Koepka on Quail Hollow: 'Fastest greens I've ever played'

Quail Hollow has undergone some major renovations since May 2016, but it's the new Bermuda-grass greens that have really grabbed the players' attention at this week's PGA Championship.

After posting an opening-round 68, Brooks Koepka said the speed of the greens on Thursday was unlike anything he's ever experienced on a golf course.

"With some of the pin locations, these greens are the fastest greens I've ever played," said Koepka. "And the thing is, they are only going to get faster and firmer."

Koepka added the pace of the putting surfaces prevents players from being aggressive with birdie opportunities.

"These greens are so fast, it's so delicate...you're just kind of worried about running it by (the hole) sometimes."
