The retractable roof at T-Mobile Park is one-of-a-kind, designed to cover the field from rain without fully enclosing it.

The roof weighs 22 million pounds, covers nine acres and was built with enough steel to build a 55-story skyscraper.

It takes about 10-20 minutes to close the roof with the push of a button, depending on the weather and wind conditions.

The roof is made up of three different panels that run on 128 steel wheels powered by 96 electric motors.

It is built to withstand up to 6-7 feet of snow and sustained winds of 70 mph, and it's even self-grounded in the event of lightning strikes.

Mariners Opening Day is Thursday

Catie Griggs, President of Business Operations of the Seattle Mariners, stopped Good Day Seattle to preview Opening Day and the upcoming season.

What happens if a ball hits roof trusses?

According to the Mariners, if a batted ball strikes a roof truss over fair territory, the ball is in play. If caught by a fielder, the batter is out. Runners can advance at their own risk.

If the ball is in foul territory, it's a dead ball.
