New Zealand’s Valerie Adams crushed her rivals in the women’s shot put in the Diamond League meeting on Wednesday. Adams, the three-time world champion, who became a double Olympic champion after the initial winner in this month’s London Games, Nadezhda Ostapchuk, was disqualified for doping, managed a best of 20.81 metres. The distance was a new record for the meeting — the previous best of 20.63m was set in 2010 by none other than Ostapchuk — with the shot put held a day before the main competition. American Michelle Carter claimed second spot with a best of 19.25m, with Trinidad and Tobago’s Cleopatra Borel completing the podium with 18.66. The result kept Adams well on course for victory in the Diamond League race to earn the title as world number one over the season. The men’s shot put in Zurich was won by Olympic bronze medallist Reese Hoffa, who managed a best of 21.64m, in an American one-two ahead of Ryan Whiting (21.49m).
