Dodgers and Giants fans have an extensive history of fighting each other when they get together. They proved on Opening Day, they don't even have to fight each other.
Dodgers fans threw hands with each other, more than once in the stands as their team took a loss on the field. What a start to the season.
At this pace the Dodgers will have at least 162 fights at their 81 regular season home games. We will, of course, have to recalculate for the postseason.
