If they put fake grass in I will never attend another game. I'm serious. Disgusting. Totally unacceptable.
Thankfully, I've never attended a major league game played on artificial grass (15 different ballparks through the years - Brewers (County Stadium and Miller Park), Red Sox, Yankees, Mets, Orioles, Phillies, Cubs, Reds, Pirates, Cardinals, White Sox, Dodgers, Padres, Angels).
