Top seeds Bob and Mike Bryan have been knocked out of the men's doubles at the Australian Open after losing to Eric Butorac and Raven Klaasen in straight sets.
The 7-6(9) 6-4 defeat means that the 15-time Grand Slam-winning team fail to progress beyond round three in Melbourne for the first time in 11 years.
American Butorac and South African Klaasen won 68 points during the 78-minute match, while the Bryan brothers won 66.
The reward for beating the twins is a clash with 12 seeds Treat Huey and Dominic Inglot.
