It's happened again. Just about a month since Sporting Kansas City had a match interrupted when sprinklers went off when a grounds crew member accidently activated an app, the restart after halftime when the Houston Dynamo hosted the LA Galaxy was delayed for five minutes by sprinkler madness. You have to feel for the poor stadium employee trying to turn off the system manually, which apparently is kept inside a hobbit hole.
The players had a bit of fun with it.
