USC got back to its winning ways this past weekend with a 45-37 victory over Arizona.

The Trojans were missing several key starters and facing one of the Pac-12’s most entertaining offenses at Arizona, but managed to pick up a win that coach Lincoln Riley said made him proudest of any this season.

The show returns to the L.A. Coliseum next Saturday with no signs of slowing down. USC hosts a Cal team that has lost four straight games.

So it should come as no surprise the Trojans have opened as an 18-point favorite in the game, according to Circa Sports. The over/under is set at 58.5.

USC is 5-3 against the spread this year. The over has hit in five games. One thing to note: USC has been favored by at least 14 points three other times this season.

It covered a 31.5-point spread in the opener against Rice. The Arizona State game featured a 24.5-point spread and a 17-point win. The Arizona game this past weekend featured a 14-point line and a seven-point win.

Riley will take the wins, though.

Kickoff is set for 7:30 p.m. PT on ESPN.
