According to the LA Times, Los Angeles Police Department Sgt. Sanford Rosenberg said the victim was one of three Giants fans attacked in the parking lot around the end of the game by two unidentified men wearing Dodgers clothing.

The unprovoked attack occurred about 8:30 p.m. in Parking Lot 2 when two men in Dodgers clothing approached three victims in Giants apparel, police said.

The men then attacked the trio, kicking and punching them and shouting expletives about the Giants as they delivered the blows, Rosenberg said. The attack left one victim hospitalized in critical but stable condition, Rosenberg said.

The Giants-Dodgers feud is one of the longest rivalries in sports history, dating back all the way to when both teams were in New York. This offseason, a group of Giants fans raised money to fly a banner over Dodgers Stadium reminding their rivals of their World Series win. Despite the incident, there were less arrests this year than last year’s Opening Day.
