British Open 2015: Leaderboard Scores and Highlights from Sunday

Pick a storyline, any storyline. Because on Sunday at the British Open, there was no shortage of them.

There was Jordan Spieth shooting six under and finding himself just a stroke behind the leaders as he seeks to win his third straight major. There was Jason Day, tied for first place and seeking his first major, and amateur Paul Dunne joining him at 12 under (along with Louis Oosthuizen). There was Dustin Johnson, playing poorly and dropping down the leaderboard, a particularly difficult afternoon considering his inability to close at the U.S. Open.

And, of course, there was the remarkable fact that 14 players found themselves within three strokes of one another at the top of the leaderboard after a day of perfect conditions at St. Andrews led to a slew of excellent scores. 

Here's the full leaderboard:

It's hard to argue that Spieth and Dunne aren't the most intriguing players to watch Monday, however. Spieth could join some pretty illustrious company if he manages to win his third major of the year, per Jason Sobel of ESPN:

Of course, Spieth doesn't seem all that bothered by the pressure, per the PGA Tour on Twitter:

On the other hand, it doesn't seem as though he would be shocked if Dunne pulled off the win, either:

Dunne, to his credit, has already made history, as Justin Ray of Golf Channel tweeted:

Dunne was excellent once again, shooting a 66—a course record for an amateur at the British Open at St. Andrews, per The Open on Twitter—to go with his two rounds of 69 coming into the day. That matched him with Oosthuizen, who duplicated the 67 he shot in the first round, and Day, who also posted a 67. 

Dunne is the long shot of all long shots at St. Andrews, as Chris Fowler of ESPN noted:

That sets up a final pairing of Dunne and Oosthuizen, while Day and Spieth will tee off just before them. It's hard to beat a final four that includes an amateur, one of the best players on the PGA Tour without a major championship in Day and the game's budding young superstar looking to make history in Spieth. 

Johnson was expected to be in one of the final groups after coming into the day in the lead, but he fell apart Sunday, shooting a shocking three-over 75 and finding himself five strokes off the lead, almost assuredly out of contention for the Claret Jug. It was heartbreaking for the player who was a putt away from winning the U.S. Open but couldn't seal the deal. 

Johnson's rough day was really the outlier Sunday, as the pristine conditions allowed for low scores throughout the field after inclement weather was such a major factor earlier in the tournament. That, in turn, led to some amazing shots, such as Andy Sullivan's eagle on No. 14, per The Open on Twitter:

Not to be outdone, Spieth and his playing partner, Sergio Garcia, got things off to a strong start on No. 1:

And Retief Goosen notched himself an eagle on No. 5:

It was one of those days Sunday, setting up what could be one of the most memorable final rounds in a major in quite some time. An amateur might make history. The game's young star might make history. Day might finally break through and win a major. Or a surprise contender could emerge and steal the show.

Given the way this British Open has transpired so far, well, anything could happen. Monday promises to present a whole new treasure-trove of storylines for golf fans to enjoy.
