Novak Djokovic beat Marin Cilic, 6-4, 6-2, during Serbia’s semifinal tie against Croatia at the Davis Cup Finals on Friday, not only improving to 18-2 in his head-to-head against the 2014 US Open champion and former No. 3, but also extending his Davis Cup singles winning streak to 19 matches in a row.

Djokovic’s 19 Davis Cup singles wins in a row actually ties him for fifth-longest singles winning streak in Davis Cup history. Only four players have gotten to 20 in a row.

Djokovic is now 19-0 in Davis Cup singles matches over the last decade, and he’s also won 26 of his last 27 Davis Cup singles matches since the start of 2010, his only loss in the event over the last 12 seasons coming in the Davis Cup semifinals in 2011, where he had to retire against Juan Martin del Potro due to a back injury.

He’s now 38-7 overall in his career in Davis Cup singles matches.

Serbia ended up losing the semifinal tie to Croatia, 2-1.
