Was India's 295-run win in Perth their biggest away in Tests?
And among openers who have played at least 50 Tests, who has the highest average?

India beat West Indies by 318 runs in Antigua in 2019, their biggest win away by runs • Getty Images
The 21-year-old Warwickshire left-hander Jacob Bethell made his Test debut at No. 3 against New Zealand in Christchurch last week - and hit the winning run as England won by eight wickets.
India's win in the first Test against Australia in Perth last month was their third-biggest by runs away from home: they beat West Indies by 318 runs in Antigua in August 2019, and walloped Sri Lanka by 304 in Galle in July 2017. Their previous biggest win in Australia was by 222 runs in Melbourne in 1977-78.
The Barbadian opener Kraigg Brathwaite has been ever-present in the West Indies team since June 2014, and the second Test against Bangladesh in Kingston was his 86th in a row (he had played a few before this run started, so now has 96 in all). The record he broke was the most consecutive Tests for West Indies without missing one, previously held by an even more distinguished Barbadian, Garry Sobers, who did not miss any of their 85 Tests between April 1955 and April 1972. Desmond Haynes played 72 successive Tests for West Indies, and Brian Lara 64.
You're right that it's a difficult place to bat: only 28 men who opened in at least 50 Tests have an average of 40 or more when doing so. Top of the list is the England opener of the inter-war years, Herbert Sutcliffe, who averaged 61.10 from 54 matches. He's ahead of two other England greats, Len Hutton (56.47) and Jack Hobbs (56.37). Of those who played in the current century the leader is Australia's Matthew Hayden (50.73). Sunil Gavaskar and Virender Sehwag of India both also averaged over 50.
Ivory Coast made a reasonable start to their reply to Nigeria's 271 in their recent match in Abuja - they had four runs on the board before the first wicket went down, but the rest managed only three between them. There were six ducks (and a 0 not out) in the final total of 7, which is a new low for men's T20Is: there had previously been two cases of 10 all out, by Mongolia against Singapore two months previously, and the Isle of Man vs Spain in February 2023. The lowest by a Test-playing nation is West Indies' 45 against England in St Kitts in March 2019.
