She competed for the Brazilian team in the
4 × 100 metres relay at the
2012 Summer Olympics; the team set a South American record with a time of 42.55 in Round 1, then placed seventh in the final with a time of 42.91. At the
2013 World Championships in
Moscow, the team composed by
Ana Cláudia Lemos,
Evelyn dos Santos, Franciela Krasucki and
Rosângela Santos broke the South American record in the semifinals of the women's 4x100m metres relay, with a time of 42.29 seconds. But, without official explanation, the CBAT (Brazilian Athletics Confederation) held an athlete change to the final, putting
Vanda Gomes instead of
Rosângela Santos, to close the race. In the final, Brazil came second, almost tied with Jamaica and with great possibility to win the silver medal, and knock the South American record when, at the last exchange between Krasucki and Vanda, the baton fell eliminating the Brazilian team. In February 2014, in
São Caetano do Sul, she twice broke the South American record in the
60 metres, with a time of 7.23 seconds in the semifinals, and 7.19 in the final. The previous South American record holder was Esmeralda Garcia Freitas, established on March 13, 1981, in
Pocatello, United States, with a time of 7.26. ==Personal life==
