How to watch San Diego State vs. Washington State: TV channel, live stream

The San Diego State Aztecs will get a better measure of where they stand early in coach Sean Lewis’ second season when they travel to face future Pac-12 opponent Washington State at 7:15 p.m. Saturday at Martin Stadium in Pullman. The game will air on The CW and be streamed on the Mountain West Network.

Both teams are coming off home season-opening victories over FCS teams. San Diego State routed Stony Brook 42-0 while WSU struggled to beat Idaho 13-10 on a last-minute field goal in the Battle of the Palouse.

“We’ve got a really tough opportunity here to go on the road and see what we're made of, as we go into a hostile environment against a good Washington State team that found a way to win against a really good Idaho team,” Lewis said. “So, in a good place, you know, and like where we're at, and obviously, plenty of room to get better.”

What’s at stake

This game will be a chance for the Aztecs to get some payback and to gauge the level of competition they’ll face when they move to the new-look Pac-12 next season.

John Mateer rallied the Cougars from a 12-point deficit in the fourth quarter last year to win 29-26 at Snapdragon Stadium. Mateer and several other playmakers, as well as most of the coaching staff, bailed after the season, so this will be a whole different team the Aztecs will face.

Coach Jimmy Rogers was hired away from FCS power South Dakota State and brought two dozen players with him. Overall, the Cougars have 75 new players.

WSU leads the series 2-1. Next July 1, SDSU, Boise State, Utah State, Fresno State and Colorado State of the Mountain West will join Pac-12 holdovers WSU and Oregon State, along with Texas State in football and Gonzaga in basketball.
