His final tournament of the season was in Stockholm for the Stockholm Open. In the round of 32, Baghdatis defeated American Sam Querrey 7–6, 6–1. In the round of 16, Baghdatis shocked in-form Australian Bernard Tomic 7–6, 6–3. He defeated for the second time in 2015 Gilles Muller in the quarterfinals 7–6, 4–6, 6–3. However, Baghdatis's right groin injury again forced him to retire from a match, where he retired in the second set of his semifinal against top seed Tomas Berdych.
