Some of the post-World Series win celebrated included bonfires.
The streets of San Francisco filled with exuberant Giants fans Sunday night following the team's sweep of the Detroit Tigers to clinch a World Series victory.
Some 10,000 people had already gathered at Civic Center Plaza outside City Hall to watch the game on a huge television screen. They erupted in cheers when the final out was made in the bottom of the 10th inning.
People who had been watching the game inside their homes or in City bars flooded outdoors. Sounds of car horns and fireworks were heard across the City in the moments after the win.
Fans also flocked to AT&T Park, Market Street and the Mission District.
Someone lit a large fire at the corner of 19th and Mission. Hundreds of people were seen crowded around the fire which burned for at least two hours. Police did not seem to put any effort into putting it out initally, but later in the night police in riot gear arrived to put an end to the party.
Thousands of fans also made their way to the streets surrounding AT&T Park, where more small bonfires also burned.
There were other fans seen on top of Muni buses and other cars along Market Street. A KGO reporter Tweeted a photo of a car on its side on Market Street.
There were no immediate riot-like problems with any of the early celebrations.
The celebrations are causing street closures and significant delays for traffic and public transit as well, according to the Department of Emergency Services.
Larkin and McAllister Streets near Polk in the Civic Center are closed and residents are advised not to drive this evening unless necessary, according to city officials.
San Francisco police were out in force to keep things safe.
They had to deal with the same thing two years ago.
The night the Giants won the World Series at 2010 there were only a few arrests for public drunkenness.
The 2010 damage report included one patrol car damaged, at least three private vehicles had their windows smashed, a window of a Giants' dugout store was broken, and one couch was destroyed after being lit on fire and tossed out a window. There were also reports of graffiti on store windows in the Mission district.
