Big-serving local hope Sam Groth has been bundled out of the Australian Open in straight sets by No.2 seed Andy Murray.

In his first-ever match on Rod Laver Arena, Groth was dealt a bagel in the first set as a dominant Murray set the tone for the 6-0 6-4 6-1 result.

Murray reeled off the first nine games of the match, breaking Groth’s serve four times, before the big Victorian raised his arms in mock triumph when he held serve in the 10th game to get on the scoreboard.

Groth enjoyed his most competitive period during the second set, breaking Murray’s serve for the only time.

But it didn’t last with the Scot breaking the Newcombe Medallist seven times in the impressive display to extend his perfect record over Australian opponents at ATP, grand slam and Davis Cup level to an extraordinary 18-0.

“It’s nice to play against different game styles … he’s quite different in coming to the net a lot and trying to get forward at every opportunity,” Murray said.

“When he serves well, it’s easy to get impatient because you don’t touch the ball, sometimes for a whole game.

“He didn’t start off the match serving so well, which helped me. But when he picked his serve up in the second set, it became much tougher.”

Murray will face 32nd seed Joao Sousa or Colombian Santiago Giraldo in the third round as he strives to go one better in 2016 after losing four finals at Melbourne Park.
