The Pac-12 swings into action in Week 4 with nonconference play mostly done for the year. USC-Notre Dame, USC-BYU, and a few other nonconference games remain, but the first three weeks of the season have covered most of the nonconference slate.

Week 4 begins the Pac-12 Conference season in earnest with a full lineup of conference games on tap. Here are the TV times and networks for the six games between Pac-12 opponents.

All times are Pacific.

Washington State at Utah

11:30 a.m., Pac-12 Network

UCLA at Stanford 

3 p.m., Pac-12 Network

California at Washington

6:30 p.m., Pac-12 Network

Arizona at Oregon

7:30 p.m., ESPN

Oregon State at USC

7:30 p.m., Fox Sports 1

Colorado at Arizona State

7:30 p.m., ESPNU

It really is unfortunate UCLA-Stanford, a very interesting game between two teams with realistic chances of competing in their respective Pac-12 divisions, is being relegated to Pac-12 Network. Colorado-Arizona State is a game much more suited to Pac-12 Net this week.

The weather in Tempe is still very hot — close to 100 degrees this week — so a good change would have been to have Cal-Washington at 3 and Colorado-Arizona State at 7 with UCLA-Stanford getting a midday Fox Sports 1 slot.

Noteworthy: Fox Sports 1, at 12:30 p.m., has Colorado State-Iowa, a game in which Iowa is favored by 23 points.

That is on Fox Sports 1, while UCLA-Stanford is relegated to P-12 Net.

Yikes.
