 63-yard TD pass from Marshall Lobbestael to Marquess Wilson with 1:10 remaining provided the winning margin. The Cougs iced the game when the Buffs fumbled in Washington State territory on the ensuing possession.

California (1-2) at No. 13 USC (2-1, 0-1) 6 p.m., Pac-12 Network: This is the 100th meeting between the schools. USC leads the series 64-30-5, although the Trojans' 2005 victory was later vacated due to NCAA penalty. The Trojans have won the past eight meetings, with the Bears averaging just 10.3 points in those games. In fact, USC has won 10 of 11. The the lone loss came in 2003, 34-31 in triple-overtime, and the Trojans went on to win the national title that year. USC holds a 31-18-4 edge in the Coliseum.

Utah (2-1) at Arizona State (2-1) 7 p.m., Pac-12 Network: Arizona State is 17-6 against Utah and has won eight in a row in the series, including the past six games in Tempe. The first game since 1993, however, was last year's 35-14 Sun Devils victory in Salt Lake City. The two schools were conference rivals in the WAC from 1962 to 1977 until ASU joined the Pac-10 in 1978.

No. 22 Arizona (3-0) at No. 3 Oregon (3-0) 10:30 p.m., ESPN: A matchup of two of the most celebrated architects of the no-huddle, spread-option offense. Oregon leads the series 23-14 and it won 56-31 at Arizona last year. Both teams rank in the nation's top 7 in total offense. Arizona is fourth with 604.7 yards per game and Oregon is seventh with 596.3 yards per game.
