After a Controversial Run, Australia's Tomic and Kyrgios Crash Out of Wimbledon

Albeit in vastly differing circumstances, Nick Kyrgios and Bernard Tomic have both lost their fourth round encounters, putting paid to Australian hopes at this year's Wimbledon.

The first Aussie duo to reach the second week at SW19 in a dozen years, a lackluster Kyrgios was taught a lesson by Britain's Andy Murray while Tomic went down in five hard-fought sets to tournament surprise packet, Frenchman Lucas Pouille.

The win gives Murray the "Kyrgios Slam" having now ousted the uber-talented 21-year-old in all four Grand Slams.

However, it wasn't the superlative efforts of the second seed creating headlines but again Kyrgios, who put in what he described as a "soft" effort during his 7-5 6-1 6-4 loss before going on to once again question his dedication to the sport.

"I obviously like playing the game," he said. "But, yeah, I don't know whether… I don't really know."

After a relatively competitive opening stanza, Kyrgios found himself staring down the barrel of three set points at 5-6 0-40. He managed to claw back the first two with a couple of big serves but after dumping a forehand volley into the net to give Murray the first set, he dropped his head and completely disappeared mentally for the rest of the match.

Kyrgios summed up the collective feeling afterwards, saying that "it was a good first set (but) the rest of the match was pretty pathetic".

Three-time Wimbledon champion John McEnroe was quick to jump in.

"It's a damn shame when he does this," he said. "I hope he will see the writing on the wall before it gets in his head and becomes chronic and irreparable."

Earlier, Tomic was edged out 6-4 4-6 3-6 6-4 10-8 by Pouille after holding a 4-2 advantage in the final set.

"I felt like this was a big opportunity for me," he said of his blown chance to at least replicate his 2011 quarterfinal appearance. "(But) I managed to play a player that was doing the right thing and playing the right way to win today.

"He was playing the match of his life."

Despite being accused of lack of effort himself in the past, Tomic spoke in direct contrast to his compatriot Kyrgios on Monday, saying these type of matches can go either way, but it was just "important to compete".

Australia still has some interest remaining in men's doubles, with Sam Groth and his Swedish partner Robert Lindstedt taking on top-seeded French pair Nicolas Mahut and Pierre-Hugues Herbert for the right to play Davis Cup team member John Peers and Finland's Henri Kontinen, the tenth seeds, in a quarterfinal.

In the women's event, Australians Samantha Stosur and Daria Gavrilova were both eliminated the second round.
