Jordan Spieth at British Open 2015: Sunday Leaderboard Score, Twitter Reaction

Jordan Spieth doesn't seem keen on allowing any other players to win a major championship this season.

The phenom surged into a tie for third place at the British Open on Sunday, shooting a six-under 66 to put him at 11 under for the tournament, one shot off the lead.

He also remains within striking distance of making history, as Jason Sobel of ESPN noted:

Don't expect Spieth to feel the pressure too much, however.

"Right now I feel even more calm than the [U.S.] Open, when I was certainly feeling better than the Masters," he said after his round on the ESPN broadcast. "I have a little more experience in this position than I did in the previous major."

He added, "I did what I needed to do today. ... I'm going to sleep fine tonight," per Golf Digest on Twitter.

Still, a crowded leaderboard will present him with quite the tall task Monday.

It should make for a memorable Monday and, with history on the line, one that will be excellent for the sport of golf, as Albert Breer of the NFL Network noted:

Spieth certainly started his day on the right foot, with an impressive birdie alongside playing partner Sergio Garcia. The Open on Twitter passed this along:

Birdies on Nos. 5 and 7 had Spieth creeping up the leaderboard, though a bogey on No. 9 was a disappointing way to close out the front nine. 

And then he caught fire.

Spieth promptly birdied the first three holes on the back nine and put himself in a tie for the lead with another birdie on No. 15. He then made a huge putt to save par at No. 17, though, as Sobel noted, saving par is nothing new for Spieth:

Spieth was as steady as it gets Sunday, hitting 81 percent of the fairways and 78 percent of the greens in regulation and averaging 312 yards on his drives, per TheOpen.com. He also cut down on his putts significantly, per Justin Ray of the Golf Channel:

It's a testament to Spieth's talent, poise and dominance that it is so hard to imagine him failing to outplay the field Monday. Indeed, Ben Smith of the BBC found himself marveling at the young golfer Sunday:

It's Spieth's cool temperament that seems to be his greatest ally.

"It's just a matter of playing to my strengths—playing aggressively but being patient enough to let the holes come to me," he said, per the ESPN broadcast. 

That's what he's done in his previous two major wins, and it seems to be a formula that is working pretty well.

On Monday, the pressure feels as though it will be on the field, not Spieth. Because Spieth, and anybody who has watched him this year, knows that he will show up. He'll post a good score. He'll save par. He'll make the clutch putts. He won't be intimidated by the stage or spectacle of the British Open.

It's on the other contenders to prove they can do the same. And to this point in the 2015 majors, no one has been up to the task.
