Syme went into the tournament ranked 836th in the world at the beginning of the week.
He finished a shot ahead of Steve Webster, Nicolas Colsaerts, Justin Walters and Raphael Jacquelin, and is expecting to make a huge jump in the rankings after his highest ever finished on the European Tour.
“It’ll really change my season for sure,” he said.
This week’s tournament was the first in professional golf to time each shot from every player in the field.
Players had 50 seconds to take their shot if they are first to play, including tee shots on par threes, or 40 seconds for tee shots on other holes or when second or third to play.
The first two days went by without a single time violation, but there were three on Saturday, with Clemens Prader, Scotland’s Grant Forrest and Andrea Pavan all handed one-stroke penalties.
“I absolutely loved it,” said Syme.
“With me being in contention, there may have been shots I would have stood off from, but with the time limit I knew I couldn’t. In that sense I think it helps the players.
-13 M Korhonen (Fin); -8 J Walters (SA); -9 Jeppe Huldahl (Den); A Wu (Ch); David Horsey (Eng); Peter Hanson (Swe); Adam Bland (Aus); Miguel Angel Jimenez (Spa); Connor Syme (Sco); Austin Connelly (Can)
Selected others:-8 Lee Slattery (Eng); -7 M Foster (Eng); Level G Forrest (Sco)
Clemens Prader became the first golfer to be penalised a stroke for slow play at the Shot Clock Masters and Scotland’s Grant Forrest soon followed in Austria.
Home favourite Prader took four seconds over his allotted time for a third-round putt on the sixth hole.
Forrest incurred a penalty when he took three seconds over the regulation 40 for an approach shot at the 15th.
Finland’s Mikko Korhonen leads by five strokes going into the final round.
The halfway leader recorded a four-under-par 68 to leave South African Justin Walters as his nearest challenger on eight under.
Englishman David Horsey, Scotland’s Connor Syme and veteran Spaniard Miguel Angel Jimenez were among the large group in a tie for third on seven under at Diamond Country Club.

Prader, who is last in the field after a 76, said: “I didn’t hear ‘time’.
“I was just in my routine and it must have been called sometime when I was walking to my ball, which is fine, I just didn’t hear it.
“It was just four seconds over, which is a little unfortunate.
“I was a little angry. It got me so heated that I actually holed a bunker shot on the next hole, which was OK, it kind of reversed it.”
Leader Korhonen told Sky Sports: “I always love to come here and it seems to be working well this year.”
World number two Dustin Johnson hit a seven-under-par 63 to take a one-shot lead after two rounds of the St Jude Classic in Memphis, Tennessee.
The American holed from 110 yards for an eagle and hit seven birdies and two bogeys as he moved to 10 under overall.
Irishman Seamus Power carded a 69 as he went from having a one-stroke overnight lead to trailing Johnson by four.
Americans Ryan Blaum and Andrew Putnam are a shot behind the leader after both went round in 64 on day two.
Brooks Koepka of the United States, a week before defending his US Open title, carded 69 to slip five strokes behind, while compatriot Phil Mickelson (70) fell six adrift.
“When you’re around or in the lead you can definitely feel the pressure – but I like it,” said Johnson, who won the US Open in 2016.
“I hadn’t played a whole lot the last couple of months. I felt it was more beneficial to play here and be sharp going into the US Open than to stay home and maybe go up there a couple of days early.”
Mickelson needs to win next week at Shinnecock Hills to become the sixth man to have claimed all four majors – the US Open, the Masters, The Open and US PGA Championship – and his second round included five birdies and five bogeys.
“I didn’t really have it today but I was able to close out the round with a couple of birdies and get it back to even,” said the 47-year-old.
“My iron play needs to be a little bit better. And when I miss a green I’ve got to be sharper around the greens.”
Venue: Quaker Ridge, United States Dates: 8-11 June
Despite a frustrating flight delay to New York, Great Britain and Ireland remain confident they can upset the odds and retain the Curtis Cup.
The match between the elite amateur women of GB&I and the United States begins at Quaker Ridge on Friday.
