Jordan Spieth says his confidence remains intact despite missing consecutive cuts

Defending champion Jordan Spieth insists his confidence remains high as he looks to bounce back from missing consecutive cuts for just the second time in his career in the Dean & Deluca Invitational.

Spieth missed the cut in the Players Championship a fortnight ago and suffered another early exit from last week's AT&T Byron Nelson, where his second-round 75 included a quadruple-bogey nine on the 16th after hitting two tee shots out of bounds.

The last time the two-time major winner suffered such a run of bad form came in the same year as he won the Masters and US Open, the 23-year-old following missed cuts in the first two FedEx Cup play-off events by finishing 13th in the next and then winning the Tour Championship.

"I feel more confident tee to green right now than I did last year, I feel more confident tee to green than I have probably in my career," Spieth said.

"I feel very comfortable over the ball, I've been putting myself in positions to shoot low scores and just haven't quite converted to the level I have in the past. I feel good about the state of my game."

Spieth - who has reverted to his old putter after experimenting with a new one last week - birdied the last three holes 12 months ago to win a PGA Tour title in his home state of Texas for the first time, with Colonial member Ryan Palmer finishing four strokes behind in third.

"It's always a highlight on my schedule," Palmer said. "Last year I was leading through eight holes on Sunday and of course your mind always goes back to that moment. Was there something I did wrong? Something I could've done different to be there at the end?

"It was awesome being in that atmosphere with the amount of friends and family I had watching."
