We'll be back tomorrow...

There was some furious racquet smashing earlier, but he's all smiles now, Novak Djokovic, and there are selfies for everyone as he makes his way off the Suzanne-Lenglen court.

And here is Novak Djokovic: "I am pretty tired but happy to have finally got the victory against a clay court specialist.

"I had to draw on a lot of patience. The conditions were difficult - sun and then rain - it made the match very special."

On facing Fernando Verdasco in the next round: "I am going to rest, spend some time with my family, and think about the match tomorrow."

The 13th seed waves goodbye to the crowd as he trots off court, some effort today from Roberto Bautista Agut. He really tested the former world number one.

Djokovic cracks the net with a forehand off the first. Two to go...

Brutal backhand, soft slice. Three match points Novak Djokovic.

Djokovic dictates the point from deep, and Bautista Agut can't keep up with the forehand exchange.

Novak Djokovic to serve for the match.

But the former world number one pops a backhand long - 0-15.

He takes it, and fist pumps in delight.

Djokovic, as if to claim back the drop shot, pulls off his own slice from the baseline that leaves Bautista Agut skidding across the wet clay in vain.

Break point.

The rain is tumbling, but while the macs are out among the crowd the players are still braving it out on the clay.

It doesn't stop Bautista Agut digging into his armoury and pulling out a Djokovic-esque drop shot to make it 30-30.

Oh, Novak. Stop it. The subtlest of crosscourt backhand drop shots falls narrowly over the tape and the Serb holds.

That's better from Djokovic. Steely string play as his racquet almost bends under the duress of that powerful backhand.

But the next one rattles the net - 30-30.

A couple of quickfire errors on either side of the net.

Bautista Agut sees a double-handed backhand drift into the tramlines, before Novak Djokovic pops a forehand long and shrugs in disbelief.

And the baseball-capped Spaniard moves to 40-30. A miscued backhand leaves Djokovic doing his best Incredible Hulk impression, almost tearing off his shirt with one hand.

He's already been through three today.

Bautista Agut holds.

There's the Djokovic scream, eyeballs popping after a forehand goes long...
