Watch: Mitchell Starc's 'Grounded' Catch Triggers Controversy. Here's Why It Was Not Out

As Australia all-rounder Cameron Green got England batter Ben Duckett to hit a bouncer towards the fine third-man area, fielder Mitchell Starc's eyes lit up. Starc seemed to be in absolute control as he grabbed the catch. Upon finishing the catch, the Australia star had a big smile on his face, confident that he did enough to send the England batter packing. But, little did he know of what was awaiting. As Duckett began walking towards the pavillion, he was recalled after the third umpire suggested that Starc's catch wasn't clean.

A huge debate erupted on the field, with Australia skipper Pat Cummins taking up the matter with the on-field umpire, asking why the decision was not out. The suggestion was that Starc, after grabbing the catch, grounded the ball. Since he wasn't in control of the catch entirely, the decision had to be given in the favour of the batter.

A bemused Australian team looked disappointed while the debate over the catch erupted on social media too.

In relation to the below incident, Law 33.3 clearly states that a catch is only completed when the fielder has "complete control over the ball and his/her own movement."See here for full clarification:
