It was a foggy day in Chicago.
While the Cubs and Reds had some difficulty playing their game at Wrigley Field due to the fog, the White Sox-Blue Jays across town at U.S. Cellular Field had to be delayed for over an hour.
"It was actually pretty tough," White Sox slugger Adam Dunn said about the fog after the game, via the Associated Press. "It was probably a lot tougher for the outfielders."
Dunn hit two home runs as the White Sox went on to win, 10-6.
The game at Wrigley Field was not delayed, but Cubs manager Dale Sveum wouldn't have been surprised if it had needed to be stopped.
"You used to see it at Candlestick Park and Oakland," Sveum said after the Cubs' loss, per MLB.com. "Obviously, it couldn't get any worse, otherwise you would've had to stop. It was borderline as it was. Growing up, I saw it plenty."
