“He could have shot 63,” said playing partner Darren Clarke, the 2016 European Ryder Cup captain.
"Yesterday was just a very special day for me," he said. "Even though I shot 9-under par yesterday ... if people want to talk negative about it, I then shot six shots worse. But you can always go in the negative. I see very positive things that I backed up that 9-under par with another decent round."
