Chinese athlete Gao Xinglong secured China first medal by winning the men's long jump title in the 2016 International Association of Athletics Federations (IAAF) event.

"I have been suffering from a foot injury so I am satisfied with the result. I looked at this meeting as a training session," Gao said after the victory.

Perkovis, who was defeated by Denia Caballero at the 2015 World Championships in Beijing, claimed the women's discus title with a 70.88 throw in her fourth attempt. Aussie athlete Dani Samuels ( 67.77) and Beijing Championships winner Caballero ( 66.17) secured silver and bronze respectively.

"This victory means a lot to me. To open the season with a meeting record and world lead is a great start," an elated Perkovic said. "I have never been in better shape and I am actually a little angry with myself that I didn't throw a little further. Maybe I will do that at Prefontaine IDL."

"For the first time in many years I am healthy without back, knee and ankle problems. I am 100 per cent healthy. I know I have to be in great shape to be in the fight to win gold and deliver my dream of gold at the Rio Olympics," she stated.
