During the third SA-Aus Test at Cape Town, SPD Smith perhaps became the first Test captain to be sacked in the middle of a match and told to hand over charge. However, he may draw small consolation from setting a minor fielding record.
These records are as of April 1, 2018. The ICC World XI v Aus Test is not counted.
Most catches in an innings by a captain (5 and above):
While wicketkeeper captains Latif and Dhoni have taken 6 catches in an innings, Smith equalled the non-keepers record for captains with 5 catches, along with VY Richardson, SP Fleming, GC Smith and DJG Sammy. There are a few non-captain fielders such as Yajurvindra Singh and AM Rahane who have also taken 5 catches in an innings.
We also look at match fielding performances by captains (6 dismissals and above):
While keeper Dhoni has the record of 9 dismissals (in his last Test), SP Fleming has the record of 7 for non-keeper captains. Smith has taken 6 catches in this Test and in one earlier match. In this case Rahane has the record for 8 catches by a non-keeper, though he was not captaining in that Test.
Finally, we look at overall fielding performances by captains (70 dismissals and above):
While Dhoni has the highest number of dismissals, he is followed by several non-keepers led by GC Smith and SP Fleming who have over a hundred catches. Steve Smith is fairly high up here, sandwiched between MA Taylor and Lara.
