Andy Murray speaking on court: "Grigor Dimitrov has been playing well in the last few weeks. He is tough player who moves well and is very talented. Hopefully I will play a good match because i will need to if I am to get through."
BBC Radio 5 live sports extra
Davis Cup team-mate Dominic Inglot on 5 live sports extra: "You love winning matches when you are not playing well. And if you can win when you are up against a little resistance that can be good too. You can call on those moments when you come up against tough players later. But obviously he'll need to improve.
Murray 7-6 (7-4) 5-7 6-2 6-3 Lorenzi
Paolo Lorenzi departs the scene to cheers and selfies.
He has had a stellar tournament. The best work week of his life.
Murray 7-6 (7-4) 5-7 6-2 6-3 Lorenzi
Paolo Lorenzi's frenetic, frenzied fight comes to an end as he bumps a backhand long.
Next up for Andy Murray is Bulgarian glamourpuss Grigor Dimitrov - the man who ended the defence of his Wimbledon title in 2014.
Murray 7-6 (7-4) 5-7 6-2 5-3 *Lorenzi
Andy Murray rattles through the game to love.

*Murray 7-6 (7-4) 5-7 6-2 4-2 *Lorenzi
Death, taxes, the tide - Paolo Lorenzi just keeps coming at Andy Murray.

Murray is being kept honest right up the straight.
*Murray 7-6 (7-4) 5-7 6-2 3-2 Lorenzi
Paolo Lorenzi is a player without any obvious weapons. No siege gun serve, no sledgehammer groundstrokes, not an especially silken touch at the net, but his all-round game is solid and his application is unstintingly excellent.
With only his second ace of the match, he buys a ticket back to his courtside seat.
Murray 7-6 (7-4) 5-7 6-2 3-1 *Lorenzi
With the clock ticking close to three hours, Andy Murray can finally sniff the finishline.
This will not be a match he looks back on fondly. Paolo Lorenzi has befuddled him with his energy and while Murray's own form has frustrated him.
