The Irish women's 4x100m relay team won their heat to qualify for tomorrow's final with the second fastest time at the Under-20 World Championships in Finland this afternoon.
Molly Scott, Gina Akpe-Moses, Rhasidat Adeleke and Patience Jumbo-Gula ran 44.27 seconds to beat Italy and France into second and third, with Jamaica not featuring in the qualifying positions.
The USA also failed to qualify for a final, which Ireland must now enter harbouring realistic ambitions of a medal.
Jumbo-Gula came fifth in last week's European Under-18 Championships, while Akpe-Moses came eighth in last night's 100m final.
Earlier in Finland Sommer Lecky jumped 1.84m to progress to the final which takes place on Sunday.
She said: "It was tough out there today because it was really warm, but job done. Final here I come. We'll see what happens in the final. Anything can happen when you're there.
"I felt really relaxed out on the track. I'll recover well for the final now."
Elsewhere, Ciara Neville has qualified for the semi-final of the 200 metres after finishing fourth in her heat in 24.01 seconds.
The semi-finals are at 6pm today Irish time.
Molly Scott qualified for the semi-finals of the 100m hurdles with a third-place finish in her heat.
