That win-rate was always going to be unsustainable.Considering his impressive stats and results, analysts have struggled to pinpoint exactly what has been wrong with Scheffler this week.Why has he failed to win more than once? Nobody seems to have a definitive answer to that question.However, after his second round at the 3M Open, we might just know exactly why Scheffler hasn’t been at his brilliant best over the past five or six months.Photo by Andrew Wevers/Getty ImagesThe 30-year-old world number one was bogey-free through 31 holes of the tournament until disaster struck on the 14th hole.Why Scottie Scheffler has struggled in 2026 becomes clear at the 3M OpenScheffler made a double bogey six on the 14th after finding the water with his approach shot from the middle of the fairway.Of course, anyone can make a double bogey at any given moment.However, it was the way that Scheffler succumbed to the double bogey o
