KYRGIOS 0-1 LOPEZ: A horrible opening game from Kyrgios as he is broken to 15, netting two woeful shots as Lopez keeps that slice low.

Kyrgios 6-3 6-7 6-3 6-4 Lopez: Fourth match point for Kyrgios, the first on his serve. He gets a time violation as he's preparing to serve - but it doesn't make any difference. He serves it out and he'll face Andy Murray next. Intriguing.

Kyrgios 6-3 6-7 6-3 5-4 Lopez: Tenacious from Feliciano Lopez, saving match points and showing that he can handle the pressure. But can he break the Kyrgios serve?

Kyrgios 6-3 6-7 6-3 5-3 Lopez: Lopez had break point there, but there was a perfect response from Kyrgios - an outrageous ace that stayed in by absolute millimetres. Lopez looks daggers at him when he takes the game with a shot that clips the top of the net.

Kyrgios 6-3 6-7 6-3 4-3 Lopez: Kyrgios challenges Lopez's shot on the final point, then proceeds to proclaim about how he thinks HawkEye is probably wrong. He's doing it in a good-humoured fashion, so there's that.

Kyrgios 6-3 6-7 6-3 4-2 Lopez: A subdued atmosphere now, almost, as Kyrgios holds once again - Lopez isn't putting up the fight he managed yesterday, which is disappointing for anyone who wanted a spectacle.

Kyrgios 6-3 6-7 6-3 3-2 Lopez: Lopez is really cross with himself and the quality of his serve. He's been looking up for help from his team, but what can they do?

Kyrgios 6-3 6-7 6-3 3-1 Lopez: You sometimes overlook it when he's behaving like a naughty child, but Nick Kyrgios is really very good at playing tennis. He's using his backhand particularly well.

Kyrgios 6-3 6-7 6-3 2-1 Lopez: Another fist pump from Kyrgios as he dinks the ball over the net and leaves Lopez entirely flustered.

Kyrgios 6-3 6-7 6-3 1-1 Lopez: Lovely passing shots here, and nifty work approaching the net, simply lovely tennis on show.

Kyrgios 6-3 6-7 6-3 0-1 Lopez: Lopez holds as he opens the fourth set and then promptly goes for a sit-down. Nobody seems quite sure why. The umpire points out his error.

Kyrgios 6-3 6-7 6-3 Lopez: Lopez returns long and Kyrgios moves into a set advantage. There's a quiet, contained fist pump.

Kyrgios 6-3 6-7 5-3 Lopez: There's the break! Kyrgios leaps into the air and his team are on their feet, while Lopez chunters away with rage.

Kyrgios 6-3 6-7 4-3 Lopez: Some marvellous rallying from these two now, fabulous forehands and backhands, and good movement from both.

Kyrgios 6-3 6-7 3-3 Lopez: Lopez levels it up, though, and it's not that the crowd are against him.

Kyrgios 6-3 6-7 3-2 Lopez: "Come on, Nick!" shouts a spectator. The Australian has got plenty of support here.
