Surfaces, Balls and Reserves – Where the Ashes Will Be Decided

Just 48 hours remaining.

England's opening match in Australia begins on the morning of Friday.

Drawing on analysis from CricViz, we look at where the highly awaited Ashes series in years could be decided.

It's tough to score runs, isn't it?

Batters on each side of the Ashes rivalry might be wondering why they are even planning to show up.

A lot of the build-up has focused on the perceived challenge of scoring runs, particularly for the first Test on a Perth pitch described as a "lush, challenging surface".

When it comes to playing in Australian conditions, especially against pace bowling, no country has been more difficult in which to score runs over the past five years.

There are two reasons for this: wickets and balls.

Overall, the surfaces prepared in Australia have been shown to be the fastest, highest bouncing and among the least predictable in the world.

Pace and variable bounce are the ideal combination for tough batting.

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.

An updated model of the Kookaburra was introduced six years ago, resulting in more seam movement.

Seam bowling is a much bigger weapon than swing in Australian conditions.

After the new ball's introduction, pace bowlers are averaging 25 runs per wicket in Australia.

Test match cricket is about problem solving.

When the ball is on top, performances of batters can be the difference, and the reverse is true.

If this Ashes be dominated by the ball, a batsman could have the opportunity to be the difference between the two teams.

What’s happening with the Australian pace attack?

On this occasion, England have toured Australia with their pace attack largely intact, while the hosts are the ones affected by fitness issues.

Captain Pat Cummins will be absent for the first Test with a back injury, and Josh Hazlewood is on the sidelines for an unknown period because of a hamstring problem.

Pat Cummins, Josh Hazlewood and Starc were first paired as a trio for the 2017-18 Ashes.

From that point, they have combined to claim 81% of the dismissals taken by Australian fast bowlers in home Tests.

The Australian team have rarely had to look elsewhere because of the effectiveness and robustness of the 'big three'.

When Australia have required support, Boland has been outstanding, taking 62 dismissals in 14 matches at an average under 17.

In addition to Boland, other bowlers of the backup squad have performed well.

Neser, Richardson and Pattinson all average below 30 in domestic Tests.

The most recent occasion Australia went into a home Test without Cummins and Hazlewood, and lost, was in the year 2012.

The past two times they have played at home without the duo, they have won by a combined 694 runs, including a victory against England in the Adelaide Test previously.

On the rare occasions Australia have had to look beyond their superstar pacemen, results have not been affected – England should pay attention.

Tough at the top

Remember when England struggled to identify an opening batsman to go alongside Alastair Cook?

Sir Chef went through partners faster than Watford change coaches.

No more.

Since Duckett and Zak Crawley were united at the top of the England order at the end of 2022, no opening pair in the world has scored more runs together.

The pair's effectiveness as a partnership has been a reason in Zak Crawley being supported through some inconsistent times.

Crawley, who famously struck the first ball of the last Ashes series for four, has also been identified as having the technique for Australian conditions.

His batting average increases when the bowling gets faster.

In comparison, the Australian opening lineup is in a ongoing change, yet to fill the David Warner-shaped hole.

After Warner's departure at the beginning of 2024, Usman Khawaja has batted with five different partners in 15 matches.

Uncapped Weatherald appears likely to become the sixth opener in 16 on the opening day, giving Australia an all-left-handed opening combo.

It is not just the openers that has posed issues for Australia.

Marnus Labuschagne, Australia's regular number three, was moved to open for the World Test Championship final, then dropped entirely.

Home performances has earned him a recall, probably back at three.

Across seven matches in the current year, Australia's top three average a collective of 25.37.

Only the opening trios of Zimbabwe and West Indies have performed worse.

Spin war

Between two closely matched sides, there is one area where Australia are clearly stronger – spin bowling.

Nathan Lyon of Australia, all 562 Test wickets of him, is one of the finest finger-spin bowlers to ever play.

England's Shoaib Bashir is a moderately successful selection punt, appearing out of touch after a finger injury, while Jacks is primarily a batter.

It would seem logical for the hosts to want Lyon at the forefront, but spin bowling has been incredibly hard work in Australia for the last decade.

During that period, slow bowlers have averaged almost 44 in Australia, albeit Lyon's statistics largely stands up compared to the struggles of overseas spinners.

Another challenge for Lyon is physically getting on to bowl.

Remember the effectiveness of fast bowling?

It limits the time Lyon has with ball in hand.

During the 2017-18 series here, Lyon was bowling 50 overs per Test.

In the previous year, in five matches against India, it was half that number.

Tests in Australia are lasting about 25% less time since the new Kookaburra was introduced, meaning the spinner has fewer opportunities to make an impact.

Right place, right time?

The English team have a unfortunate tendency of being defeated in an away Ashes before Father Christmas has loaded his sleigh.

The series began in the Gabba, where they have not won since the year 1986.

In recent times, that has been followed with a day-night Test in Adelaide Oval.

England have one win in seven day-night matches worldwide, while Australia have won 13 out of 14.

Then comes Perth, a city England have played at on 14 occasions since 1970 and won only one time, against a weakened Australia in 1978.

This time, the first three stops on the itinerary are the identical, only in a different order and under different circumstances.

Perth stages an Ashes opener for the first time, not at the famous Waca – scene of many an England humbling – but the shiny new Perth Stadium.

It remains a difficult task, though one the visitors tackle with no past burdens.

The Gabba is the location for the second Test, the day-night fixture.

The last time Australia competed in a day-night Test at the Gabba, they were surprised by West Indies.

Likewise, the Australians are now unaccustomed to playing day matches at the typical floodlit ground Adelaide Oval.

In the two red-ball matches played in the Adelaide since 2014, Australia were defeated once, to the Indian team, in 2018.

The revised fixture list gives England a new opportunity at starting an away Ashes well, though with risks.

The home side have secured victory in four out of five matches played at Perth Stadium, though the one defeat came in the most recent match – against India the previous year.

Every Test at the new ground has been won by the team setting a target.

England often overthink day-night matches, when data indicate the pink cricket ball does not perform much differently from its red counterpart.
