LONDON — Tatyana Lysenko of Russia set an Olympic record to win the hammer throw, an event final that was marred by a technical problem on Friday night.
Lysenko, the former world-record holder who served a two-year doping ban until 2009, set the games record with her first attempt at 77.56 meters and then improved it with her fifth at 78.18. Aksana Miankova set the old mark of 76.34 in Beijing.
Anita Wlodarczyk of Poland earned the silver at 77.60, and the bronze is still in dispute.
China's Zhang Wenxiu was originally ranked third at 76.34 but Betty Heidler of Germany was later elevated to the bronze position when officials remeasured her fifth throw — which didn't initially register at 77.13 due to technical issues — after the final. China has lodged a protest and the medal ceremony has been delayed until Saturday.
