Day would have to finish outside the top 10 while Johnson won to lose the No1 spot, and that thought is enough to motivate the Australian, who was tied for fourth in golf's oldest Major a year ago at St Andrews.
A terrific 10/1 price boost is available for any of Jason Day, Dustin Johnson or Rory McIlroy to win The Open. If I focus on myself and make sure that I'm playing the best that I can, I'm pretty confident that ...
"Who else could withstand the chaos this Sunday of the US Open?".
The U.S. Open champion withdrew from the Olympics late last week because of concerns over the Zika virus. "I like the big tournaments", Lowry said.
"First time I played the Postage Stamp it was quite a nice day", he told.
The 29-year old's performance at Oakmont was further proof of his ability to shine on the big stage. Not really, thanks to his recent back injury, but he's certainly in better form than Clarke or Els were before their wins, and he's very much in the mold of Zach Johnson or Padraig Harrington in the years they won.
VisitScotland chief executive, Malcolm Roughead, said: "Golf is a vital part of the visitor economy with the ripple effect felt in shops, hotels, restaurants and a wide variety of other businesses across Scotland".
Another Major, another chance for Westwood to end his drought and finally gain long-overdue admittance to golf's most exclusive club. "We're not going to win every single one".
With Tiger Woods missing his third straight major and still unsure of when or if he will return to golf after multiple back surgeries, Phil Mickelson will carry the can for the older generation.
The mystery is Royal Troon, a links Johnson had never seen until he arrived after a weekend in Ireland. There's nothing to suggest that Royal Troon can't provide the setting for Westwood's fairytale?
The jug for the previous year belonged to Johnson, who poured wine from it one last time on Sunday night at a house he is sharing with players. More often than not, too, the Open champ has previously won a major championship, making him respectable and familiar like a Graham Greene novel or that Tennyson poem we're all supposed to know. "So if you hit a solid golf shot here into a crosswind, the ball is going to get moved five, 10, 15 yards depending on how strong that wind is".
"What are you doing to our Olympics?" Three weeks later, he won the PGA Championship with such a dominant display of power that he became the first player to finish at 20-under par in a major. If the tradition is to continue, Kuchar is one of the most likely candidates to maintain the record.
Johnson and his fellow Americans might be pleased to know that the last six champions at Troon have hailed from across the Atlantic, ranging from the legendary (Arnold Palmer in 1962, Tom Watson in 1982) to the unheralded (Todd Hamilton in 2004, the last time the Open was played at the course).
Andy Sullivan watches his drive during practice at Royal Troon Golf Club.
Day, 28, says it was last year's heartbreak at St Andrews - both he and Spieth, playing in the final group, missed the play-off by a single shot - that gave him the strength to win the USPGA at Whistling Straits the following month.
Another zinger from a player who has no intention of fading away. I'll try to be creative.
Tyrell Hatton tees off during Day three of the Scottish Open at Castle Stuart.
