Jordan Spieth at Tour Championship 2016: Sunday Leaderboard Score, Reaction

The PGA Tour will have to wait for its first back-to-back FedEx Cup champion.

Jordan Spieth carded a two-under 68 in Sunday's final round to bring his overall score to even par at the Tour Championship, going into the clubhouse in a tie for 16th place and 11 strokes behind the leaders.

"This tournament, a little bummed to not have given anything a chance," Spieth said, per Chris Vivlamore of the Atlanta Journal-Constitution. "Now it looks like, if I’d won, D.J., in fact at least at the present moment, is far enough down where I could have captured the cup."

Continuing his inconsistent trend, Spieth carded five birdies against three bogeys in an up-and-down round. It was his first round in the 60s since his promising two-under Thursday seemingly put him in position to contend through the weekend.

Hole	1	2	3	4	5	6	7	8	9	Out
Hole	10	11	12	13	14	15	16	17	18	In	Total
Par	4	3	4	4	4	5	4	4	3	35
Score	5	4	4	3	3	4	4	4	4	35
Par	4	3	4	4	4	3	4	4	5	35	70
Score	4	3	3	4	4	3	4	3	5	33	68

But it was not to be.

Spieth went a combined four over in the second and third rounds, recording matching 72s to enter the day 10 strokes off the lead. He would have needed a heroic round at the par-70 East Lake Golf Club in Atlanta, which had not produced a round better than 66 until Sean O'Hair went five under earlier Sunday.

Instead, Spieth began his final round of the 2015-16 PGA Tour season behind the eight ball. A pair of errant drives on Nos. 1 and 2 left him scrambling to save par, ultimately missing long putts on each to start two over.

As soon as Spieth found the fairway, his round began turning around. He earned back-to-back-to-back birdies on Nos. 4 through 6, draining a 20-foot putt on the par-four fourth to give him momentum. The fifth saw him hit a beautiful approach to within three feet for a tap-in birdie, and he two-putted the par-five sixth for his third birdie of the round.

Spieth missed a chance at a fourth straight birdie on No. 7, which started a five-hole cold stretch. He made the turn at even par after missing the green on the par-three ninth and then striking a 16-foot putt more than five feet past the hole.

With his bogeys behind him, Spieth played one of his cleanest nine-hole stretches of the tournament on the back, where he didn't come close to carding a bogey on any hole while adding a pair of birdies on Nos. 12 and 17.

For the round, it was a mixed bag. He hit half of his fairways and less than 60 percent of his greens, both below the tournament average, and wound up with less than a stroke gained on the putting surface. 

Finishing 16th during most weeks would look like a strong building block to take into the Ryder Cup. Unfortunately, the Tour Championship consisted of just 30 players—29 after Jason Day withdrew with a back injury. Spieth, playing against the best collection of golfers on tour, finished with a disappointing middling performance.

A year after taking the world by storm, Spieth finished his PGA Tour season with two wins, none since May. The hopes of Tiger Woods-like dominance seem quaint now as Spieth sits fourth in the Official World Golf Ranking, looking up at Day, Dustin Johnson and Rory McIlroy.

At 23 years old, Spieth should have a lot of great golf ahead, but this wasn't the way he hoped to finish out his PGA Tour season.
