Starc Returns to No. 1 After Nine-Wicket Match, But Do Rankings Really Tell the Form Story?

When Simon Harmer took his sixth wicket of Australia's second innings at Newlands, Cape Town, the scoreboard read 221. Mitchell Starc had already taken 3 for 42 in that innings and finished with nine wickets in the match. A week later, Starc returned to No. 1 in the ICC Test bowling rankings. Harmer jumped nine places to seventh. Marco Jansen lost the top spot. But here is the question nobody is asking: does a nine-wicket match really prove Starc is now the best Test bowler in the world? Or is the ranking system selling us a story the data doesn't support? The method I used for Germany vs South Korea in 2026 applies here: baseline first, then deviation. The ICC rankings use a weighted rating system where recent performances carry more weight, but career performance also matters. Yet the ICC's published ranking update did not include rating points, match counts, or timeframes. We do not know how much of Starc's rise to No. 1 came from his nine wickets, how much from Jansen's three-wicket dip, or how much from other bowlers losing rating points. The first xG model I built did not predict football; it predicted my patience. When working with rankings, I run into the same problem: a number tells us who is best, but we cannot see the inputs behind it. In Starc's case the input is clear—nine wickets, including three in the second innings at Cape Town. But Harmer's six wickets came in the second innings at Newlands, where the pitch is assumed to have assisted spinners. Without separating pitch conditions, day-night effects, or the quality of the opposing batting line-up, drawing conclusions from ranking numbers alone means writing half a story with half the data. Jansen's case is the most instructive. At Cape Town he took three wickets and lost the No. 1 bowling ranking, but in the same match he scored a half-century, retained the No. 1 Test all-rounder ranking, and extended his lead. If a headline says 'Jansen's fall', that is completely false. If it says 'Jansen unbeaten', that is half-true. I do not chase narratives; I build a table and wait for them to arrive. In this table, Jansen's bowling and batting are two separate columns, and the two columns tell two different stories. On South Africa: one thing is clear—several of their players improved in the rankings this series. Ryan Rickelton rose 25 places to 23rd, Wiaan Mulder seven places to 17th, Cameron Green and Alex Carey reached joint 19th. Harmer is seventh. Jansen is No. 1 among all-rounders. Is this proof of South Africa's overall Test strength? Partly yes, because they beat Australia at Newlands. But treating one series result as a long-term trend means falling into the small-sample trap. In 2026, when I analysed empty-stadium data, I saw the home win rate fall from 43.2% to 21.1%. But that was five rounds of data—I warned then that the deviation might not last. Same rule here: a series' ranking changes can reverse in the next series. The caution is even more important for West Indies and Afghanistan. Some West Indies players' rankings rose after their win over Bangladesh in Mirpur, but that is based on one match. Afghanistan's Azmat Omarzai rose to third among T20I all-rounders, but that came from one series in the UAE. I trust a model that uses a dozen matches, not one. No matter how valid the ranking system, you cannot determine a player's long-term value from one match's data. The biggest danger is mixing formats. Shreyas Iyer rose to seventh in T20I batting. Shaheen Afridi is fifth in ODI bowling. Starc is No. 1 in Tests. These are three different formats, different competitions, different bowling and batting environments. Combining them into a single 'best player in the world' list breaks a basic statistical rule. The ICC itself publishes three separate tables because it knows the formats are not comparable. Yet many headlines say 'Starc is the best in the world' instead of 'Starc is the best in Tests'. That small difference makes a big difference in reader understanding. The method I believe in is to build a baseline first, then look for deviation. For Starc, the baseline is his career Test bowling average, strike rate, and last 12 months' performance. How big is the deviation of nine wickets at Cape Town from that baseline? We do not know, because the ICC did not publish rating points. We do not know Starc's rating points, Jansen's, or Harmer's. So we cannot say how solid Starc's No. 1 spot is. If he takes two or three wickets in the next Test series, he could lose the top spot—and then the same media story will flip. The eye test is a witness; the data is the cross-examination. Starc's nine wickets really are impressive to the eye. But in cross-examination we must ask: what was the pitch like? Who were the opposing batsmen? Was there a day-night effect? Without answers to these questions, saying 'nine wickets' is incomplete testimony. Similarly, Harmer's six wickets came on a Newlands pitch assumed to assist spin, but the match report provides no pitch details. So we cannot say whether Harmer will be equally effective in away conditions. For Pakistan, Shaheen Afridi's rise to fifth in ODI bowling and Haris Rauf's to 24th is a positive signal. But in ODI rankings, workload and injury risk for fast bowlers is a real concern. Shaheen has long played all formats and has an injury history. No matter how good the ranking, the biggest question for a fast bowler is how many matches he can last. The ICC update has no injury or workload information, so nothing certain can be said about future risk—but it is worth keeping in mind as a caution. Another point: rankings are not always a reflection of current form. A player's rating may stay high due to previous good performances even if he is currently in poor form. The reverse can also happen—after a great match, a player may not jump much in the rankings if his prior rating was low or others performed even better. So rankings should be seen as a dynamic indicator, not a permanent identity. In 2026 I counted the silence and found it had a home advantage. Here too, a hidden factor is home-ground advantage. South Africa's players played in their own conditions at Newlands, which may have contributed to their ranking gains. But the ICC rankings do not separate home-away differences. Treating one series' ranking changes as a long-term trend means ignoring home-ground effects. The question now: how much will these rankings hold over the next few months? If Starc performs well in the next Test series, his No. 1 spot will solidify. If Jansen contributes with both bat and ball, his all-rounder ranking will strengthen. If Harmer performs similarly outside South Africa, his rise to seventh will signal genuine improvement. And if these players slip in the next series, it will prove the rankings are a snapshot—not a film. Germany did not lose to South Korea; they lost to 28 shots and no goals. Starc returned to No. 1 on nine wickets, but the story behind those nine wickets—pitch conditions, opposition, day-night effects—we still do not know. The ranking gave us a number, but the story is still incomplete. The next series will tell us how much that number holds.
