Getting the bat above your wrists like that deweights the bat allowing a flow of the bat through the ball.
Especially when combined with playing the ball under your eyes.
@Buzz I'm still unclear. I agree it might be "allowing a flow of the bat through the ball" for vertical bat shots, but I'm just not a fan of the terminology "deweighting". The weight of the bat doesn't change, it's inertia doesn't change, it's centre of gravity doesn't change, so why 'deweighting' or 'unweighting'?
Is 'deweighting' part of the initial batting stance, or is it a new terminology for backswing? If the former, It certainly seems very popular among English batters, and the English Women's team in particular all seem to bat this way.
My biggest problem with this is the simple fact that if your stance has the toe of the bat up around your ears, you have to start playing your shot earlier than you would if you started with that bat at 90 degrees from vertical.
Could you not also 'allow a flow of the bat through the ball' by having the bat 90 degrees from vertical but directly behind you instead of pointing to slips?
If I see anyone batting with the toe of the bat behind their ears I can't help but think that a combination of fast yorkers and slower balls will soon sort them out.
Perhaps I'm just a traditional old fart who needs the 1000 words
Where would I find them, as believe it of not, I am open to change for the better.
