Canberra sprint queen Melissa Breen has run her fastest time since breaking a 20-year Australian record, sending a message to Athletics Australia after she was overlooked for funding.

Back to her explosive best, Breen stormed to a win the 100 metres at the Oda Memorial Meet in Hiroshima on Tuesday, clocking 11.28 seconds in the final.

She also clocked a heat time of 11.22 seconds, just 0.11 seconds slower than the Australian record she set in February.

It was Breen's second fastest time outside Australia and she has now run five Commonwealth Games A-qualifying times in the past three months.

"I'm very happy. I am glad the final was a legal windand I felt like I executed it better than the heat," Breen said.

"I still have some things to iron out with my blocks but we have recently been playing around with some different focus areas and that will take a bit of adjusting and refinement."

Breen broke Melinda Gainsford-Taylor's 20-year Australian record at a meet in Canberra in a time which would have won her a gold medal at the 2010 Commonwealth Games.

But her progression was rewarded with just $4000 from the sport's peak body, a third of the funding she had been expected to get.

Athletics officials want Breen to prove she can be consistently fast and get closer to her Australian record of 11.11 seconds.

The 23-year-old sent a reminder to her doubters on Tuesday, cruising to victory as she continues her Commonwealth Games preparation.

Breen is on a two-week trip to Japan where she is competing at four meets and hopes to lower her national record.

Breen has raced in Japan for the past seven years and will race at Shizuoka on May 3, Mito on May 5 and Tokyo on May 10.

Breen will compete in the 200 metre event at Shizuoka.

“I missed some work and races through February and March being safe and looking after my body after the national record so running two 200m in Shizuoka will make for a good training day.”
