Imagine: Sitting before you is a scale model of the Rogers Centre, roughly the size of a round roasting pan. Your challenge: to put a real baseball field in the stadium – natural grass with a dirt infield — by opening day 2018.
Your research has been thorough. Experts at the University of Guelph have determined the ideal species of grass. They have it growing on an Ontario sod farm. They say it will flourish indoors with the roof closed.
Under the right conditions, that is. Your job is to create those conditions.
So open the roof, reach in and toss out that artificial turf, which was new for the 2015 season. Haul out your jackhammer. Rip up the concrete. Install plumbing for irrigation and drainage. Dig some more to accommodate the sod and the dirt infield.
Close the roof. Strip that shiny skin from the four mammoth roof panels. It’s the original PVC membrane, circa 1989, and it’s worn out. While you’re at it, you might figure out a way to replace it with a material that lets in the light. Grass likes natural light, and right now, the closed dome shuts it out.
The scientists at Guelph say the grass will grow without natural light, but you’ll need lots of artificial light – enormous banks of mobile “grow lights” that sit about 10 feet off the ground and nourish the sod when the field is not in use. You’ll roll them around between games to focus on the worn spots, even after games played with the roof open.
One more thing. Grass sweats. (Scientists call it transpiration.). Water from the roots vaporizes from the leaf surface into the air. All of that grass will create a lot of humidity, and you’ve got to figure out a way to get rid of that sticky air or the Rogers Centre will become a sweatbox with the roof closed. So you’ll need a dehumidifier. Forget Home Depot; you need a really big one.
Now you’re ready to install the grass.
Assuming, of course, that your engineers surmounted all of those challenges and you have the budget to make it happen.

Except for the 2018 deadline, all of the foregoing is fantasy. The grass is not growing. The University of Guelph has not begun the serious business of testing grass species. The Jays’ engineering team continues to investigate the enormously complex logistical challenges. They have visited stadiums in Milwaukee, Miami and Arizona, among others, to see how officials there have dealt with airflow and light issues.
Of course, there is a fundamental difference between the Rogers Centre and those facilities. Those other stadiums are baseball parks, engineered to grow grass. The Rogers Centre is a multi-use indoor entertainment facility engineered nearly three decades ago without grass in mind.
