Surfaces, Balls and Back-ups – The Areas Where the Ashes Will Be Decided
Just 48 hours to go.
The English side's first Test in Australia gets under way on Friday morning.
Drawing on analysis from cricket statistics experts, we look at where the highly awaited Ashes series in years could be determined.
It's tough to make runs, right?
Batters on each side of the Ashes divide might be wondering why they are even planning to turn up.
Much of the build-up has centred around the apparent difficulty of batting successfully, particularly for the opening match on a Perth pitch described as a "lush, challenging surface".
Regarding playing in Australian conditions, especially against pace bowling, no nation has been harder in which to accumulate runs over the past five years.
Two key factors for this: wickets and balls.
Taken as a collective, the pitches produced in Australia have been shown to be the fastest, most bouncy and among the least predictable in the world.
Speed and variable bounce are the perfect recipe for difficult batting conditions.
A long-standing narrative from England's cricketing circles describes the Kookaburra ball used in this country as a useless tool for a fast bowler.
A new version of the Kookaburra was introduced six years ago, resulting in increased seam movement.
Seam is a much bigger weapon than swing in Australian conditions.
Since the new Kookaburra, fast bowlers are conceding 25 runs per wicket in Australia.
Test match cricket is about solving problems.
When bowlers dominate, batsmen's contributions can be the deciding factor, and the reverse is true.
Should this series be bowler-dominated, a batter could have the chance to be the difference between the two teams.
What's going on with the Australia seamers?
On this occasion, England have toured Australia with their pace attack mostly fit, while the home side are the ones hit by injuries.
Skipper Pat Cummins will be absent for the first Test with a back issue, and Josh Hazlewood is unavailable for an unspecified time because of a hamstring injury.
Pat Cummins, Hazlewood and Mitchell Starc were first united as a three-pronged attack for the 2017-18 Ashes.
From that point, they have taken together 81% of the wickets taken by Australia pace bowlers in home Tests.
Australia have seldom needed alternatives because of the effectiveness and robustness of the 'leading trio'.
On the occasions Australia have needed a back-up, Boland has been sensational, taking 62 dismissals in 14 Tests at an average under 17.
Aside from Scott Boland, other bowlers of the backup squad have stepped up.
Neser, Jhye Richardson and Pattinson all average under 30 in domestic Tests.
The last time Australia entered a home match without both key bowlers, and were defeated, was in 2012.
On the last two occasions they have competed in Australia without the pair, they have won by a total of 694 runs, including a win against England in the Adelaide Test four years ago.
In infrequent cases Australia have had to go past their superstar pacemen, outcomes have remained strong – The tourists should pay attention.
Tough at the top
Recall the time England struggled to identify an opening batsman to go alongside Alastair Cook?
Sir Chef changed partners more quickly than Watford change coaches.
Not anymore.
Ever since Ben Duckett and Zak Crawley were united at the England opening slot at the close of 2022, no opening pair in the world has scored more runs together.
Their success as a combination has been a reason in Crawley being supported through some patchy form.
The Kent man, who memorably hit the first ball of the previous Ashes for a boundary, has also been identified as having the game for Australia.
His batting average rises when the pace increases.
In comparison, the Australian opening lineup is in a ongoing change, yet to fill the David Warner-shaped hole.
Following Warner's departure at the start of 2024, Khawaja has batted with five different partners in 15 Tests.
Yet to debut Jake Weatherald appears likely to become the sixth in 16 Tests on Friday, giving Australia an left-handed opening pair.
It's not only the openers that has posed issues for Australia.
Labuschagne, Australia's regular number three, was moved to open for the WTC final, then dropped entirely.
Home performances has brought him back, most likely returning to number three.
In seven Tests in the current year, Australia's top three average a collective of 25.37.
Only the top threes of Zimbabwe and West Indies have performed worse.
Spin war
For two so evenly-matched teams, there is one area where Australia are clearly stronger – spin bowling.
Australia's Nathan Lyon, with 562 Test wickets of him, is among the best finger-spinners to ever play.
Shoaib Bashir of England is a somewhat successful gamble, appearing out of touch after a finger injury, while Will Jacks is primarily a batter.
It would seem logical for the hosts to want Lyon at the front, but spin bowling has been incredibly hard work in Australia for the last decade.
In that time, spinners have averaged almost 44 in this country, albeit Lyon's statistics largely stands up compared to the struggles of overseas spinners.
Lyon's other issue is physically getting on to bowl.
Remember the effectiveness of pace bowling?
It limits the time Lyon has with the ball.
During the 2017-18 series here, Lyon was averaging 50 overs per Test.
In the previous year, in five Tests against the Indian team, it was only half as many.
Tests in Australia are lasting about 25% less time since the updated ball was brought in, meaning Lyon has fewer opportunities to make an impact.
Right place, right time?
The English team have a unfortunate tendency of being beaten in an away Ashes before Santa Claus has loaded his sleigh.
The series traditionally started in Brisbane, where they have not won since 1986.
In recent times, that has been followed by a floodlit Test in Adelaide Oval.
The visitors have one win in seven day-night matches worldwide, while the hosts have triumphed in 13 out of 14.
Then comes Perth, a city England have visited 14 times since 1970 and emerged victorious only once, against a depleted Australia in 1978.
On this tour, the initial three venues on the tour are the same, only in a rearranged order and under altered conditions.
Perth stages an Ashes opener for the first time, not at the fabled Waca – scene of many an England humbling – but the shiny new Perth Stadium.
It is still a tough assignment, though one the tourists tackle with no past burdens.
The Gabba is the location for the second Test, the day-nighter.
The last time Australia played a pink-ball Test at the Brisbane, they were surprised by the West Indies.
Likewise, the Australians are now unaccustomed to playing day matches at the usual day-night venue Adelaide Oval.
Across two traditional Tests played in the Adelaide since 2014, Australia lost one, to the Indian team, in 2018.
The re-jigged schedule gives England a new opportunity at starting an away Ashes well, albeit with pitfalls.
Australia have won four of the five Tests played at Perth Stadium, though the single loss came in the most recent match – against India the previous year.
Each match at the new ground has been claimed by the team batting first.
The English often overthink day-night matches, when data indicate the pink cricket ball does not perform much differently from its traditional red ball.
