Has any pair of batsmen shared two double-century stands in the same Test?
Also: how many Test grounds does Australia have?
The new Perth Stadium last week did become the tenth ground in Australia to stage a Test match. It has superseded the WACA, which had held 44 Tests since the first one in Perth in 1970-71. I'm sure you thought of the Melbourne Cricket Ground, which has had 110 Test matches so far, and the Sydney Cricket Ground, which has staged 106. Adelaide Oval comes next with 77, while the Gabba in Brisbane has staged 60. And so far there have been 13 Test matches at the Bellerive Oval in Hobart.
There hasn't yet been an instance of two batsmen sharing two stands of 200-plus in the same Test. The nearest approach came in Brisbane in 2015-16, when Australia's openers Joe Burns and David Warner put on 161 in the first innings against New Zealand, and 237 in the second. Their combined total of 398 is the highest by the same pair across two partnerships in a Test (there have been several higher partnerships in one innings).
A current batsman leads the way here: the Bangladesh opener Tamim Iqbal has so far amassed 2619 runs in 78 one-day internationals at the Shere Bangla Stadium in Mirpur. He recently overtook Sanath Jayasuriya, who made 2514 in 71 matches at the Premadasa Stadium in Colombo. Tamim's team-mate Shakib Al Hasan is third, with 2472 runs in Mirpur, while Mushfiqur Rahim lies fifth, with 2351 runs there. In between them comes Inzamam-ul-Haq, who made 2464 runs in ODIs in Sharjah.
Shai Hope's undefeated innings of 146 against Bangladesh in Mirpur and 108 in Sylhet give him a total of 254 runs without being dismissed. That's a long way down the overall list: Fakhar Zaman leads the way with 455 between dismissals, in Zimbabwe earlier this year. That broke the old record of 405, set by his fellow Pakistani Mohammad Yousuf in 2002.
It is true: the closing stages of the 1953 Ashes Test at The Oval were used for some time for BBC television test broadcasts during the day (there were no regular daytime programmes then). The clip showed England's Denis Compton pulling the boundary that won the match - and reclaimed the Ashes urn after 19 years in Australia's hands. You can see the final shot towards the end of this clip, although there's no sign of the bowler, Arthur Morris.
