A rare baseline tussle... Djokovic dragging Raonic towards the tape with a drop shot... Djokovic with the lob, but Raonic stretches his 6ft 5in frame to send an overhead beyond the world number one. Raonic is far from convincing and is continuing to cough and splutter at the net, but he holds on to Djokovic's coattails by his fingertips with a hold to 30.
