72.07 Usman Khawaja's batting average while scoring 937 runs in Tests in Australia. His 138 not out in this innings is his fourth hundred in ten Tests at home. Khawaja is the first Australia batsman to make a hundred in his first innings as an opener in Tests since David Boon made 123 at the same venue against India in 1985-86.
12.37 Khawaja's batting average as an opener in first-class matches in Australia before this innings. He had made just 99 runs from eight innings with a highest of 28.
1992 Last time an Australia debutant at No. 5 failed to score at least a half-century. Damien Martyn had made 36 and 15 on debut against West Indies at the Gabba in 1992-93. Peter Handscomb is the sixth such Australia batsman since then to make at least a fifty on debut.
13.00 Kyle Abbott's bowling average in this series. Among overseas fast bowlers who have taken at least ten wickets in any Test series in Australia, Abbott's average is the third-best and the best since Richard Hadlee took 33 wickets at 12.15 apiece in the Trans-Tasman Trophy in 1985-86.
1.52 Abbott's economy rate in this innings - currently the second-best among quick bowlers to have bowled at least 25 overs in a Test innings at the Adelaide Oval in the last 50 years. Abbott has sent down 25 overs so far in this innings and has conceded just 38 runs. Khawaja's 16 runs off 46 balls are the most any Australia batsman has scored off him in this innings.
