eeeeh just having a bit of a mooch about and stumbled upon this thread!!

Now i'm not wishing to reignite things but for what it's worth i'm with Mox.

He's not saying the ball is hit squarely into the ground, like you would say, with a mallet and fence post.

In the pictures Brian posted you see (as we look at them) the ball being struck and the ball rotating anti clockwise.

How is this rotation possible without the initial movement of the ball being downwards??

It's not a squirt as in tiddly winks, as there is no pressure coming from directly above. But the initial movement of the back of the ball is down, which starts the rotation.
