Wimbledon Haikus?

What's this that I read at the Wimbledon website... Wimbledon Haikus? It's weird but also quite witty but not so funny. Read them below:

The shiny new roof,
still unused in good weather.
Punters pray for rain.

English players drop
from the board like chestnut leaves.
Scots stay evergreen.

Nightfall. Not a trace
of today’s blood sweat and tears.
The sprinklers switch on.

Thump! Pat Cash tumbles
over the net and Boris
becomes his echo.

"Out!" Yells the line judge.
"You cannot be serious!"
Hawkeye says "Bad luck".

Remember, red cross
on white means First Aid. White cross
on red: Federer!

Easy on the Pimms.
Remember, beer before wine.
Avoid mixed doubles.

A lady in red
skin paler than passing clouds.
Strawberries and cream.

Urrrgh! The starlet's grunt
fails to phase her opponent.
Ball boy’s heart flutters.
