At the US Open, Erakovic was drawn against second seed Simona Halep in the first round. Serving first, she started with three consecutive backhand unforced errors, dropping both that and her fourth service game as Halep took the first set 6–2 in 32 minutes. After receiving treatment on her troublesome knee during the break between sets, Erakovic was broken in her first two service games to be down 0–3, and retired from the match. Scheduled to play doubles with Watson against Krajicek and Strýcová the following day, she was forced to default.
