“To be honest, I had no idea what to expect after that poor first round,” said Knox, who needs to win the event to have a chance of claiming the FedEx Cup and a whopping bonus.
“I was really just hoping to get a little bit of momentum going and what I’ve done has put myself back in the mix and that’s super.”

“I had five birdies,” reported Pretswell. “I’ve only used driver three times in the last two days so I’ve been hitting a lot of 3-woods off the tee to get my rhythm.
“I’m not one of the ones that likes to hit driver everywhere. I’m happy to mix it up with whatever I need to hit off the tee to just get myself into a good position.”
Scottish-based American Beth Allen is also in the mix, sitting third on four-under, while Laura Murray is six off the pace in joint-ninth after maintaining the form that landed her a win on the LET’s development circuit in Sweden last week.

“When you look around at all the distinguished past captains it makes you feel pretty intimidated and humble really. I am very much looking forward to serving as captain and representing the Club.”
