Padre Blog GasLamp Ball provides some details.
I saw that on Friday night and it was one of the craziest things I have ever seen at a game. I was in the bleachers and that was in the upper deck. I looked up and saw a bunch of people standing up and running out of a section with drinks flying everywhere. This video only catches the tail end of it where the padre fans are leaving. The 3 or 4 padres fans for some reason just sat there for about 2 minutes while the section cleared out and that is when things got ugly. I saw at least 25 beers fly at them and hit them hard. security did absolutely nothing, it was amazing. the security was terrible all night there...i saw a few girls in my section get their padre hats knocked off their heads and thrown around and then tons of peanuts thrown at them.It does get a little crazy up there.
