Apparently the new Perth Stadium is the tenth Australian ground to have a Test. Is that right? I can only think of seven! asked Kevin Larkham from Australia
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 It has superseded the WACA, which had held 44 Tests since the first one in Perth in 1970-71.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.
Now things get a little more difficult: three other Australian grounds have staged two Tests each. The Exhibition Ground in Brisbane staged an Ashes Test in 1928-29 - Don Bradman's debut - and another in 1930-31, before being superseded by the Gabba. And in 2003 and 2004 there was a brief experiment with "Top End Tests", in the tropical north of Australia, which led to two matches being played at the Marrara Oval in Darwin, in the Northern Territory, and two at Cazaly's Stadium in Cairns, in north Queensland.
There should be another addition to the list next year, as the Manuka Oval in Canberra has been allocated a Test against Sri Lanka. It will be the first Test in Australia's capital city. The ground has staged nine one-day internationals, including a 2015 World Cup match in which Chris Gayle thrashed 215 against Zimbabwe.
Has any pair of batsmen ever shared two double-century partnerships in the same Test? asked Mark O'Riordan from Ireland
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).
In all, there have been 43 cases of two batsmen sharing a pair of century stands in the same Test, most recently 246 and 144 by Kraigg Brathwaite and Shai Hope for West Indies against England at Headingley in 2017. Of those, the only other one to include two partnerships of 150 or more occurred in Johannesburg in 1938-39, when Paul Gibb and Eddie Paynter put on 184 and 168 for England's second wicket against South Africa. Gibb, who was making his debut, scored 93 and 106.
I know that Mahela Jayawardene holds the record for the most Test runs on a single ground. But who holds the corresponding record for ODIs? asked Nishantha de Silva from Sri Lanka
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.
You're right to say that Mahela Jayawardene holds the record for Tests: in fact he's first and second on that particular list, with 2921 at the Sinhalese Sports Club in Colombo, and 2382 in Galle.
Shai Hope just scored two unbeaten centuries against Bangladesh. Is this a record for the most runs without being out in ODIs? asked Jimmy Collymore from Barbados
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.
But only two West Indians have done better than Hope: Desmond Haynes scored 346 ODI runs between dismissals in April 1985, while Brian Lara made 255 in June 2003. As he was not out in his most recent innings, Hope's sequence is still continuing, so if he scores two runs in his next innings - probably against England early next year in the Caribbean - then he will pass Lara and have only Haynes to chase.
Is it true that Arthur Morris' last over of the 1953 Ashes was used as a BBC test card? asked Will Elsom from England
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.
A fine opener who averaged over 46, Morris didn't get much chance to show off his left-arm wristspinners in Tests. He took only two wickets - but one of them did come earlier in that 1953 series, in the third match at Old Trafford. Amusingly, it was his old tormentor (and close friend) Alec Bedser, who got Morris out no fewer than 18 times in Tests, a record at the time, since surpassed only by Glenn McGrath, who dismissed Mike Atherton on 19 occasions.
