BOSTON — Police in riot gear cleared several large crowds gathered around Fenway Park early Monday after the Red Sox won their second World Series title in four years. Police said they made 37 arrests, mostly for disorderly conduct.

Thirteen people were arrested after they refused to leave the Kenmore Square area near Fenway Park, police said. After police told a large crowd to leave, several officers were struck by rocks and bottles. Sixteen cars in one area were vandalized.

No serious injuries were reported.

Young people sprayed each other with beer and some climbed street signs or utility poles.

"Two World Series in four years is pure heaven," said Andrew Dumas, a Boston University student from West Boylston.

Police shut down access to Kenmore Square as Game 4 neared its end in Denver Sunday night. The Red Sox won the game 4-3, touching off celebrations around New England.
