The Graham brothers represented Scotland together for the first time together in last year’s Men’s Home Internationals in Ireland while they are also in a Scottish Golf Select taking on a Paul Lawrie Select in a new challenge match between amateurs and professionals at Trump International Golf Links in Aberdeen on Monday.
