There were no burned out cars in Kansas City this morning ... in fact, it's been a regular sleepy Monday with cops telling TMZ Sports the city was VERY well behaved after the World Series last night.

A rep for the KC Police Department tell us there were ZERO World Series-related arrests after the Royals won the crown ... a HUGE difference from the scene in San Francisco one year ago.

As we previously reported, SF was a war zone when the Giants won in 2014 -- with 40 total arrests, 9 police cars damaged, 3 officers injured and 2 people shot.

But Sgt. Darin Snapp tells us in K.C., "It was a great night."

"There were no fights, no damage, no arrests in relation to the celebration. Everyone had a good time. A successful night for the Royals and the community of Kansas City Missouri."
