Five takeaways and a 38-17 win over the Raiders improved the 49ers to 7-1 on Sunday, according to NBC Sports.
San Francisco bounced back strongly after a stumble just before their bye week.
The 49ers controlled the first half by putting together three touchdown drives of at least 12 plays. That sustained pressure built a 21-10 advantage by halftime.
That lead stretched immediately on the first play of the second half. Linebacker Jaden Dugger intercepted Cousins for a pick-six, pushing the score to 28-10.
Las Vegas responded with a touchdown when Brock Bowers caught a 21-yard pass, but the team’s momentum stalled from there. Fumbles by Michael Mayer and Bowers kept the offense off the board in the third quarter.
According to NBC Sports, the Raiders recorded a giveaway on each of their final four possessions. They finished the contest with turnovers on five of their last six drives.
Brock Purdy completed 17 of 25 passes for 232 yards, throwing two touchdowns and one interception. He also added 40 rushing yards on seven attempts before Mac Jones entered for mop-up duty late in the fourth quarter.
Cousins finished 22 of 32 for 216 yards, throwing one touchdown and three interceptions. Bowers led the Raiders with seven receptions for 111 yards and a touchdown.
Meanwhile, the Las Vegas run game stayed a non-factor. Ashton Jeanty managed just 25 yards on six carries.
The loss extends a tough stretch for Las Vegas, which has now dropped five of its last six games. The Raiders head back home next Sunday to face the Seahawks.
San Francisco hits the road for Week 10. The 49ers will travel to face the Cowboys.
