“I just tried to hit as many greens as I could and just play solid the whole day and try to putt at a great speed and if I make some putts it’s great,” said the Frenchman.
“I don’t know how it has gone that fast but I am just trying to do my job the best that I can and doing the best thing I can every day.
“It puts me in this place because I work the right way so I’m just trying to keep going and do the same thing every day.
“Today doesn’t matter. I just try to do everything great and we’ll see where it puts me at the end of the week but obviously I’m working for that and I’m ready to face everything.”
