Jarmillia Murphy-Knight, who made her international debut, has made the semi-finals of the 400m after finishing the race strong.

The 18-year-old finished fourth with a personal best of 59.19 seconds and qualified as one of the six fastest non-automatic qualifiers.

Another debutant and teammate Annamaria Leszczynska was unable to hold her pace down the final 100m and finished sixth in her heat in a solid 59.94, missing out on a place in the semis.

Australian running rising star Riley Day started her Championships in fine form for the 100m with a time of 11.77 seconds to automatically qualify for the semi-finals later this afternoon.

Mia Gross placed fifth in her heat with a time of 11.80 seconds and had a nervous wait to see if she was one of the four fastest non-automatic qualifiers.

Unfortunately, she was knocked out in the final heat to miss by one spot, and just 0.03 seconds.

In the women’s 3000m Australians Amelia Mazza-Downie and Lara Crouch finished in the top 10.

Crouch and Mazza-Downie were part of the main pack with eventual gold and silver medalist Japanese duo Nozomi Tanaka and Yuna Wada.

Mazza-Downie finished in sixth place (9:09.19) while Crouch was tenth (9:16.28) as they both ran personal best.

Also on the track was Ella Connolly, who took the win in semi-final three of the 400m, in a season’s best 52.78 seconds and pipped Kenyan Mary Moraa on the line by 0.2 seconds.
