Commonwealth Games 2022 day four wrap: Gold ripped from Aussie weightlifter; Kyle Chalmers wins 100m freestyle gold; Cody Simpson qualifies for 100m butterfly final

Thanks for joining our live coverage on another big day at the Commonwealth Games for Australia.

Wide World of Sports will be back with more from Birmingham at 6pm (AEST).

Australia has continued its domination at the Commonwealth Games overnight with nine gold medals, highlighted by a big win for Kyle Chalmers in the pool.

Kaylee McKeown, Emma McKeon and Matt Levy all won gold medals, while Australians Elijah Winnington, Zac Incerti, Mack Horton and Flynn Southam ranked first place in the 4x200m freestyle relay.

Australia also won gold medals in judo, lawn bowls, cycling and gymnastics.

MEDAL TALLY AFTER DAY 4

1. Australia 71 (31 gold, 20 silver, 20 bronze)

2. England 54 (21, 22, 11)

3. New Zealand 24 (13, 7, 4)

4. Canada 33(,6 11, 16)

5. South Africa 12 (5, 3, 4)

6. India 9 (3, 3, 3)

7. Scotland 23 (2, 8, 13)

8. Malaysia 6 (2, 2, 2)

9. Nigeria 4 (2, 0, 2)

Emma McKeon won her second gold medal of the day and the 12th of her career in the women's 50m butterfly final, in a time of 25.90.

With half a second separating the entire field, McKeon just held on after a fight back from fellow Australian Holly Barratt, who tied for second place with South African Erin Gallagher.

Fellow Aussie Alex Perkins finished fifth.

Cody Simpson is through to the final of the 100m butterfly, joining countryman Matt Temple in the decider after qualifying fifth-fastest for the race.

Simpson looked in danger of missing a spot on the second lap in his semi-final but he managed to snare third with a time of 52.16 seconds.

"Pretty wild, pretty special. That was my goal to make sure I got into the final – just relieved that I am," he said.

"I will probably go back and watch it right away and make sure there are things I can find [to improve]."

The singer has a personal best of 51.79 in the 100m butterfly, achieved in the heats at the Australian trials in May.

That time would have seen Simpson qualify in third place for the final in Birmingham.

Australian Kaylee McKeown had to settle for silver to go with the gold she won earlier after Canadian teenager Summer McIntosh proved she's on another level in the 200m individual medley.

The 15-year-old hit the wall at 2:08:70 under a second quicker than McKeown, who got there in 2:09:52.

A strong breaststroke leg gave McKeown a fighting chance and put her into medal contention but McIntosh maintained and won in world junior record time, securing her second gold medal of the Commonwealth Games.

McIntosh has already been hailed a "generational talent" and is tipped for big things at Paris 2024.

An emotional Kyle Chalmers says even a Commonwealth Games gold medal is tough to celebrate after the week he's been through.

"It's special, special to win. But unfortunately, I think it's hard to enjoy the moment when all that's happened has gone on," he said.

"It makes it a very, very challenging time. I'm grateful that I was able to block it out enough to stand up and win tonight. 

"But I just hope that no one — I hope this is a learning point for everyone. And, you know, where no one else has to go through what I've had to go through the last couple of days. It's been very challenging."

Chalmers said he knew his soldier brother was watching the race, saying his "best mate" was the last thought to run through his head before jumping off the blocks.

He brought a finger to his lips after the race as swimming legend and commentator Ian Thorpe described the swim as a performance designed to "silence his critics".

The swimmer said he thought about not going on but decided that would just let "the media win".

An emotionally exhausted Chalmers was asked about his future aspirations, but the Aussie said he could not guarantee he'll compete at the 2024 Olympics in Paris. The swim star revealed he almost burst into tears when speaking to his coach before the race, with the intense media speculation set to cloud his future if it continues.

"I definitely want to. That's been my dream to win in Paris," he said. "But if I have to keep going through a similar thing I won't last until Paris, I know that. It's too challenging and not something I swim for.

"I know I stand here bravely, but this has really set me back a lot. I really don't know what's next for me. Right now I'm on a high of racing, but I'm sure tomorrow when I wake up or at the end of the week when I get my flight home there'll be plenty of different emotions that go through my head, but if it is the pool I think I'll go back (to the same training set-up)."

Kaylee McKeown has broken a Commonwealth Games record to claim the 100m-200m backstroke double.

Having already bagged the 100m title, the Olympic champion was led at the first change by compatriot Minna Atherton but quickly hauled her in and pulled away from the rest of the field.

Canada's Kylie Masse finished second and Scotland's Katie Shanahan claimed bronze as Atherton faded late to just miss the podium.

McKeown now has a rapid-fire turnaround before the individual medley.

Australian swimming champion Kyle Chalmers has bagged another gold, in the 100m freestyle.

In an emotional week, the swimmer led the field at the turn and powered home to win in emphatic fashion in 47.51 seconds from England's Tom Dean and Scotland's Duncan Scott. 

Aussie William Yang finished sixth and Zac Incerti came eighth.

It's gold again for Australia, this time on the judo mat.

Tinka Easton had to come from behind to beat Canada's Kelly Deguchi in the women's 52kg final.

She didn't seal the match until golden score but the look on her face proved it was worth the wait.

After the bout, Easton said she "had my eyes on gold" coming into the Games but felt it almost slipping away at one point.

"I just reset and went back to my game plan," she said.

"I got a bit frantic in the middle, so I went back to focusing on the process and the gripping plan."

Easton wasn't the only judo success for the Aussies overnight, with brothers Joshua and Nathan Katz both claiming bronze medals.

Nathan's third-place-playoff win in the 66kg division was particularly dramatic, coming from behind with a big throw to beat India's Jasleen Singh Saini.

It's a double dose of green and gold for Ellen Ryan, who's just added to Australia's gold medal tally on the bowling green.

The Sydneysider got off to a horror start against Lucy Beere of Guernsey, losing the first three ends and not notching a convincing win until the ninth.

But the 25-year-old proved too strong in the end, keeping her opponent almost scoreless in the final nine ends and winning the last three in a row.
