Spieth had been put forward as a bold, win-only selection by Coley in his outright Open preview, having also been tipped when winning on his prevoious start.
"We are talking here about an exceptional player in Fowler, but an all-time great in the making in Spieth," wrote our man.
"Players like him don't come along often. He will win many more majors, quite possibly starting here.
"It's hard to be confident ahead of an event like the Open, but on a course widely considered among the fairest on the roster, which has produced a world-class roll-of-honour, largely players who had already won majors, the prospects of a top-class winner appear stronger than usual."
"The prospects of Spieth appear better than any other player and he gets the vote to show it."
Coley also put up Marc Leishman and Branden Grace, who shared sixth, to ensure another big return for followers of his golf tips - his outright preview made 56.5 points in total from 14 staked.
Overall, Ben's tips are upwards of 200 points in profit for 2017 after a similar return in 2016.
On Saturday, Ben Linfoot's Value Bet column proved once again that it is not to be missed on the eve of all major UK horse racing.
Linfoot previewed two races and found winners at 9/1 and 16/1, Bengali Boys' success at Newbury crowning yet another memorable weekend for our flagship tipping column.
"He’s one of the most consistent horses in the field having run to a good level on all three starts but I think we could see him take his form up a notch here now he encounters a big field and a bit of cut in the ground," wrote Linfoot.
"The conditions are Good to Soft (Good in places) at the time of writing but more rain is forecast and that could really suit this son of Clodovil, who has displayed a rounded high-knee action in his races thus far.
"He was a bit keen early on last time too, but you would hope he’ll be able to settle better and get some cover in a field as big as this - especially from his central draw.
"Given 54 days off since we last saw him, he’s had time to develop further and the form he’s already shown isn’t far off the best of these."

Spieth cut for US PGA
Jordan Spieth has the chance to complete a career grand slam at next month's PGA Championship, and Sky Bet make him an enhanced 10/1 to do it at the first attempt.
The Texan has won three majors in fewer than 20 attempts already, but Quail Hollow, hosting the event for the first time, is considered to be at the mercy of 7/1 favourite Rory McIlroy.
However, Spieth has won his last two starts and seems sure to be popular for another major championship.
Sky Bet's John Rhodes said: "Spieth is 8/1 in our book to win the grand slam next month, but we've enhanced that to 10/1 to see if we get any takers.
"He did incredibly well to win at Birkdale but it's questionable whether Quail Hollow suits him as well as it does the other big names."
