Typically, the Serb takes advantage and wins one of his best points of the match thanks in no small part to a sensational baseline dropshot. We are all square still with Djokovic trying to get the crowd behind him to help raise his game.

DJOKOVIC 6-3 4-4 SEPPI. Some impressive first serves pull Djokovic through after Seppi had briefly threatened by taking the first point.
DJOKOVIC 6-3 3-4 SEPPI. That's 14 out of 15 points on a much-improved first serve for Seppi who motors through another hold. If this was against another out of sorts star you'd say Seppi has a big chance - but Djokovic always seems to find a way to the finish line, even in adversity.
DJOKOVIC 6-3 3-3 SEPPI. Both players absolutely cruising on serve. It makes for average viewing for the spectator but could well spring into life when we enter the business-end of the set.

DJOKOVIC 6-3 1-1 SEPPI. Lots of social media and courtside chatter suggesting Djokovic isn't quite right and is suffering a la his pre-gluten free days. If it's creating a level playing field then Seppi didn't get the memo as the world number one saunters to a love hold.

SET! - DJOKOVIC 6-3 SEPPI. A double fault to start shows Djokovic isn't quite himself, a fact exemplified at 40-15 when he inexplicably lets a forehand go that drops in. On another day Seppi may well have taken advantage, but on this occasion he blazes the return of a slow, kick serve long to hand an out of sorts Serbinator the opening set.
BREAK! - DJOKOVIC 5-3 SEPPI. A strange game. Both players almost refusing the opportunities to finish it. Seppi is in the ascendancy at 40-0 but wastes no fewer than four chances to polish it off. It gives Djokovic the scent and despite blowing two break points the Serbinator gets it on the third. The world number one will now serve for the set.
DJOKOVIC 4-3 SEPPI. It's almost 'low key' here. Djokovic struggling to hit any of his high gears but doing enough to stay on serve after that early blip. The Serb will surely warm to the challenge which makes Seppi's failure to consolidate that break all the more disappointing for the 31-year-old Italian.
DJOKOVIC 3-3 SEPPI. The 25th seed puts away a smash at the third attempt at 30-30 on his way to a solid game. Seppi beat Roger Federer in the third round of the Australian Open this year so he is capable of defeating the best... but can he get a first win over Djokovic in 11 attempts here?

BREAK! - DJOKOVIC 2-2 SEPPI. That's why he's won nine Grand Slam titles. Djokovic breaks back immediately to 30. Seppi will be hugely frustrated that he didn't consolidate. Nole won't have too many service games like the last one.
