Both wicketkeepers failed to score in either innings in the recent Test at Lord's. Has this ever happened before? asked Sandy Whitlock from England
The fate of both wicketkeepers - Jonny Bairstow for England and Gary Wilson for Ireland - in bagging pairs in the action-packed match at Lord's last week was a first in Test cricket.

The previous low for wicketkeepers in a Test in which they both batted twice was two runs, in a match in Kanpur in 1959-60: Naren Tamhane scored 1 and 0 for India, and Barry Jarman 1 and 0 for Australia. The keepers contributed three runs in Port-of-Spain in 2001-02: Junior Murray made 0 and 1 for West Indies, and Ajay Ratra 0 and 2 for India.

England won their Test against Ireland despite making only 85 runs in their first innings. Have there been any lower first-innings totals that brought victory? asked Chris Mitchell from England
Ignoring the match in Centurion in 1999-2000, when England declared their first innings before it started and went on to win after South Africa forfeited their second innings, there have been just six lower first-innings totals than England's 85 against Ireland at Lord's last week that led to victory in a Test, only four of them in the opening innings of the match. Lowest of all is England's 45 in Sydney in 1886-87, when they bowled Australia out for 97 in the final innings to win by 13 runs.

Twenty wickets fell on the first day at Lord's - was this a record for the Home of Cricket? asked Savo Ceprnich from South Africa
Twenty wickets is indeed the most for the first day of a Lord's Test: 18 fell on the first day there in 1896, when England bowled Australia out for 53 and then amassed 286 for 8. Lord's also holds the overall record for wickets in a day's play: no fewer than 27 toppled on a rain-affected pitch on the second day of the match between England and Australia in 1888. England went from 18 for 3 to 53 all out, Australia made 60, then England were skittled for 62 to lose by 61 runs.

Was Ireland's 38 at Lord's the lowest score in the fourth innings of any Test? asked Jamie Stewart from Canada
Ireland's 38 at Lord's last week has been beaten - if that's the right word - twice before in the fourth innings, both times by South Africa early on in their time as a Test nation, against England. Needing 319 in Port Elizabeth in 1895-96, they were shot out for 30 (George Lohmann took 8 for 7). Then, in Cape Town in 1898-99, needing 246, they were demolished for 35.

To answer one final question about Ireland's 38, it was the lowest completed innings known to have included a six (by Mark Adair). The previous-lowest appears to be India's 42 against England in 1974 at Lord's - the previous-lowest Test total there - which included a six by Eknath Solkar. There are many innings for which we don't have full ball-by-ball details, although not many of them ended in a total of less than 38.

Who has scored the most runs in a Test series without making a century? asked Leo McGuinn from Ireland
This record is held by England's Mike Atherton, who made 553 runs in the 1993 Ashes series without making a century - he was memorably run out for 99 at Lord's after he slipped over on the pitch. That was one of six scores of 50 or more he made in that six-match rubber. The record for a five-match series is 550, by another stylish opener - West Indies' Conrad Hunte, against Australia in 1964-65. He also made six half-centuries, with a highest score of 89.

And here's an update to last week's answer about Super Overs that ended in a tie:
A number of readers have pointed out that there have been other matches that were decided on boundary countback, apart from the 2019 World Cup final at Lord's, and the IPL game in Abu Dhabi in 2014 so expertly described by Steve Smith last week.

The first time two teams were separated in this way was in Bridgetown in July 2010, when Barbados beat Combined Campuses and Colleges after ties in the match and Super Over. It happened again in a Champions League T20 match in Jaipur in September 2013, when New Zealand's Otago Volts beat the Lions from South Africa.

There have also been two similar results in the Women's Big Bash in Australia: in Sydney in January 2017, Sydney Thunder beat local rivals Sydney Sixers, while in another derby match, in Melbourne in January 2018, Melbourne Stars beat Melbourne Renegades.

The Super Over replaced a bowl-out in the event of a tie in a World Cup knockout match in 2011, and since then the boundary count has always been the first tie-breaker, in line with most domestic T20 competitions.

I'm sorry for missing these last week - I had asked a colleague if there were any others, as I couldn't think of any, and took their silence to mean I was right. Just shows you should never rely on your recollections in cricket!
