During the 2013 Wells Fargo Championship, a golf course superintendent stood on two of his greens and watched his crew tear them apart mid-round. Players were still on the course. What the broadcast didn’t say was that all eighteen greens were already scheduled for demolition the moment the last group finished on Sunday.
The grass was Penn G-2 bentgrass in Charlotte’s transition zone — hardiness zones 7b and 8a, where shoot growth ceases above 90°F and root growth stops at 77°F soil temperature. After brutal summers in 2009 and 2010, the biology had been building its verdict for three years. NC State agronomy professor Fred Yelverton stood on those greens during the tournament and said he’d never seen greens fail like that anywhere. The PGA Tour declared two greens unacceptable for tour play while the championship was still being contested.
The first replacement was MiniVerde ultradwarf bermudagrass. It failed too — off-type contamination, documented by the USGA Green Section as early as 2009, producing the same splotchy, inconsistent surfaces bentgrass had before it. By the time Keith Wood arrived from Sedgefield Country Club in 2015, the MiniVerde was already going patchy. His assessment of the 2016 Wells Fargo, with the 2017 PGA Championship fifteen months away: four words. “We got by.”
On May 8, 2016, construction crews were on the front nine before the final group reached the scorer’s tent. Eight hundred trees came down the next morning. Twelve weeks to complete what normally takes five to six months. Champion G-12 ultradwarf bermudagrass, sourced from a Texas farm and bedded in 400 tons of worm castings from Southern Organics in Cheraw, South Carolina. The 2017 PGA Championship opened on greens that had been in the ground for less than twelve months. Rory McIlroy called them the firmest he’d ever seen at a PGA Championship. Brooks Koepka said they were the fastest he’d ever played. Players estimated a Stimpmeter reading near 14.
The same reading Augusta produces every Masters week on bentgrass it’s been conditioning for decades — with SubAir, a five-month closure, and a maintenance budget with no public ceiling. Same Stimpmeter speed. Three different grasses to get there. The greens running at this week’s Truist Championship are those same Champion G-12 surfaces. They’ve held through the 2022 Presidents Cup and the 2025 PGA Championship. Most people watching on television have no idea.
