Australia’s Test record at the Gabba makes it the most well-known fortress in cricket. Only one other home team have gone more than five Tests undefeated at a venue since 1990: India, nine matches without a loss at Delhi. Australia have played 25 Tests at Brisbane in this period.
There are various factors that explain this streak beyond ones specific to the venue. Australia have lost only 18 times in 143 home Tests in this period, with five reverses in 24 Tests at Perth their worst return.
Being the traditional series opener also helps Australia at the Gabba. In the last 10 years the difference between home team win and loss percentages in the first matches of series is 30% (48% won, 18% lost). It reduces to 22% in the second Tests of series and 18% in the third.
In this era of compressed tours and brief warm-up periods away teams often get caught cold in series curtain-raisers, regardless of the conditions.
However, the CricViz model is more concerned with the expected performance of the players involved in the game in question. It evaluates each player in the context of the opposition and the expected conditions.
It was Australia’s suitability to the bounce of the Gabba wicket that contributed to their win probability of 65% after the toss. They had the stronger seam attack and batting unit and the better spinner. New Zealand started at 27%, with 8% for the draw.
This is a seemingly low stalemate probability for a Test match, but a decent weather forecast and high projected scoring rates made this the least likely outcome, despite the good batting conditions.
The match unfolded in a way that was unsurprising to most observers. The Aussie openers survived a brief testing spell before piling up the runs against a toiling seam attack and a spinner who lacked control. The average projected outcome of a 223-run home win in PredictViz at the start of day two was very near the mark.
The suitability of the home seamers to Brisbane became clear when New Zealand batted. In the last 10 years 33.9% of Test wickets have been LBW or bowled. At the bouncier Gabba that figure is 24.1%.
|Wicket distribution||LBW||Bowled||LBW + Bowled|
|Gabba - home batsmen||7.9%||10.5%||18.4%|
|Gabba - away batsmen||13.5%||14.1%||27.6%|
Australian bowlers are largely responsible for this figure – 27.6% of the hosts’ wickets in this period have been LBW or bowled, compared with just 18.4% of visiting teams’ scalps. The extra pace of the home pacemen, of whom Mitchell Starc in particular likes to attack the stumps, was a major cause of New Zealand’s first innings collapse.
The Black Caps were seemingly cruising on a hot second day, 56 without loss in prime batting conditions. Most expected them to go on to score more than the 353 PredictViz projected, but the underlying expected averages produce a sound prediction when re-simulated 10,000 times.
New Zealand’s problems mounted throughout the Test. They have lost their all-rounder to injury – the performance of the fifth bowler is a key factor in the CricViz model – and have a concern over Tim Southee, a crucial part of their attack. Don’t be surprised to see a high Australia win probability at Perth, a venue that brings the opposition into the game more than most in Australia.
