Pietersen's glorious debut and Waqar's batting distinction

Shane Warne dismissed Andrew Strauss six times in the Ashes series - is this a record? asked Amin Shukla from Trivandrum

The amazing Warne also dismissed Ashley Giles six times in the epic series that has just finished. As it turns out these were the 45th and 46th instances of a bowler taking the same batsman's wicket six times in the same series, starting in 1894-95, when England's Tom Richardson kept removing Syd Gregory. But the record is seven, which has happened four times now: the first was the South African Jack Siedle, who fell to a previous Australian legspinning legend, Clarrie Grimmett, seven times in 1935-36. Another South African opener, Trevor Goddard, lost his wicket seven times to Brian Statham in England in 1960. The other two are more recent: in the 1989 Ashes series Geoff Lawson dismissed David Gower seven times, while in 1997 Glenn McGrath accounted for Mike Atherton on seven occasions. While we're on this subject it might be worth mentioning the England opener Peter Richardson, who had eight innings in the 1956 Ashes series and was caught behind in each of them, although the bowlers were different.

Before the end of Kevin Pietersen's epic 158 at The Oval, a caption showed that he was approaching the record for the most runs in his debut Test series. Did he get there? asked Ben Elmington from Glasgow

He didn't quite break the record for England, which is still held by RE "Tip" Foster, who scored 486 runs in the 1903-04 Ashes series, including 287 on his debut at Sydney. But Pietersen did finish up with 473 runs in his first series, which puts him level in second place for England with Paul Gibb, who made 473 in South Africa in 1938-39, in the series that included the famous Timeless Test at Durban. George Gunn (462 in 1907-08) and Brian Luckhurst (455 in 1970-71) also made more than 450 runs in their first Test series for England. The Ashes record is 557, by Australia's Herbie Collins in 1920-21, while Arthur Morris (503 in 1946-47) also made more than any Englishman. But all of these are quite a long way adrift of the record for any debut series. In 1970-71 Sunil Gavaskar collected 774 runs in just four Tests in his maiden series, for India in the West Indies. He broke the previous record, George Headley's 703 for West Indies against England in 1929-30.

Who has scored the most Test runs without ever making a half-century? asked Nusrat Vohra from Pakistan

It's quite well-known that Shane Warne, with 2767 now, has scored the most Test runs without a century, but I'm not sure that I've ever been asked this question before, The answer is Pakistan's Waqar Younis, who's actually the only man to make more than 1000 Test runs without the aid of a fifty - his highest score in 87 matches was 45. Fred Trueman of England lies second with 981, ahead of Craig McDermott (940), Derek Underwood (937), Courtney Walsh (936), Andy Caddick (861) and Bob Willis (840). Caddick did have a near-miss - his highest Test score was 49 not out against Australia at Edgbaston in 2001.

Is it true that Jai Prakash Yadav's 69 in the recent Videocon Series was the highest score by a No. 9 in ODIs? asked Ganesh Mali from India

Yes, JP Yadav's 69 against New Zealand at Bulawayo last month did indeed break the record for the highest score by a No. 9 batsman in ODIs. The previous record was 64, shared by Michael Holding for West Indies against Australia at Perth in 1983-84, and Andy Bichel for Australia v New Zealand at Port Elizabeth in the 2002-03 World Cup. Tahir Naqqash hit 61 for Pakistan v New Zealand at Auckland in 1984-85, and there have been 14 other ODI half-centuries from Nos 9 or 10 in the order, three of them by South Africa's Lance Klusener, and one by Irfan Pathan in the same match as Yadav.

Recently Muttiah Muralitharan, almost unnoticed, went past Wasim Akram's overall record of international wickets, and is closing in on 1000. Who else has more than 800? asked Haider Abbas from Pakistan

Murali's nine wickets in last week's first Test against Bangladesh in Colombo took him to 939 international wickets all told - 558 in Tests and 381 in Odis. (He also has 999 Test runs as I write!) Wasim Akram did indeed hold the previous record, with 916, but Shane Warne has equalled him now. The only other one over 800 at the moment is Glenn McGrath, with 842, although Anil Kumble had 790 before the first Test against Zimbabwe.

Where does the name "Cross Arrows" come from? asked Stephen Sellick

The Cross Arrows Cricket Club is the one that plays matches throughout September on the Nursery Ground at Lord's. It's mostly made up of people who work there - MCC staff members as well as current and former groundstaff players. They play a high standard of club cricket, against local teams and organisations, as well as the occasional centenary or other celebration game. The Cross Arrows were founded in 1880, and legend has it that early on, before the club had a proper name, they had an away fixture out in the wilds of Middlesex. Asked where the match was, one of the players said "It's across 'Arrow way" (Harrow, home of the famous school, is out to the north-west of London) ... and the name stuck. I'm not quite sure if it's true, but it's a good story!
