I would assume this is to be Old Man Fed's last.

Concerns over the air quality in qualifying which will probably still be an issue for the outside courts here.

Nadal has Dellien.

Federer has Johnson.

Djokovic has Struff.

Federer is due on court at around 02:30 GMT. I'm off this week so will be able to watch it, if I wake up of course.