America boast a formidable line-up with all eight of their players ranked inside the world’s top 25 amateurs, including number one Lilia Vu.
But visiting captain Elaine Farquharson-Black believes her young team can repeat the stunning triumph they achieved at Dun Laoghaire in the Republic of Ireland two years ago and win on American soil for only the second time in the match’s 86-year history.
“We’ve been thinking about it and planning for what seems like a very long time,” Farquharson-Black told BBC Sport.
“We had a false start when the first plane didn’t take off and we had an extra night in London but we used that for everybody to get to know each other better.
“We were sitting on the runway for six hours because of technical faults. It started with the toilets not working at the back of the plane to then the intercom not working and then they cancelled the flight, so we flew on Wednesday instead of Tuesday last week.”
The average age of both teams is under 20 for a match that includes several players destined for the professional ranks. Only two players, Olivia Mehaffy and Alice Hewsen, remain in the visitors’ line-up from their victory in the last contest.
At 20 in the world, Mehaffy is the highest-ranked player in the GB&I team which includes 15-year-old Annabel Fuller and Lily May Humphreys, 16. The US have teenage sensation Lucy Li, who qualified for the 2014 US Open when she was only 11-years-old.
Farquharson-Black, who played in the 1990 and ’92 matches, is not concerned about the youthful nature of her team.
“I think playing golf gives you a bit of maturity,” she said.
“You are out there having to control your emotions and decision making. We’ve made sure they spend time with the more experienced ones when they go out to practice, to work on course strategy and management, but they are a lot of fun.”
GB&I made their final preparations at nearby Fenway and paid particular attention to shots on and around the greens that they expect to face at Quaker Ridge. Short-game expert Steven Orr was flown in to oversee the sessions.
“With a Curtis Cup match in the States it is generally won and lost on the greens,” Farquharson-Black said.
She was in charge when GB&I completed their stunning 11.5-8.5 victory in Ireland two years ago. “Somebody commented to me that it was the best golf they had ever seen in a Curtis Cup,” the captain said.
“We made a whole heap of birdies, I think 70-odd birdies over the three days. It was very good golf and we are going about things in the same way in terms of our prep here.”
With the Ryder, Walker and Solheim Cups all in American hands, the Curtis Cup is the only one of the big four transatlantic golf trophies currently held outside the United States.
“I’m not sure I’m looking at it in terms of us being the only ones out of all the different cups,” Farquharson-Black said. “I suppose I look at it that it was fantastic to win in 2016 and we don’t have a great record over here, so I think it would be pretty special.
“We have a very good chance because we have eight exciting players playing well, we will be prepared and ready when the whistle blows.”
The contest is played over three days starting on June 9 with three foursomes followed by three fourball matches on each of the first two days and eight singles on Sunday.
These are the two teams:
GB and Ireland
India Clyburn, 21, Woodhall Spa, England
Annabell Fuller, 15, Roehampton, England
Paula Grant, 24, Lisburn, Ireland
Alice Hewson, 20, Berkhamsted, England
Lily May Humphreys, 16, Stoke-by-Nayland, England
Sophie Lamb, 20, Clitheroe, England
Shannon McWilliam, 18, Aboyne, Scotland
Olivia Mehaffey, 20, Royal County Down Ladies, Ireland
Mariel Galdiano, 19, Pearl City, Hawaii
Kristen Gillman, 20, Austin, Texas
Jennifer Kupcho, 20, Westminster, Colorado
Andrea Lee, 19, Hermosa Beach, California
Lucy Li, 15, Redwood Shores, California
Sophia Schubert, 22, Oak Ridge, Tennessee
Lauren Stephenson, 20, Lexington, South Carolina
Lilia Vu, 20, Fountain Valley, California

A decade ago they were trying to out-do each other on the putting green at Dumfries & County Golf Club.
This week, Connor Syme and Liam Johnston are competing in the same European Tour event in Austria.
“If you’re being realistic, the chances of this were pretty slim, but we’ve both worked incredibly hard at it, so why not?” Johnston told BBC Scotland.
