The session was a routine afternoon middle practice. De Kock, working through his range against an MI net bowler, was timing the ball cleanly and had hit a series of crisp drives down the ground. The straight six in question came off a length ball that he picked early; the contact was clean and the trajectory took the ball deep over the practice net into the area behind the boundary, where stands of broadcasting equipment, including stationary TV monitors, had been set up earlier in the day.
The ball boy — visible in the broadcast footage as a young man in the standard Wankhede staff polo — saw the ball coming and committed to a leaping catch. The leap was high; the angle was off. He missed the ball by about a foot and a half, and the trailing arm of his leap caught the TV monitor on its stand. The monitor wobbled, tipped, and went down.
The clip is funny because of the symmetry of the failure: the ball, which the ball boy was trying to catch, sailed past his outstretched hand untouched; the TV set, which the ball boy was not trying to catch, took the full force of his attempt. Practice paused. De Kock, watching from the middle, doubled over laughing. The ball boy stood up, brushed himself off, and helped the broadcast staff right the TV. The MI fielding coach, walking over, gave the ball boy what looked from a distance like a small piece of advice and a small piece of consolation.
