Wrigley

In July 2004, there were three reports of chunks of concrete tumbling from the upper deck at Wrigley Field, prompting the Chicago Cubs to install protective netting and review stadium infrastructure, according to the Associated Press.

Dodger Stadium, which opened in 1962, is the oldest Major League Baseball stadium west of the Mississippi and the third oldest in the nation, after Fenway Park in Boston and Wrigley Field in Chicago — both of which have also experienced issues with aging concrete.

Mars' Wrigley division bought the brand in 2009.

“When you’re 5 years old and you’re watching the Cubs play a day game at Wrigley Field, all that matters is that day’s game,” Randazzo said.

Fenway Park, the oldest professional sports stadium in the U.S., was built in 1912, two years before Wrigley Park opened.
