Jordan Spieth has emphasised how positive he is feeling about his game ahead of this week's AT&T Byron Nelson in his native Dallas, declaring that "everything is starting to fall in place".

Spieth, yet to win a tournament in 2018, last month came joint-third at the Houston Open, then third at the Masters.

And he shot a seven-under 65 on Saturday at the Players Championship before dropping down the leaderboard on Sunday.

The 24-year-old three-time major and 11-time PGA Tour winner told a pre-tournament press conference: "I feel as good about my game right now as I have this entire year and even a lot of last year, so I feel like good things are coming.

"I've stayed the course, had a lot of patience recently. Everything is starting to fall in place.

"Everyone goes through kind of peaks and valleys with different parts of their game. I got a little off in set up in alignment with short game shots and putting, and (I'm) really starting to progress nicely, starting to see my lines better. Whether putts have gone in or not I've had better strokes.

"I was very comfortable on Sunday with Tiger (Woods).

"I felt like I didn't get a lot of good numbers. I had a lot of in between numbers on shots, and some putts that were... The speed was a little off or the line was a little off.

"But I was as comfortable as I've been in a pretty relatively uncomfortable type of situation this entire year, including even playing well at the Masters."

Spieth - who competed aged 16 in the 2010 edition of the tournament after writing to its chairman asking to be considered for a sponsor exemption, and finished tied for 16th - is a member at Trinity Forest Golf Club, a new venue for the event.

And he added: "Obviously (with) this course I feel like I'm at an advantage."

The press conference also saw Spieth asked for his thoughts on the United States Supreme Court overturning a federal law that effectively banned betting on sporting contests in every state apart from Nevada, paving the way for the other states to legalise sports gambling.

He said: "It's a very significant day in sport, for that to be overturned.

"I know the PGA Tour has stepped in and there are stricter policies for us and our teams regarding releasing information, and obviously we can't gamble ourselves on our sport, whether it's passed or not.

"People call gambling a vice. Now that you've made it legal and more open, it's kind of a personal decision I guess.

"I'm not very educated on it, but I imagine it will boost the economy of the states that allow it."
