Well, the headline kind of speaks for itself in this case, doesn't it?
Surveillance footage shows a fan recently breaking into Miller Park, home of the Milwaukee Brewers, taking the liberty of hopping on a tractor and using it to write his name on the field:
The man, Keyon A. Lambert, was charged with a felony, as he's accused of criminal damage to property and misdemeanor disorderly conduct. Chris Bumbaca of USA Today says that the belief is Lambert's antics created $40,000 worth of damage.
It's not immediately clear how quickly the Brewers were able to rectify the situation and correct damages done to Miller Park, which opened in 2001. Luckily(?), the incident occurred in June, when MLB was on their COVID-19-induced respite. The 2020 season didn't begin until late July, so whatever damage Lambert did to the field never affected gameplay.
