Clemons rallies
In a thrilling twist, Olesen holed his bunker shot for a birdie to pile the pressure on his opponent, but Clemons responded to that counterpunch and made his putt for a hole-winning two to pinch another hole back.
University of Arkansas student Olesen went five-up again, however, on the 30th and got a fortunate break on the 31st when his wayward approach ended up in a favourable lie on the adjacent tee and he halved the hole.
Five down with five to play, and with defeat staring him in the face, Clemons kept the contest alive with a mighty birdie putt across the green on the 32nd.
The 22-year-old’s hopes of pulling off a great escape suffered a terminal blow on the 33rd, though, when he had to take an unplayable lie after his drive buried itself in a tangle of rough.
Clemons conjured a fine recovery and found the green, but he couldn’t salvage his par and Olesen had the luxury of two putts for the title.
Olesen’s morning move
The foundations for Olesen’s triumph were laid in the morning’s opening 18-holes as the Dane forged a crucial advantage.
Clemons had struck an early blow with a birdie on the third to move one-up – it was the only time he was leading all day - but a ruinous run of four bogeys over the next five holes saw that advantage swiftly evaporate as Olesen moved three-up.
Clemons, who was aiming to add The Amateur Championship to the Scottish Open Amateur Strokeplay title he won at Muirfield earlier in the month, managed to reduce the leeway with a birdie on the par-5 13th.
A superb chip from just off the 14th green to within gimme distance gave him a chance of clawing another hole back but Olesen bravely holed a testing 12-footer for a half. The Dane’s vigorous fist-pump underlined the significance of the moment.
Clemons was then left to rue a three-putt bogey on the 15th as Olesen increased his lead to three again, but Gog Magog member Clemons quickly countered with a putt of 30-feet on the 16th for a hole-winning birdie.
Olesen stood firm and maintained his two-hole advantage before completing his conquest in the afternoon and becoming the 129th Amateur champion.
As Olesen celebrated, there was disappointment for beaten finalist Clemons.
“I usually pride myself on playing by best golf when it matters and when the pressure is on, and I didn't do that today,” he lamented. “I didn't play well enough to win, simple as that.”
