CHARLOTTE, N.C. - Just 66 days left until the opening tee shot of the 2017 PGA Championship.

On Monday Quail Hollow Club hosted PGA Championship Media Day. 2016 PGA Championship winner Jimmy Walker was in attendance.

Other notable attendees included Charlotte Mayor Jennifer Roberts, Hornets center Cody Zeller, and several representatives for the Panthers.

After undergoing significant changes to several holes, the course appears to be in great shape. Now, over the next 60 days it's all about building the necessary infrastructure.

"We're building the equivalent of a 25-story office building out here this summer if you add up all of the square footage that we've got going," Championship Director Jason Mengel said. "We're going to have about 300 separate structures out here. Some of those are what we've started already. Our championship shop is like dropping a Belk into the middle of the course."

As for the changes to the course, Walker approves.

"I like the way they've kind of opened it up a little bit. It seems like you can see through the course a little better than you used to. They had to make room for stands and grandstands and all of the stuff that goes along with hosting a major championship. It's a big deal. I think they're going to pull it off just fine."

Quail Hollow Club will host the PGA Championship August 7-13.
