The two best disabled golfers in the world look set for a showdown on the final day at the inaugural G4D Open, with Brendan Lawlor leading Kipp Popert by a stroke.
Irish golfer Lawlor, ranked second in the world, is on a level 144 after shooting a 74 in the second round.
World number one Popert of England posted a three of 75 to sign for 145 after 36 holes.
Italian Tommaso Perrino and Spaniard Juan Postigo Arce are next in the standings with six wins over par.
Played on the renowned Duchess Course in Woburn, a field of 80 male and female amateur and professional golfers are taking part this week in the new event launched by the R&A.
They compete in athletic classes that cover various standing, intellectual, visual, and sitting categories.
Popert, who was born with a form of cerebral palsy called Spastic Diplegia, has won the G4D Tour five times in 2022-23.
Lawlor, 26, who became the first disabled golfer to compete on the DP World Tour in 2020, has a rare condition called Ellis-van Creveld syndrome, which is characterized by a shorter waist and shorter limbs.
An overall winner will be determined at the end of the three rounds on Friday, along with an opposite-sex winner and a gross prize in each category.
The Golf for the Disabled (G4D) circuit was launched in 2022 and is in its second season.
