I totally agree, Stephanie.

Do join us back here on Friday. We'll bring you live text and radio commentary as Britain's Kyle Edmund aims to advance to the fourth round against Nikoloz Basilashvili of Georgia.

But for now, it's goodbye from me.

Stephanie Siu: Federer victorious. Time for lunch.

Now this is interesting.

Roger Federer is asked whether he requested a night match, in order to avoid the brutal temperatures in Melbourne.

"I'm one of 60 guys asking. Do I have more sway? Possibly. But it's not my call. There are other guys they are going to listen to. Maybe it was because of TV? I'm glad I didn't have to go from night to day. I wouldn't mind playing in the day, though. If you're at the top you've got to be able to play in all conditions."

Federer will now play Richard Gasquet in the third round.

"He's got one of the best double-handed backhands in the game - the best in history maybe - I love playing the guy. We've had good matches over the years. He's beaten me on clay and it's a good match up. I expect it to be tough again."

Gasquet has won two of their 18 meetings, FYI.

Roger Federer speaking on court: "I've practiced with him (Struff), and played against him in doubles and singles. You know he can serve 215 or 220 for five hours so that's what you have to be ready for. I had to protect my own serve and get the break with a good defence.

"It wasn't easy. There's an expectation on the underdog but it was a good match and I wish him the best for the season."

Jan-Lennard Struff gets a standing ovation from the crowd. He did himself proud tonight.

One match point is in the bing as Struff finds the corner again.

Super Struff! A lovely backhand into the corner from the German.

But then he looks like he's angled the next point wide. He challenges, it was out.

Three match points to Federer.

Federer wins a battle on the baseline to lead 4-2 and Struff is livid.

The Swiss then bangs down an ace.

Struff volleys into the net as Federer pushes ahead. He recovers with a forehand winner.

Federer powers a forehand down court to move two points ahead but then slams the net carelessly on the next point.

Struff starts with a double fault. Ouch.

Ace. 15-0.

Ace. 30-0

Ace. 40-0

Second serve.

No ace. But he holds anyway in 46 seconds. Tie-break time!

"Yus," yells Jan-Lennard Struff.

From 15-40 down, the German earns an important hold and does it with aplomb.

Once again, Federer serves to stay in the set.

This must be nerve-wracking for Struff. Screw this game up and Federer will serve for the match.

The German misses a close-range volley by dropping it down into the net and he's 15-30.

And then the worse-timed double fault. Two break points for Roger Federer.

Both are fended off with decent winners. We continue from deuce...

Federer wallops a massive ace for 15-0. He's gone big.

Struff forces the ball into the net for 30-0 but then comes in to volley past his opponent to make it 30-15.

Another two big serves from Federer sees him hold with relative ease.

Struff is back at his seat after serving an almighty ace to hold.

He's pumping his fist towards his coaches and looks really, really up for this.

He's going to make the defending champion serve to stay in the set. No pressure.

And now a hold to love for Federer, whose first serve is way too strong.

We're level again. Something's going to have to give.

A hold to love will do nicely for Jan-Lennard Struff.

Very nicely indeed.

"Good stuff, Struffy!

"Keep it up, Struffy!"

I'm surprised it's taken that long to find the German a nickname. He's giving the crowd their money's worth this evening, forcing Federer to produce some of his best to stay in control.

It remains a sticky evening inside Rod Laver Arena, so we might need to be peeled off our plastic seats if this one goes to five sets.
