Player Quotes
Thriston Lawrence:Â It’s been lovely. Everything seems to be working well. I’ve made three eagles in six rounds so that’s six under just there.
I’ve been hitting it nicely off the tee and putting nicely for a change. I know this golf course quite well so I’ve got great confidence on the greens.
The first two holes into the wind were crucial for me. I made two nice two-putts for pars there, and then on the third I hit it to three foot for the first birdie.
That gave me some momentum, and then the fourth and fifth holes were downwind and I made two good birdies there. There were a few sneaky pin positions out there but I managed to keep my approaches on the right side of the hole.
I’m happy for where I am now. Obviously there’s a lot of expectations but I’m just going to go out and do what I do, it’s still a normal day on the golf course.
