Tomic slammed after crashing out of Wimbledon

Bernard Tomic has joined the Australian exodus from the Wimbledon singles draws with an insipid straight-sets loss to German Mischa Zverev.

Tomic complained of hurting his back in the warm-up but even his victorious opponent was left surprised by the ease of his passage through to the second round.

Australia's former quarter-finalist had thrashed Zverev only last week in Eastbourne, but slumped to a 6-4 6-3 6-4 defeat in just 84 minutes on Tuesday.

"I thought it was going to be a complicated match because I played him a couple days ago in Eastbourne," said Zverev, the tournament's 27th seed.

"I know the way he plays. It's not always easy because it seems like maybe, let's say he's the opposite of, let's say, Rafa (Nadal) on the court with the intensity level between points especially.

"But he knows what to do on the grass court, knows what shots to use.

"He beat me quite easily a few days ago, so I was expecting a very tough match."

Tomic, who reached the fourth round last year for the second time since making the last eight as a teenager in 2011, has a history of back trouble.

The 24-year-old seemed to have jarred it while bending down to attempt an innocuous half-volley.

He dropped serve for the first time soon after to concede the opening set before labouring on for several games until calling for treatment while trailing by a break and 4-3 in the second.

He needed medication but Zverev only needed one more service break in the third set to wrap up the match after just 84 minutes.

The Queenslander can now expect to plummet even further down the rankings from his current standing as the world No.59, having soared to a career-high 17th only last year.

Aussie great Roger Rasheed led the criticism of Tomic's uninspiring performance.

"Bernie, I just don't know where his tennis career is at," Rasheed told Fox Sports.

"Well, I know where it is at, I just don't think he has the capacity he talks about.

"Because there's nothing to suggest there's any desire to be that player.

"Your ranking doesn't lie and your effort does not. Your effort generally rewards you."

Todd Woodbridge said he was worried about where Tomic's game was heading.

"Not a lot of intensity there from Tomic," Woodbridge said in commentary for Channel 7.

"He's in big trouble this year with his ranking, training, fitness and dedication.

"He's already down to 90 and he's potentially going to fall to a position where he's going to have to qualify for the US Open."

Tomic also copped a spray from fans on social media:

The loss continues a disappointing start to Australia's Wimbledon campaign, with Tomic joining Nick Kyrgios, Thanasi Kokkinakis, Jordan Thompson, Daria Gavrilova, John Millman, Andrew Whittington and Ashleigh Barty as first-round casualties.

Qualifier Arina Rodionova is the lone remaining Australian.
