Rotterdam Open
In February, Dimitrov reached the final of the Rotterdam Open without dropping a set, defeating Yūichi Sugita, Filip Krajinovic, Andrey Rublev, and David Goffin en route, but eventually lost to Roger Federer, who would regain world No. 1 ranking after the tournament. Next, Dimitrov played in Dubai, where he was top seed, but was upset in the first round by Malek Jaziri.
