With two holes remaining during Saturday's third round at Wentworth, Jon Rahm was leading the BMW PGA Championship by two shots as he made his debut at the tournament, but some sloppy play from the Spaniard allowed Danny Willett to share the overnight lead.
Although the two were level at the start of Sunday, the bookies had Rahm as the clear favourite to go on to win the European Tour's flagship event, but after making mistakes at 12 and 14, Rahm opened the door for Willett who continued his fine form throughout the week and went on to win his seventh European Tour title.
Rahm's second-place finish is his seventh top 10 finish in his last nine starts, but reflecting on his performance, the 24-year-old was disappointed not to add another win to his list at Wentworth.
"I'm not going to lie, it hurts and it stings," said the world No 6. "I played good all week and, up until the 13th hole, I was incapable of hitting an iron close to the pin and made a couple of stupid mistakes.
"I should have come closer than two shots on the last two holes, so I had my chances. Again, I did what I had to do. Just had a couple of really stupid mistakes there, and I'm just going to have to figure out why it happened.
"That stretch of holes 11 through 14 was key. Even though I made that birdie on 13, those mistakes on 12 and 14 cost me a lot and that's why Danny came out on top.
"It's easy to fixate 18 because I hit it in the water, but there was moments out there I could have done a lot more. The first few holes, I had short irons into the green and good shots, and just couldn't hit it close and hitting 30-footers all day and I couldn't put any pressure.
"At the same time, after coming from three weeks off, it was a solid round and a solid tournament. I'm happy with the way I played, but it still hurts a little bit."
Rahm heads to Scotland this week for the Alfred Dunhill Links Championship, played across three courses, St Andrews, Kingsbarns and Carnoustie, where Rahm is the second favourite to win prior to the start of the tournament, behind Rory McIlroy.
