Nick Kyrgios accuses officials of fixing match in Fever-Tree Championships

The outspoken Australian moaned, groaned and swore his way through two matches, picking up a code violation in each, and exited the tournament with a predictable rant at the officials.

During his first-round win against Roberto Carballes Baena, Kyrgios launched an expletive-ridden rant at umpire Fergus Murphy after missing a set point, claiming the Spaniard had double-faulted.

He said: "Bro you are taking the f****** p*** mate? The ball was this far out, no joke. No joke. What are you doing? It's so far long. What are you doing?"

In bizarre scenes he later turned to Murphy and said: "Like, your hat looks ridiculous, also. It's not even sunny."

The 24-year-old also accused a line judge of "rigging" the match, while at one point admonished himself for "playing FIFA until 3am".

As if that were not enough, Kyrgios faced a second match due to rain delays earlier in the week and was beaten in three sets by Canada's Felix Auger-Aliassime.

He walked onto court muttering that he had "zero chance of winning", but he should have, only to tank in the final game, playing a ridiculous 'tweener' to offer up match point in the deciding set.

It was a relatively tame affair by comparison, although Kyrgios still managed to collect a code violation after smacking a ball right out of Queen's Club.

He threw in a smattering of underarm serves, overruled one line call in favour of his opponent and ranted at a camerawoman for taking his photo while he blew his nose.

Afterwards Kyrgios said: "I thought some of the calls were outrageous today. It shouldn't have to come down to me and Felix giving each other points.

"He gave me a point at a pretty crucial time, and I gave him a point at a pretty crucial time.

"I just don't think, at this level of sport, that we should have line judges and umpires that aren't making the right decisions.

And I know what happens. Nothing happens. They get a little slap on the wrist. You know, they don't get any warning or fine or anything for their mistakes.

"So what's the difference? For me doing a code violation, why can't they get fined for having a terrible day in the chair?

"Like, there's hundreds of thousands of dollars on the line. It's not a joke. They just think it's a joke because nothing happens to them after the match. They don't get any investigation or anything.

"I think it's ridiculous. Like, why not have another umpire ready to come in if that guy's having a terrible day?

"I don't understand. I have to pay the fines for it. The calls are horrendous, but I get fined and he gets nothing."

Elsewhere, defending champion Marin Cilic was a surprise second-round casualty, losing in straight sets to Queen's Club debutant Diego Schwartzman.

Argentinian Schwartzman, 26, secured early breaks in both sets to wrap up a 6-4 6-4 victory, only his third career win on grass.

British interest, in the singles at least, came to an end when Kyle Edmund succumbed to top seed Stefanos Tsitsipas.

The British number one was a set down and 3-3 in the second when rain caused the first-round match to be suspended on Wednesday evening.

Edmund gamely fended off six match points but Tsitsipas got lucky with the seventh, Hawk Eye showing his backhand had just clipped the line to secure a 6-3 7-5 win.

Greek youngster Tsitsipas was back on court a couple of hours later and had to call on all his reserves of energy to come through a three-setter.

Jeremy Chardy, a semi-finalist last year, took the first set but Tsitsipas came back to triumph 4-6 7-6 (0) 7-6 (4).

Second seed Kevin Anderson, who beat Britain's Cameron Norrie in round one, was sent packing in three sets by France's Gilles Simon.

The big-serving South African, last year's Wimbledon runner-up, has missed a chunk of the season through injury and it told as Simon ran out a 6-1 4-6 6-4 winner.

French qualifier Nicolas Mahut was given a warning after hitting a ball girl in the face with a stray serve during his second-round win over Stan Wawrinka.

Mahut, having just lost a service game, sent a practice serve back over the net, inadvertently hitting the young girl.

She was reduced to tears and, after being comforted by Wawrinka, had to leave the court.

Mahut received a code violation for unsportsmanlike conduct from umpire Mohamed Lahyani, but BBC TV commentator John Lloyd felt the punishment was unnecessary, saying: "It was a complete accident. I don't think you really need to give a warning for that. I hope he doesn't get a fine."

It was the second time Mahut has accounted for a ball girl in two matches, having accidentally slid into another youngster during his first-round win over Frances Tiafoe.

Mahut won the match 3-6 7-5 7-6 (2) to set up an all-French quarter-final with Simon.
