Jordan Spieth misses cut at The Players Championship, already looking ahead to AT&T Byron Nelson

A second round 71 wasn't enough for Jordan Spieth (-1) who missed the cut at The Players Championship by a single stroke.

Now, he gets an early head start on preparations for his Dallas homecoming in the AT&T Byron Nelson next weekend.

Spieth missed the cut at TPC for the second straight year, and his game felt even worse being in the same group with tournament leader Jason Day the opening two rounds.

Spieth said it was no different than watching Day when he opened with a 61 on his way to an eight-shot win at the BMW Championship last September, or playing with him in the final group at the PGA Championship when Day became the first player to post 20-under par at a major.

"The Jason Day I saw the first two rounds at Chicago is about the same as the Jason Day now," he said. "That's pretty special. He's not really missing golf shots right now."

The 22-year-old Texan had his own problems, mainly with his putter, which he said he neglected while working on his full swing.

Jason Day set the 36-hole record Saturday morning at TPC and built a four-shot lead going into the weekend of golf's richest tournament.

The world's No. 1 player has yet to make a bogey in two days, and he feels capable of making every putt.

"The 36-hole scoring record is great and all, but I'm looking at the big picture," Day said. "I need to knuckle down here and try and keep pushing forward. And we've got two more rounds left, so there is still a long way to go."
