A disappointed Jade Lally has slammed her own poor Diamond League performance in Sweden last week.

Competing in the women's discus at the Stockholm Bauhaus Athletics IAAF meeting, the 29-year-old from Mitcham recorded a best of 55.83m.

It fell well below her current season’s best of 65.10m, and saw her finish fifth at a rain-drench Stockholm Olympic stadium.

Croatia’s current Olympic champion Sandra Perković was a convincing 68.32m winner, Mélina Robert-Michon of France followed with 64.96m and Cuba’s Denia Caballero third in 63.85m.

“I’m fuming with myself because it’s the first time that I’ve struggled in a wet circle,” said Lally.

“You’ve only got three goes and three out of three times it slipped out of my hand, what could I do?

"It’s in the middle of a discus throw and it falls out so you could tell by my flight it’s not right."

She added: “It’s annoying because it looks like I’m in terrible shape, but I have thrown in worse weather at home and hit 60m.

"That’s why I was so keen to throw in the rain, and it looks like I absolutely bottled it which annoys me a lot.”

Lally, who has already booked her place at the Rio Olympics, will be looking to secure her fifth national title at the British trials at Alexander stadium, Birmingham this weekend.

And despite her horrendous showing at the Swedish capital, she insists she is in good form.

“The good thing is I’m in better shape than that so it’s not a case of ‘Oh god I need to go back to the drawing board',” she added.

“I had a really good session before I came here so I’m sure if I got six throws I would have looked much better than Sweden.

"On paper it looked absolutely abysmal."
