Players experience US Open roof for the first time

There's something different about the US Open this year, and it'll be hard to miss it when you're in Flushing Meadows. The new Arthur Ashe Stadium roof has arrived, making the New York City Slam the third major to have protection from the elements for the players (and fans).

The likes of Rafael Nadal and Garbine Muguruza are already in the city, practicing under the $150 million, 6,500-ton steel cover.

The qualifying tournament is underway, and some of those players (like the United States' Daniel Nguyen) have ventured over to the stadium for a peak of the craftsmanship.

The roof is designed to open or close in just seven minutes. Rain or shine, the show will go on.
