Commonwealth Games: Live coverage of Day 4 action from Glasgow

Sam Short has hit the water for the men’s 800m freestyle final.

Having become the first man since Grant Hackett to win the 200m, 400m, 800m and 1500m titles at the Australian Swimming Trials earlier this year, the 400m Commonwealth Games gold medallist will be a firm favourite.

WA’s Iona Anderson was the second-fastest swimmer through to the women’s 50m backstroke semifinal, with the 100m gold medallist posting a time of 27.69sec.

Her compatriot Hannah Fredericks only just scraped through with a 28.50 effort.

What an effort from Rose Davies in the women’s 10,000m final!

In the middle of the pack for much of the race, she stormed to the front and overcame Kenya’s Diana Wanza to become the first Australian female to win the event with a time of 31min39.32sec.

We’re set for a big finish in the women’s 10,000m final.

Australia’s Rose Davies has hit the front with 800m to go!

Back to Scotstoun Stadium, where the women’s 10,000m final is approaching the middle stages.

Australia’s Lauren Ryan and Rose Davies are ninth and 10th respectively.

In the high jump, Ballarat’s Yual Reath has comfortably cleared 2.05m in his first attempt.

An unbelievable Commonwealth Games from Sam Williamson has reached new heights!

The Victorian - who could not even walk due to a serious knee injury 12 months ago - has stormed home to win the men’s 50m breaststroke final, adding another gold medal to the one he won in the 100m.

His blistering finish helped him overcome South Africa’s Michael Houlie and post a time of 26.50sec.

“I still can’t really process everything. Honestly, just trying to put the last 15 months into 26 seconds is an incredible task,” Williamson told Channel Seven.

“I just couldn’t be prouder of the work that I’ve done. From the bottom of my heart, everyone back home that’s supported me ... I can’t thank you enough. This one’s for all of us.

“I thought just getting up on the block each times was going to be an incredible achievement ... to come away with six individual swims under my belt, it’s going to be something I hold onto for a very long time.”

Alex Perkins has secured what is Australia’s fourth gold medal of the night in the women’s 100m butterfly!

The Queenslander added the prize to her women’s 50m butterfly gold medal and two more in relays with a dominant 56.38sec effort.

“Coming into this, I definitely wouldn’t have expected that,” Perkins told Channel Seven.

“I’m just to happy to be here. I’m not necessarily feeling my best, but pushing through. I’m really glad I put that race together.”

Brittany Castelluzzo’s late push for a place on the podium fell only a hundreth of a second short, but her 57.40 was still a fine performance in her first individual international senior final.

Australian teenagers Alyssa Gillespie (1min32.80sec) and Gemma Sellick (1:33.95) certainly did not disgrace themselves in the women’s 100m breaststroke SB8 final.

England’s Brock Whiston won the gold medal in 1:22.05, reeling in a fast start from Uganda’s Husnah Kukundakwe.

Our Australians have missed out on medals in the women’s 100m T38 final.

WA’s Rhiannon Clarke’s time of 12.94sec was good enough for fourth, ahead of Ella Pardy (13.48) and Briseis Brittain (13.50).

Over to the track, where Australia’s Sarah Billings was dominant in her women’s 800m heat, winning comfortably in 2min1.51sec.

And in the women’s shot put F57, Ainsley Hooker and Julie Charlton are battling hard.
