Back in New Zealand for a short break, Erakovic announced that she would be working with Parra Santonja's coach, Eduardo Nicolás, on a trial basis until the end of the US Open. Clearly refreshed after her time off, Erakovic resumed in the Citi Open in Washington D.C. Playing only in the singles, she defeated Kristyna Pliskova, Shelby Rogers and Bojana Jovanovski on her way to the semifinal, where she was drawn against Kurumi Nara. After taking the first set to love she was able to convert only three further opportunities to break Nara's serve, whilst dropping her own service five times, and eventually lost 6–0, 4–6, 4–6.
