The 42nd-ranked Canadian clinches the opener with her third break of serve to take it 6-1 against the American.

That took her just 27 minutes. Speedy.

That's because Arthur Rinderknech holds to love in the game, courtesy of some big serving.

The 27-year-old Frenchman is one game away from taking the first set and the home fans are enjoying every second of it so far.

I'm living for the random trumpeter who's playing a little melody after every game.

Feels very England football supporters at a major tournament.

This is some atmosphere on Court Suzanne Lenglen. Forget the players, the crowd will do well to keep this up for (at least) three sets!

Taylor Fritz does his best to silence them. He earns four break back points but Arthur Rinderknech saves the lot and eventually holds.

That brings another mighty cheer and the volume level is raised even further as the Frenchman breaks again. Fritz is usually so calm but he looks rattled early on here.

Ideal start. Zverev is covering every inch of the court as he sprints forward to the net and breaks with a clinical drop shot.

Alex Molcan will serve first.

Just like last night, Philippe Chatrier isn't exactly full.

"Good match, good match," declares the umpire.

The players get their warm-up under way.
