Both New Zealand's openers made ducks in the Dunedin ODI, but their team still won. How often has this happened? asked Graham Monk from New Zealand
Those blobs by Martin Guptill and Colin Munro against England in Dunedin the other day represented the 41st time in all one-day internationals that both openers on one side were dismissed for ducks. In ten of those matches - including this one - the team concerned recovered to win. Probably the most famous of those was the first of them: during the 1983 World Cup in Tunbridge Wells, India lost Sunil Gavaskar and Kris Srikkanth for ducks, and were soon 17 for 5 against Zimbabwe - but thanks to Kapil Dev's rampaging 175 not out, they managed to make 266, which proved enough for victory and India went on to win the tournament.

Which ground has witnessed the most triple-centuries in first-class cricket? asked William Taylor from England
The most batsman-friendly ground in this respect is The Oval, which has been the stage for 11 triple-centuries in first-class cricket, most recently Kevin Pietersen's unbeaten 355 for Surrey against Leicestershire there in 2015. The highest score at The Oval remains Neil Fairbrother's 366 for Lancashire v Surrey in 1990, which just eclipsed Len Hutton's 364 for England in the 1938 Ashes Test. The others to reach 300 at The Oval are Bobby Abel (357 not out in 1899), Walter Read (338 in 1888), Tom Hayward (315 not out in 1898), Walter Keeton (312 not out in 1939), Hashim Amla (311 not out in 2012), Andy Ducat (306 not out in 1919), Mark Ramprakash (301 not out in 2006), and Raman Subba Row (300 in 1958).

There have been nine scores of more than 300 in first-class cricket at Taunton (including quadruple-centuries by Archie MacLaren and Graeme Hick), eight at the Melbourne Cricket Ground (four of them by Bill Ponsford), six in Adelaide, and five each at Lord's, the National Stadium in Karachi, the Sydney Cricket Ground, and both the Brabourne and Wankhede Stadiums in Mumbai.

I noticed on the TV that Jos Buttler had an ODI strike rate of 118. Is this the highest of any current player? asked Damian Gresswell from New Zealand
After the recent series in New Zealand, Jos Buttler's one-day international strike rate stood at 118.02 runs per 100 balls. That's the most of anyone with more than 2000 ODI runs, apart from Australia's Glenn Maxwell, who is zooming along at 123.08. Andre Russell, the West Indian who hasn't appeared in an official ODI since 2015, has scored 985 runs at a strike rate of 130.81. If you increase the qualification to 3000 runs, then Shahid Afridi takes over: in all, he bludgeoned 8064 runs in ODIs at a dizzying rate of 117. The only others with more than 2000 ODI runs at a strike rate better than 100 - a run a ball - are Virender Sehwag (8273 at 104.33), Jason Roy (2006 at 102.60), David Miller (2503 at 101.13) and AB de Villiers (9577 at 101.09).

Who has taken the most caught-and-bowleds in Tests? And what's the highest Test score ended by one? asked Mohammad Alam from India
There's a tie at the top of this table: Anil Kumble and Muttiah Muralitharan both claimed 35 Test wickets caught and bowled. Some way behind come Daniel Vettori and Shane Warne, with 21 apiece, then Derek Underwood, with 20. Of bowlers with more than 100 wickets, the man with the highest percentage of c&bs is the old Australia offspinner Hugh Trumble, with 10.63% (15 of his 141 wickets).

As for the second part of your question, a total of 139 Test centuries have so far been ended by a return catch. Highest among them is Virender Sehwag's 293 for India against Sri Lanka in Mumbai in 2009-10, when he became the last of those 35 c&b victims for Murali.

Is Jhulan Goswami the first woman to take 200 wickets in ODIs? asked Jamie Stewart from Canada
The India seamer Jhulan Goswami claimed her 200th one-day international wicket - Laura Wolvaardt - in India's comfortable victory over South Africa in Kimberley last month. It was Goswami's 166th match of a career that began back in January 2002, when she was 19. She had overtaken the previous record - Cathryn Fitzpatrick's 180 for Australia - during another match against South Africa, in Potchefstroom in May 2017. Among current players, the West Indian Anisa Mohammed leads the chasing pack, with 145 ODI wickets. Her team-mate Stafanie Taylor has 130, while the England pair of Jenny Gunn and Katherine Brunt have 135 and 127 respectively. For the full list, click here.
