A year ago, the women's high jump was one of the most hotly contested events, but this season Vlasic has literally raised the bar to be way out on her own.

The 23-year-old from Split has now won 12 of her 13 outdoor competitions this year, and unsurprisingly holds the season's world leading jump of 2.07 metres.

Vlasic went into the event in Osaka as the overwhelming favourite and didn't disappoint, but still said she was shocked she had won after becoming the first Croatian to claim a medal at the 11th world championships.

"I'm just relieved, I wanted it so bad," Vlasic said.

"Now I'm in a state of shock, I don't realise. I'm tired after this. I was the favourite, so had to deal with a lot of pressure.

"This is a championship, you cannot expect to clear every bar in the first attempt," the tall Croatian added.

"It was not easy to beat them."

First major title

Vlasic, twice world junior champion, secured her first major title at senior level before failing with three attempts when trying to set a new world record at 2.10m.

Di Martino was a surprise medallist after suffering a stress fracture in her left foot just three weeks ago.

"Three weeks prior to the world I had a stress fracture in my left foot and had to rest for two whole weeks," the jubilant Italian said.

"But I wanted so much to go to the championships and I am glad I did.

"I feel extraordinarily good, this is amazing. I am rejoicing. 

"When I cleared 2.03 metres I said to myself 'Mamma mia!'"
