As the US Open began, it was announced that Erakovic had been voted onto the WTA Players' Council, replacing Akgul Amanmuradova as the representative of the 51-100 Ranking Category. She would later move to representing the 21+ group, allowing Amanmuradova to regain her seat. She celebrated by recording her first ever singles victory at Flushing Meadows, beating 20th seed and former US and French Open champion Svetlana Kuznetsova in three sets. In the second round, she faced Elena Vesnina, and lost a three-set match in just under two and a half hours. The final score was 7–5, 2–6, 6–4, but Erakovic would have rued her missed opportunities in the first set when Vesnina came from 2–5 down to win five successive games. In the doubles, Erakovic and Parra Santonja were again ranked 17th, just as at Wimbledon (had they won at New Haven, they would have been seeded 15th). They started with a comfortable win against the teenage American wildcards Katerina Stewart (who would progress all the way to the semifinals in the girls' singles) and Louisa Chirico, but the second round match against Muguruza and Suárez Navarro saw the Connecticut Open result reversed, with the Spanish 12th seeds prevailing 6–7, 6–3, 6–3.
