I putted probably the best I've ever putted

“I putted probably the best I've ever putted,” he said.
"It's a tough course mentally coming down the stretch. It's not super narrow, but it's just if you hit it a little bit wayward it can cost you.
"I wasn't thinking much of the (seven-shot) deficit. I was just trying to play a good round of golf and get into next week on a high. I was finishing the last hole yesterday very bad (with a double bogey).
"I was pretty angry after the round and then took a long rest and tried to just have a good day. I came out holing putts on one and two, so anything can happen from there."
