London - Joe Root's 190 against South Africa in the first Test at Lord's saw him become the sixth England captain to score a century in his first Test in charge.
But having been 184 not out overnight, his exit on Friday's second day - caught behind off fast bowler Morne Morkel - meant that Graham Dowling's 239 for New Zealand against India at Christchurch in 1968 remained the highest score by any Test captain in their first match in charge.
