Mike and Bob Bryan gave the US a 2-1 lead after winning a five-set thriller against Australian captain Lleyton Hewitt and John Peers in the Davis Cup doubles rubber in Melbourne on Saturday.
The result means the Australians will need to win both of Sunday’s singles matches to win the tie.
Hewitt and Davis Cup debutant John Peers pushed the 16-time doubles Grand Slam winners all the way coming from two sets down to lose in five sets 6-3, 6-3, 4-6, 4-6, 6-3.
Hewitt played himself in the doubles after Sam Groth lost against John Isner, struggling in the heat, on the first day one of the tie after the late withdrawal from the tie by an ill Nick Kyrgios.
The Bryan brothers were well on top during the first two sets and looked like they were going to cruise to the win but the Aussies managed to break serve in the third set to get back in the match.
They broke early in the fourth set and that was all that was needed for them to tie the rubber at two sets all.
In the fifth set, the Bryans started well winning the opening eight points to lead 2-0 and eventually went on to win the set and match 6-3 in two hours and 29 minutes.
In Sunday’s matches, Bernard Tomic will face John Isner first on court at Kooyong, with Sam Groth and Jack Sock to follow if needed.
