How it unfolded

The Browns drove into Levi's Stadium territory on the opening possession but settled for a Cleveland field goal. Garoppolo threw a touchdown to Marquise Goodwin to make it 7-3. Matt Breida broke an 83-yard touchdown run to push the lead to 14-3 late in the second quarter. The defense produced its first interception of Baker Mayfield. Robbie Gould kicked a field goal before halftime to make it 17-3. The third quarter was a Mostert touchdown drive. The fourth quarter was a Tevin Coleman touchdown. The 49ers' defense held Cleveland scoreless after the opening field goal.

The turning point

Matt Breida's 83-yard touchdown run in the second quarter. With the score still close at 14-3, Breida's burst through the gap on a stretch zone read effectively put the game out of reach and announced the 49ers' offensive identity in primetime.

Garoppolo 20-of-29 for 181 with a TD. Breida 11 carries for 114 including the 83-yard run. Coleman 11 for 26 with a TD. Bosa two sacks (now four in four games). Mayfield 8-of-22 for 100 with two INTs. OBJ 2 catches for 27.

Personnel watch

What it means

4-0 with the Rams on the road next week and Washington after that. The Monday-night dismantling of the Browns is the kind of signature primetime performance the year-three project needed. The defense, ranked second through four weeks, is the story.
