This unusual double was completed when Mudassar Nazar and Shoaib Mohammad opened the innings for Pakistan against New Zealand in Karachi in 1984-85. Their fathers, Nazar Mohammad and Hanif Mohammad, opened in Pakistan's inaugural Test, in Delhi against India in 1952-53.
Essex's Australian fast bowler Peter Siddle currently lies seventh on this list, from which I suppose he may yet escape. Before the round of Championship matches that started last Thursday, he had taken 645 first-class wickets, with a best match return of 9 for 77, for Victoria against South Australia in Melbourne in 2011-12. Ahead of him lay Lancashire's Paul Allott (652 wickets), Bertie Buse of Somerset (657), the three-county seamer David Masters (672), Warwickshire's Freddie Calthorpe (782), Hampshire's Mike Taylor (830) and the overall leader, Glamorgan and England allrounder Allan Watkins, who took 833 wickets without the aid of a ten-for. Garry Sobers finished with 1043 wickets in first-class cricket with just one haul of ten - 11 for 156 for Nottinghamshire against Kent in Dover in 1968.
Babar Azam is one of five men who won their first four Tests in charge, following Englishmen WG Grace, Lord Hawke and Brian Close, South Africa's Ali Bacher (who won all four Tests he captained), and MS Dhoni of India. But two others are some way ahead: Warwick Armstrong won the first eight Tests in which he captained Australia, while later in the 1920s, England's Percy Chapman went one better, winning his first nine matches in charge.
Three men have managed a run of ten successive first-class scores of 50 or over. The first to do it was the Lancashire and England batter Ernest Tyldesley, in 1926. His sequence included seven centuries, and ended with an innings of 81 after being recalled for the fourth Test against Australia at home at Old Trafford. In his next innings, against Essex, he made 44.
The quick answer is yes: Adil Rashid's 5 for 85 for England against West Indies in Grenada in February 2019 was the most expensive five-for in an ODI, beating Scotsman Gordon Goudie's 5 for 73 against Australia in Edinburgh in 2009. It could have been worse: Rashid actually had 1 for 85 before finishing his spell with four wickets in five balls.
Navjot Singh Sidhu actually passed 50 in his first four ODI innings, although that run did include a match in which he didn't bat, as was stated in the column. And Kepler Wessels made half-centuries in his first four ODIs for South Africa, in 1991-92, having already played several for Australia.
