I watched that 22 seconds multiple times. Thank you very much for posting it.
Zim Commentator first was stunned to see the hit. He didn't start to speak till the ball reached the ropes. He was astonished, shocked and out of words. Back to his senses with Mic on mouth:
"Nearly killed him" (pause) still searching for words.
"Wanna tell you (pause) he has hit that as hard as anyone who has hit a cricket ball
" he is back to reality and understands the fierceness of the shot. Now watching replay he is adding to his comments.
"Chamu Chibabha didn't have a chance to move. He didn't move his head and I reckon it missed by couple of centimeters" (pause) lost of words again.
Atahar got the opening, "What about the umpire??? Went like a Rocket."
