How the Toronto Blue Jays ground crews keep the field in pristine shape
The Weather Network spoke to the ground crew at the Rogers Centre about how weather impacts the Blue Jays' baseball field.
There are 30 Major League Baseball (MLB) stadiums, but only seven have retractable roofs.
While that allows field crews to keep conditions fairly consistent on the diamond during cold, rainy or even snowy days, open-roof days shine a light onto a particular problem.
Ben Jamieson, manager of field operations for the Toronto Blue Jays, talked about the different types of clay that is incorporated on the diamond--something not many people are aware of.

For example, the grey clay is used in the batter spots and pitching mounds.
"So, this is our toughest clay, our hardest clay," said Jamieson.
The team also uses a red clay for the mounds, and is there because it's more durable than other types, Jamieson said.
As for why the ground crews water the clay so much, especially for day events when the sun is shining bright, "we need to really keep that clay soft," he said.
Whether it comes to man-made our nature-made, weather still plays a big role when it comes to your baseball viewing.
