His heart was beating so fast that Jon Rahm couldn't think as he studied the 60 feet from his golf ball on the back fringe to the cup at the bottom of the slope on the 18th hole at Torrey Pines.
The 22-year-old from Spain had enough wits to seek advice from his caddie, Adam Hayes, who had seen this putt before.
The idea was to get to the slope. Rahm did better than that.
He sent it off to the left and made sure it reached the crest, then watched it peel off to the right and start tracking back to the left until it disappeared into the hole on the final turn for an eagle , the winning shot Sunday at the Farmers Insurance Open and one he won't forget.
