On 5 June 1994, she set a new world record with 67.34 metres. Unfortunately, this happened before the IAAF recognized world records in hammer throw for women, so when Mihaela Melinte threw 66.86 metres on 4 March 1995 she set the first official world record.[2] In June the same year Olga Kuzenkova improved it to 68.14 metres. Sudak later improved her personal best to 69.80 metres, well behind Tatyana Lysenko who had set a new world record of 77.06 metres a week earlier.
She then became a citizen of Turkey. She competed at the 2007 World Championships and the 2008 Olympic Games without reaching the finals. Her personal best throw was improved to 70.74 metres, in July 2008 in Minsk.
