Rain disrupted Roger Federer’s start to the Australian Open as he was taken off the court midway through the opening set. The Swiss star was the third match on Rod Laver Arena in the day session.
Federer got off to the perfect start as he broke at the first opportunity to storm into a 3-0 lead.
Johnson was off the mark in the fourth game and Federer held his serve in the fifth for a 4-1 advantage before the rain fell.
The umpire told the supporters inside centre court that play was suspended and the two players made their way back to the changing room.
But the delay is not expected to be any longer than 20 minutes as tournament officials instantly requested the roof be shut.
The ball-kids all attempted to dry the court as they swarmed the arena with towels in hand.
It is thought Federer predicted the rainfall as he practiced on Sunday with the roof shut so he will not feel uncomfortable with the different conditions.
