Murray stuns Rod Laver Arena with woeful serve

A stunned silence fell over the crowd after Andy Murray landed a second serve halfway into the wrong service box, summing up his loss to Mischa Zverev.

The World No.1 was desperately trying to hang on in the fourth set against Zverev when he produced the truly horrible shank.

"Wow!" Jim Courier said in commentary as the crowd watched on in amazement.

Murray was well off the boil in the shock loss, struggling with his serve all game.

Courier was among those surprised by Murray's failure to bring the match back under control during the fourth set.

"He's a passenger in these points right now," Courier said.

"He's in the second chair. This guy (Zverev) is driving."

It is the first time in more than a decade that Murray has been defeated at a grand slam by someone ranked as lowly as Zverev.

"It just wasn't meant to be," the Scot said.

"He served very well when he needed to, especially when he was behind in games. He deserved to win.

"He came back from all of the mistakes that he made, kept coming up with great shots. There's not too much you can do about that. It was obviously disappointing to lose. But he did some good stuff out there."
