Grigor Dimitrov reaches Cincinnati Masters semifinals

After an impressive win against the US player Steve Johnson by 7:6, 6:2, Bulgaria's Dimitrov will go on to the Cincinnati semifinals.

The only certain thing about the next match is that he will be playing againsta a Croatian - the winner of the other quarterfinal - either Marin Cilic or Borna Coric. 

Both contenders are equally respectable, Cilic managed to defat Dimitrov at the Rio Olympics, while the 19-year old Coric threw Rafael NAdal out of the race in Cincinnati.
