The ICC should investigate the decision process behind this decision, offer an explanation, or stand the video umpire down. There appeared not to be a shred of evidence - audio, deviation, or hot spot to see Agar be given out - truly baffling.
In the 1st test? what what I saw on Sky Sports there was sound and a slight but non the less small hotspot. Smallest edge I've ever seen but along with the sound he looked out to me.
