Jordan Spieth at AT&T Byron Nelson 2016: Saturday Leaderboard Score, Reaction

Jordan Spieth remained in the thick of things at the AT&T Byron Nelson on Saturday at the TPC Four Seasons Resort in Irving, Texas, shooting a three-under 67 to go to 14 under for the tournament.

He trails leader Brooks Koepka (16 under) by just two strokes.

Here's the leaderboard heading into Sunday's final round:

Spieth played another solid round Saturday, finishing the day with just two bogeys (on Nos. 14 and 18) and five birdies. Though he battled some adversity—namely with an erratic driver and a swing that seems unsettled—he managed to keep himself in the running on a day when he could have fallen off the pace.

Nonetheless, he acknowledged he wasn't at his best on the afternoon.

"I just don't have confidence over the ball right now," he said, per Kyle Porter of CBS Sports.

Spieth spoke in more detail about those struggles, per Brad Townsend of the Dallas Morning News:

Still, he looked good early.

He wasted little time hitting his stride, earning a birdie on No. 3 with a fantastic approach and putt, as the PGA Tour shared:

Birdies on Nos. 7 and 9 rounded out a strong front nine. The PGA Tour shared a replay of his putt on No. 9:

From there, Spieth birdied Nos. 11 and 17.

No holes were more indicative of his day than Nos. 17 and 18. He whipped the crowd into a frenzy on No. 17 with a brilliant birdie putt, via the PGA Tour:

Then came No. 18.

Spieth's drive veered far to the right into the crowd and the trees, leaving him with a difficult approach shot. He managed to clear the trees and lay up on the green, giving himself an opportunity to finish his day with a par.

Not surprisingly, his third shot was perfect, setting up a manageable putt for par. But unlike many of his other saves on the day, this time Spieth's struggles caught up to him, as he missed his putt and settled for a bogey on the final hole.

Still, given his inconsistent play on the day, Spieth's 67 was a strong showing. It's safe to say that his day could have gone worse.

And most golfers would take the sort of round that Spieth considers an off performance, as Porter noted:

The final round promises to be a thriller. Koepka, the leader, has been playing fantastic golf. Meanwhile, Matt Kuchar, Bud Cauley and Sergio Garcia, who are all just three strokes off the lead at 13 under, are capable of making a final push to win the tournament.

Catching Koepka will be a struggle. He's been the tournament's most consistent player, with two rounds of 65 and Friday's 64.

Spieth praised Koepka after Saturday's play, per Jason Sobel of ESPN.com:

And it will be a final round round of twos: a two-stroke lead, Koepka gunning for the second title of his career, Spieth going for his second title this year and the second time this season that Spieth and Koepka will have played together in the final group.

There will be no shortage of reasons to watch. Chief among them, however, will be seeing whether Spieth can regain his confidence over the ball.

If he regains his form in that facet of his game, Koepka and the field's other contenders will have a hard time keeping Spieth off the top of the leaderboard.
