The dream of every left arm (finger) spinner (bowling to a right handed batsman) is to draw him out, beat him in flight, have the ball drift in and then pitch and turn sharply away from him to beat the batsman again for turn and have him stumped. This is exactly what happened today when PP Ohja had Kevin Pietersen stumped . And wasn’t he delighted. I bet even a purist like Bishan Bedi would have chuckled at this.
