what on earth is Warne talking about in the first video regarding the Slider?! palm of the hand facing the batsman is just a square leg break. when he demonstrates it he is clearly showing it as a backspinner by his wrist angle, and then just completely mis-describing it. when he bowls the demonstration delivery hes just dragging the fingers down the back to scramble it. the match delivery they show isnt even a slider, its a leg break that didnt turn.
I was just about to write the same thing. Its just philpotts hard spun leg break. I'm not sure why it should slide on, in theory it should drift to the right the most out of any delivery and turn sharply although not quickly as there is no top spin.The only thing I can think is it gets no grip on super hard test pitches and "slides" on.
I think when the ball is pushed out the front of the hand ( Philpotts exercise of holding the ball out it front of yourself and spinning it back to your chest) it gives the illusion that the fingers are running down the back of the ball but that isn't actually occuring.
Is this just another one of Warnes deceptions. He mentions he and Jenner were working on it so why would Jenner call the round the loop backspinner the slider. If they can't even come to some concensus what hope do we have!!!
Great work with the vids golden arm
