Kamwemba and the bowler, Ryan Simbi, led the appeal and it was sent upstairs by on-field officials Donovan Koch and Masudur Rahman where third umpire Nigel Duguid gave it out.
Previously it would have been handled the ball, but that mode of dismissal was combined with obstructed the field in 2017 with MCC saying they were effectively the same thing.
The relevant Law, 37.4, reads: “Either batter is out Obstructing the field if, at any time while the ball is in play and, without the consent of a fielder, he/she uses the bat or any part of his/her person to return the ball to any fielder”.
Unsurprisingly, there was reaction on social media. “Oh get a grip,” Stuart Broad posted on X. “He’s passing a stationary ball back to the fielder? Doing him a favour! Cant give that out.”
Sam Billings retweeted a video of the dismissal, simply adding: “Wow.”
Late last year Mushfiqur Rahim was given out obstructed the field in a Test against New Zealand when he punched a delivery away after defending it down into the crease.
