On paper, Andy Murray's fourth round meeting with Frenchman Stephane Robert appears to be one of his easiest Grand Slam matches of recent years.
Not only is he the lowest-ranked player left in the men's singles, he also made it in the tournament as a 'lucky loser'.
Despite being beaten in the third qualifying round by Germany's Michael Berrer, the 33-year-old earned a reprieve when another German - Philipp Kohlschreiber -pulled out because of injury.
Since then, Robert has conceded just a single set - and that was a tie-break - en route to winning three straight matches and into the last 16.
The world No 119 had never previously gone beyond the second round of a Grand Slam event but will now face Murray at the Hisense Arena on Monday.
Just three weeks ago Robert was beaten by British No 3 James Ward in Brisbane and Murray said of his next opponent: "I know him a little bit from when I was coming through the Futures and Challengers circuits. Obviously that was quite a while ago now.
"But it's good to see. He's 33 and it could be easy to stop playing if you're not in the top hundred or necessarily making a great living.
"But it does show if you stick at it, you're professional, and when your chance comes you take it, you can do great things.
"Great for him. Good for tennis as well. He's played six matches already so he'll be match-tight, that's for sure."
And Robert did not know he had been included in the draw until 10 minutes before he played his first match against Aljaz Bedene.
He stressed: "I opened a bank account in US dollars and I was filling in a paper for the ATP.
"So when they called me I put this straight in my bag and then I went to see the referee.
"He told me, 'Okay, you're ready to play? Court 7. Go'."
He is now guaranteed a large cheque but Robert added: "I'm not checking the prize money. I'm not checking the rankings or points, because when I do this, then I'm losing."
