Capacity at the first ever sell-out Open Championship has been expanded to meet demand for the tournament's return to Northern Ireland.
Championship day tickets for Royal Portrush Golf Club sold out last autumn.
The R&A has now announced the release of thousands of extra tickets for July's showpiece on the Causeway Coast.
The capacity for each championship day is being increased from 40,000 to 43,750 - a move that will bring the overall number of tickets for the event, including practice days, to 215,000.
The new tickets will go on sale on April 15, with tickets for practice days still available.
R&A chief executive Martin Slumbers said: "From the moment tickets and hospitality packages went on sale last year it was clear that there was huge demand from fans to attend this historic occasion.
"We have been working closely with the government agencies, our advisers and contractors to assess whether we could accommodate some more fans on each day of the Championship and have decided that we can do so without impacting on the outstanding spectator experience we provide.
"We are delighted to be able to offer more fans the opportunity to book their place at Royal Portrush by releasing additional tickets and introducing two new hospitality experiences, which will enhance even further what will be a fantastic atmosphere in July."
The only other time the Open was staged in Northern Ireland was in 1951, when Royal Portrush also played host.
Tourism NI chief executive John McGrillen added: "We very much welcome this announcement and it is evident from the Championship's record-breaking sell-out of tickets to date that there is great excitement for its return to Northern Ireland for the first time in almost 70 years.
"This increase in capacity will give even more people an opportunity to visit our shores and with tens of thousands of spectators and visitors from across the world expected to be in attendance, it is shaping up to be the biggest event ever held here
"We're working with our partners at the R&A, the Council and many other agencies, to deliver a fantastic event in July and we can't wait to show our local, national and international visitors the best of NI and the legacy it will leave for golf, sport and tourism here."
