That's a nice easy one, as those 25 different wickets by Kraigg Brathwaite is the Test record. Next comes Mohammad Ashraful, whose 21 wickets for Bangladesh were all different people. The Sri Lankan left-arm seamer Sajeewa de Silva follows him with 16, one more than the Surrey and England pair of Gareth Batty and Mark Butcher.
The match that the Association of Cricket Statisticians and Historians considers to be the inaugural first-class fixture was played 250 years ago this year: on Broadhalfpenny Down in Hambledon, Hampshire beat "England" by 53 runs in a two-day game that started on June 24, 1772. John Small, one of the game's first notable batters, made 78 for Hampshire; the might of England managed only one run more between them in their second innings. Three years later, also at Hambledon, Small made what is now recognised as the maiden first-class century - 138 for Hampshire against Surrey.
That double by Joe Root (153) and Kraigg Brathwaite (160) in the second Test in Bridgetown was the eighth time both captains had made a score of 150 or more in the same Test. The first such double was at Old Trafford in 1964, when Bob Simpson amassed 311 for Australia and Ted Dexter responded with 174 for England. The most recent instance before last week came in Abu Dhabi in March 2021, when Asghar Afghan made 164 for Afghanistan and Sean Williams 151 not out for Zimbabwe.
Unlike in Tests (15 instances so far), there hasn't yet been a one-day international innings in which everyone reached double figures. There are four cases of ten getting there. When West Indies made 246 against Australia in Bridgetown in 1990-91, everyone reached double figures except last man Courtney Walsh, who was out for 4. Pakistan's 259 for 9 against West Indies in Dhaka in 1998-99 included ten double-figure scores, plus 4 from Shahid Afridi, who opened. When Zimbabwe scored 262 against India in Rajkot in 2000-01, last man Brian Murphy was out for 1. And Robin Uthappa also made 1 as India totalled 275 against Pakistan in Jaipur in 2007-08.
Both of these things were records, depending on how you define them. At 17, Kumar Kushagra was the sixth youngest to score a first-class double-century - Hasan Raza, whose age is disputed, was reportedly only 15 when he scored 204 not out for Karachi Whites against Bahawalpur in Karachi in 1997-98. The others were Ijaz Ahmed (16 in 1984-85), and 17-year-olds Reetinder Sodhi (1997-98), Ambati Rayudu (2002-03) and Johann Myburgh (1997-98). But none of those younger than Kushagra made it to 250, so he is the youngest to reach that particular milestone.
