Has anyone conceded more runs than Abrar Ahmed in their first four Tests?
And who made their highest Test score the latest in their career?
Pakistan's young legspinner Abrar Ahmed has conceded more runs in his first four Tests than any other bowler - 942, including six innings in which he went for more than 100 (in one, he had 5 for 205). He has overtaken an earlier Pakistan spinner, left-armer Abdur Rehman, who conceded 789 runs in his first four Tests, which also included six lots of 100 or more.
Joe Root's performance in the third Test in Karachi last month was indeed the first time he had collected more wickets than runs in a Test, in his 127th match.
It's true that Usman Khawaja improved his highest score in the final Test against South Africa in Sydney last week; before his 195 not out, his best was 174, against New Zealand in Brisbane in 2015-16, which was his first Test century.
There have been four Test innings in which seven different bowlers took a wicket. The first was by England against Australia in Melbourne in 1898-99, in an innings which also included a run out. The other three instances all came in South Africa: by the home side's bowlers against England in Durban in 1922-23; by Australia in Johannesburg in 1966-67; and by New Zealand in Centurion in 2005-06. Only seven bowlers were used each time, apart from the Jo'burg match, where there were eight (the Australian offspinner Tom Veivers failed to strike). There are also two instances of seven in women's Test matches, both by Australia in the current century.
