The 6-3 6-2 3-6 6-7 (10-8) 9-7 victory by the Californian brothers reduced the Americans’ deficit to 2-1, and took the clash to a third and final day.
It also ensured the Bryans – the most successful doubles partnership in the Open era – have never lost after being two sets up.
Murray and Inglot, however, gave the top doubles team in??the world a huge fright, despite falling two sets behind early on.
Murray’s serve was broken four times before the Scot rose to the occasion to??spark home hopes of a comeback to match James Ward’s epic triumph over John??Isner, which put the hosts 2-0 up on Friday, but the twins ultimately kept the visitors in the contest by coming through in the end.
Leon Smith’s side still remain favourites to advance, with world No 5 Andy Murray expected to beat John Isner in the first of Sunday’s reverse singles.
British No 2 James Ward then plays Donald Young in the final rubber on Sunday.
