What They're Saying

Jordan Spieth: "Just another round of golf. This was the third round I have played since the U.S. Open. I'm getting on-course reps and it is making a difference. The putt at 16 was really big. I knew I had a lot of birdie holes left. Kind of needed to steal one that I maybe didn't think I would get."

"I think today was a big day," he added. "I made a huge step forward based on how I felt when I was going to bed yesterday. I wasn't feeling good about my game and to come out and shoot a round like this when I didn't feel like tee to green I was very strong. Just made it work and took advantage of a couple of holes."
