Croatia head to the World Group play-offs in September, looking to make an instant return to the competition's top tier, after a dramatic win over Poland in Warsaw. Marin Cilic eased to victory in the opening singles rubber, but a major shock was in store in the second rubber, as 17-year-old Borna Coric defeated Polish No. 1 and 2013 Wimbledon semifinalist Jerzy Janowicz in five sets. Mariusz Fyrstenberg and Marcin Matkowski kept Poland in the tie, although were forced to work very hard for the victory, winning in five sets against Marin Draganja and Mate Pavic. The drama continued in the reverse singles as Janowicz let a two set lead slip as Cilic won to put Croatia into the play-offs.