“I’ve known Connor since he was 12 or 13. We used to always play putting competitions at the club – and even some of them I can remember exactly how they finished.
“If you lost the putting competition, you had to go to the furthest pin on the course then bring it back. Then the loser of the next one had to take it back out.
“So you knew they had gone far enough to go and get it.
“That happened to Connor more, obviously.”
‘Win in Spain changed my year’
The entertaining way Johnston relays that story – in the company of a beaming Syme – indicates the great relationship the pair have but also that they simply just love their golf.
Syme, 22, is midway through his debut season on the European Tour.
Johnston, 25, has a win under his belt on the Challenge Tour, something that might help him make the step up for the 2019 season.
“To see a long-time friend get his card first year out, straight out the blocks, is a huge inspiration to try and get myself there as well,” said Johnston, whose younger brother, Ryan, is his caddie at the Shot Clock Masters this week at Diamond Country Club, near Atzenbrugg.
“My win in Spain changed my year completely, has given me a massive boost and totally changed my schedule for the rest of the year.”
‘We want to be back here next year’
Syme was born in Kirkcaldy but lived in the Dumfries area from the age of two until his late teens because of his dad Stuart’s job as the professional at Dumfries & County, a role now occupied by James Erskine.
Now based at Drumoig Golf Centre in Fife with his Dad as his coach, Syme’s maiden year on the European Tour has been an enjoyable one but has not been without its challenges, as he seeks to acclimatise at a level he admirably reached ahead of schedule.
In the European Tour’s Race to Dubai rankings, Syme is currently 206th and, over the summer, will seek to get inside the top 110 to be assured of keeping his card for 2019.
Johnston is 11th in the Challenge Tour’s Race to Oman rankings and, if he stays in the top 15, will win a European Tour card for 2019.
“If Liam and I are both on the European Tour next year then we’re both doing something right,” Syme told BBC Scotland.
“It would be awesome if we could both be back pegging it up next year.
“It’s class to be out here playing together in a European Tour event, something we’ve both been striving to do since we were much younger.
“We’re always messaging each other and keeping an eye on each other’s results.”
In an attempt to speed up the game, there is a 40-second limit to play each stroke at the Shot Clock Masters in Austria, but at least there’s no requirement to run to the furthest pin as punishment for a bad putt.
She made her fifth birdie of the day at the ninth but drove into the trees and ran up a triple bogey at the 10th, before dropping another shot when she failed to find the green in regulation at the 12th.
And when Kim, the 2014 Evian Championship winner, holed a putt from off the green at the 15th, for her fifth birdie of the day, the lead was reduced to a single stroke.
But after a long wait on the tee at the par-three 16th which she spent calmly sitting against her golf bag, Jutanugarn hit a majestic shot to three feet for another birdie.
When world number 67 Kim, playing in the penultimate group, missed a five-foot birdie chance at the 17th it appeared to hand the Championship to Jutanugarn.
But the Thai went through the green at the par-five 17th, duffed a chip and had to hole from six feet to only drop one shot.
Then at the last another shot went after she put her second shot into a greenside bunker and failed to get up and down in two.
The two-hole play-off began at the 14th and Kim holed another long putt from the edge of the green for birdie, but she found a bunker at the 18th to drop a shot, while Jutanugarn sank a four-foot putt to take the Championship to sudden death.
The players went back to the 14th, which they both parred.
That meant another playing of the 18th and both found a greenside bunker but Jutanugarn played a sublime escape to two feet while Kim’s pulled up 18 feet from the hole and she could not hole her par putt.
They had finished four shots clear of Spain’s Carlota Ciganda in third, while world number one Inbee Park was ninth after four bogeys in a 73 and a one under total.
England’s Charley Hull was the highest placed British player, the world number 25 holed four birdies in a closing 71 for a share of 10th, 11 shots adrift.
Sweden’s Pernilla Lindberg, who beat Park in a play-off to win the first women’s major of the year, the ANA Inspiration in April, finished a distant 15 over.
