Athletics: Adams finds form to beat arch-rival

New Zealand's Valerie Adams unleashed a season's best throw at the Continental Cup athletics meet in Split, Croatia this morning (NZT) to beat Belarussian shotput arch rival Nadzeya Ostapchuk for the first time in nine encounters this year.

Ostapchuk was on a 12-meet winning streak coming into Split to arguably be the most dominant female athlete on the athletics circuit in 2010.

But world and Olympic champion Adams, who set her Oceania record of 21.07m in her final competition of 2009, once again left her best throw of the year until September.

Adams made her intentions clear when she opened with a season's best of 20.70m.

The New Zealander increased the pressure with another season's best of 20.86m -- a mark Ostapchuk has only once surpassed outdoors this year - and followed it with consistent efforts of 20.76m and 20.56m.

The Belarussian managed a best of 20.18m in round three. before fouling out with her final throw. China's Gong Lijiao was third in 20.13m.

Adams' longest throw was the second best ever at an IAAF World Cup and was within 12cm of the oldest women's record in World Cup records set in 1979 by Ilona Briesenick.

Adams said showing patience with her new speed-based technique was starting to pay off.

"Just having the patience with each throw will bring a lot on," said Adams, who has been working recently with Swiss shot put legend Werner Gunthor.

"Today was a good flow, I felt really good, felt strong, felt fast and it was just bound to happen, I knew that I had the potential of throwing 20.50m, but it was just a matter of doing it.

"I was very ecstatic; I was able to pull through all four throws over 20.50m and could have won it on all four. I've got so much more to improve on and looking forward to next time I'm out there."

Earlier, in the women's 1500m, New Zealand's Niki Hamblin was sixth behind French winner Hind Dehiba in four minutes 22.45 seconds.

It came 24 hours after Hamblin ran her best time over 800m, where she placed seventh in 1min 59.66sec, about 1.5sec outside Toni Hodgkinson's national record.

New Zealander Adrian Blincoe was sixth in the men's 3000m in 7min 57.67sec.
