At Edgbaston Jimmy Anderson embarked on his tenth Ashes series. Has anyone else played in so many? asked Mark Carlisle form England 
 Jimmy Anderson has played a part in all ten Ashes series since 2006-07, although he might want to forget 2019 in England, when he managed only four overs before suffering an injury that kept him out for the rest of the summer.
 There's a complication here in that the Ashes were not officially at stake in several series (including one-off Tests). For a start the Ashes were inaugurated in 1882, after Australia won a Test 
at The Oval, so were not actually contested until 1882-83. More recently one-off landmark Tests in 1976-77, 1980 and 1987-88 are not official Ashes matches, while the ECB declined to put the urn up for grabs for the three-match series in 1979-80.
And so there are two answers to your question, depending whether you're talking about all England-Australia Tests, or just official Ashes matches. The only other player to have taken part in ten Ashes series since the Second World War is another Englishman, 
Colin Cowdrey, between 1954-55 and 1974-75, and including six in Australia. Sticking with Ashes-only for now, the English allrounders 
Johnny Briggs (1884 to 1899) and 
Wilfred Rhodes (1899 to 1926), took part in 11 Ashes series, while the famed Surrey opener 
Jack Hobbs featured in ten. Briggs actually almost made it 12 - he was named in England's team for the abandoned 1890 Test at Old Trafford, which does not count in the records. The Ashes-only record is held by another Australian, 
Syd Gregory, who featured in no fewer than 15 different series between 1890 and 1912; in all, he played 52 Tests against England. His sometime team-mate, wicketkeeper 
Jack Blackham, took part in 11 Ashes series.
On balance, I think the overall figures for all England-Australia series are more authentic. In all, Blackham played in 17 series against England, to Gregory's 15; another early Australian, 
Alec Bannerman, took part in 13 (only eight of them official Ashes encounters). Two more Australians, 
Allan Border and 
George Giffen, also took part in 11 (three non-Ashes each). Apart from Cowdrey and Hobbs, there are nine further players who have appeared in ten series, including Cowdrey and Hobbs, as well as 
Geoff Boycott, 
Graham Gooch, 
Rod Marsh and 
Steve Waugh, who all featured in at least one non-Ashes series.
Surrey scored 501 to beat Kent recently. Is this the highest fourth-innings total to win a match in England, or indeed anywhere? asked Chris Harvey from England 
 Surrey's 501 for 5 to defeat Kent 
in Canterbury last week was the fourth-highest successful run-chase in English first-class cricket, and second in the County Championship only to Middlesex's 502 for 6 to beat Nottinghamshire 
at Trent Bridge in 1925. 
At Lord's in 1896, Cambridge University amassed 507 for 7 to beat MCC, while four years later the Players defeated the Gentlemen 
at Lord's by reaching 502 for 8 in the second innings.
 Worldwide, a side has only successfully scored 500 or more to win on five other occasions. The highest is West Zone's 541 for 7 to beat South Zone in the final of India's Duleep Trophy 
in Hyderabad in 2009-10. The highest fourth-innings total, regardless of result, remains England's 654 for 5 (chasing 696) to draw against South Africa 
in Durban in 1938-39. For the full list of the highest fourth-innings totals (not just in wins),

The ICC batting rankings going into the Ashes series had Australians in the top three places. When was the last time this happened? asked Jamie Constantine from Australia 
 The ICC Test batting rankings issued just before the first Ashes Test 
at Edgbaston last week had 
Marnus Labuschagne at No. 1, with a ranking of 903. 
Steve Smith (885) was second, just ahead of 
Travis Head, whose 163 in the World Test Championship final against India 
at The Oval boosted his ranking to 884, one more than the New Zealander 
Kane Williamson.
 I heard that England never lost when Geoff Boycott scored a Test century. Is that true, and is it a record? asked Michael Richmond from England  
Geoff Boycott scored 22 Test centuries, and 
it's true that England did not lose any of those matches. It actually equalled the record at the time, which was held by another famous England batter in 
Wally Hammond. More recently, 
Ian Bell also scored 22 Test centuries, and England did not lose any of those matches either. The record, however, is now held by 
Graeme Smith: he scored 27 Test centuries, and South Africa never lost when he reached three figures. Next on the list is 
Gordon Greenidge, whose 19 Test centuries all came in West Indian wins or draws, with none in defeat.
 Louis Kimber was out obstructing the field in a match I was watching last week. How often has this happened in England? asked David Stevenson from Bristol 
 The Leicestershire batter 
Louis Kimber was given out obstructing the field against Gloucestershire 
in Bristol last week, after catching a ball that bounced up against him - he dropped the ball away from the stumps, but was given out on appeal. It's a dismissal that would have been recorded as "handled the ball" until the Laws were revised in 2017.
 Kimber's was the seventh obstructing the field dismissal in a first-class match in England (the fifth in the County Championship). The previous instance was by Surrey's 
Mark Ramprakash, also against Gloucestershire, 
in Cheltenham in 2011. England's 
Len Hutton was out obstructing the field - the only such instance in a Test match - against South Africa 
at The Oval in 1951. Overall, there have now been 35 instances of this type of dismissal in first-class cricket around the world.
