A number of local players from both sides of the border took part in the one-round regional qualifying event, but with just 13 players in the end making it through to local final qualifying from Goswick it was a tough ask, especially in windy conditions.
Porteous will have to wait to see if he will get the opportunity to play on one of four courses near St Andrews in the local final qualifying later this month, having been made 18th reserve following a nine-man playoff for the final two qualifying spots.
With the first group out at 7am and the last at 12.29pm, the results tell their own story, with just one qualifier teeing off before 9.30am. The remaining dozen all came from the later groups, including six from the final six groups.
Although seemingly drawn more favourably in the third to last group, David Ord, representing Goswick, only shot a round of 87, whereas his playing partners both qualified, shooting 68 and 72.
Another disappointed local was Sean Jackson of Magdalene Fields, who shot an 82, while Dunbar member Neil Fenwick hit 79, as did Eyemouth's Daniel Wood.
Former Goswick member Neil Henderson, now representing Glen, shot a creditable 76, finishing just three shots away from those involved in the mass playoff.
Topping the leaderboard however was William Bowe of Workington and Alan Reid of West Lothian, both of whom shot 68s, two shots clear of third place.
Qualifiers will now go on to play at one of Fairmont St Andrews, Scotscraig, Ladybank and Kingsbarns Links for local final qualifying on June 29.
From there, the qualifiers will go on to take part in The Open at St Andrews in mid-July.
Last year, Porteous made it through to local final qualifying for The Open at Turnberry after shooting 71 at Goswick, but Wood, Jackson and Ord missed out, carding rounds of 73, 77, and 84 respectively.
Porteous then missed out on the chance to play in one of the greatest golf tournaments in the world, finishing 12 shots adrift of the final qualifying spot, although he did finish alongside former European Tour player Wade Ormsby.
