Good morning, and welcome to our LIVE coverage of Andy Murray v Roberto Bautista Agut at the Australian Open.

BAUTISTA AGUT 6-4 6-4 2-2 MURRAY: Murray's effortful jog back to the baseline is becoming even more so, but his shots are still beautiful, sending his forehand diagonally beyond Bautista Agut, and then trying a tricksy backhand to break the serve! His mum is on her feet, his brother is on his feet, he pumps his fist and that was great.

BAUTISTA AGUT 6-4 6-4 2-1 MURRAY: The comparative speed of Bautista Agut is impressive, and he's forcing Murray to move as much as he can - a sensible tactic, a successful one as he breaks, but rather unpleasant to watch.

BAUTISTA AGUT 6-4 6-4 1-1 MURRAY: You have to respect the Murray fans who are still singing his name in between games. He doesn't look hugely threatening against the Bautista serve, it has to be said; Mats Wilander muses that we aren't seeing the full repertoire of Murray's game, but it's doubtful that anyone really expected to in the circumstances.

BAUTISTA AGUT 6-4 6-4 0-1 MURRAY: An amazing lob from Bautista Agut dips over Murray's head, then another unforced error allows the Spaniard to edge in front.

Murray has won nine previous matches after going two sets down. Just so you know.
