Sarfaraz Khan, Gidron Pope, Alzarri Joseph, Avesh Khan, Jack Burnham. Names that have earned recognition for performances at the Under 19 World Cup this month. But will they, and their peers at this tournament, be the successors to Brendon McCullum, Mitch Johnson, MS Dhoni and Kumar Sangakkara in the wider consciousness of world cricket?

An analysis of previous Under 19 World Cup participants will not tell us specifically whether, say, Keemo Paul will become better known for his exploits as a senior than junior international cricketer. It will, though, cast some light on the development of international cricketers.

For every member of a full nation squad at the Under 19 World Cups of 2000, 2002, 2004 and 2006, I have recorded the highest level of senior cricket attained in their career. The ten year elapse since the most recent tournament reviewed makes it unlikely that any of the 555 players will reach a new peak. Unlikely, but not impossible: Stephen Cook, graduate of the 2002 tournament, made his Test debut this year.

Four levels of senior cricket have been identified, in ascending order: i) professional limited overs (List A or national T20 tournament), ii) first class, iii) international limited overs (ODI or T20) and iv) Test. With very few exceptions, this grading represents progress in a player’s career – ie he will have played the form of cricket considered lower than the level I have taken to be the highest level he attained.

Within each level, there is a broad range of attainment, measured by appearances. For example, from the 2000 tournament, grouped together at the first class level are Mark Wallace (England) with 249 appearances and Gareth Irwin (New Zealand) who played a single first class match in 2002/03. (Irwin is one of the exceptions to my hierarchy, as he did not appear in professional limited overs fixtures.) It might be fairer, therefore, to think of each group as containing players who have passed a common threshold, rather than attaining the same level.

The summary analysis of the 555 players shows that 45% have gone on to play international cricket (not all with the nation they represented at the Under 19 age group). 5% have not played any professional senior cricket.

I would have hypothesised that the conversion rate of under 19 internationals to senior internationals would have increased over this period; this being a reflection of the more structured approach taken towards the development of youth cricketers. The results don’t support that hypothesis: the proportion of under 19 players going on to play international cricket has varied: 2000 – 48%; 2002 – 40%; 2004 – 46%; 2006 – 42%.

There are some stark country-by-country differences. The youngsters of Bangladesh and Zimbabwe have had a higher likelihood of becoming full internationals, two-thirds in the latter case – perhaps reflecting that selection in those countries is from a smaller pool of players. On the other hand, barely one-quarter of those who have appeared at under 19 World Cups for England have played for the senior team. Unsurprisingly, England, with its 18 first class counties has had no players fail to reach the senior professional game – nor did Pakistan, South Africa and India.

I also looked at whether performance at the under 19 World Cup was a good predictor of future prospects by narrowing the analysis to the top run scorer and wicket taker for each of the ten nations at the four tournaments. 50 of the 81 players in this sample (64%) have played senior international cricket, compared to 55% of the total population, which is less of an increase than I would have expected. The outlier is New Zealand’s Jonathan McNamee, who was their top scorer at the 2000 tournament, but has no senior professional record.

At the team level, success in the under 19 tournament has not been associated with having teams choc full of future international cricketers. Looking at the eight finalists in these four tournaments, 43% (Test: 31%; Limited over: 12%) of their squad members went on to play senior international cricket, compared with 45% (35%; 10%) of the total.

I was also interested in understanding the proportion of players who reach Test level who have been participants at the junior World Cup. My method provides an estimate, not a precise figure. I extracted the number of Test debutants for each nation in the period 2002-2012. The chart below shows the number of players in the four under 19 World Cups who went on to play Test cricket and the proportion they are of the total debutants in the eleven year period. It provides a rough, rather than definitive, picture as some participants in those four tournaments had debuts before and after the eleven year period; and some players from the 2008 and 2010 tournaments probably had debuts during the period.

Approximate though this analysis is, it does show that England and Zimbabwe are outliers. Around half the Test debutants from the other eight nations had played in the four under 19 World Cups. For England, that figure was below one-quarter. At the other extreme, those players accounted for over 90% of Zimbabwe’s Test debutants.

There are positive and negative connotations to these two extremes. England’s position could be evidence that it performs poorly at identifying future talent, or that its junior cricketers mature at a later age. It could be a strength that international selection remains open to players emerging from outside of the elite juniors. England may have the resources to invest in a broader base of juniors, making precise selection at 19 difficult. Experience of international cricket as a teenager may be a poor one, having a negative impact on English juniors, or their development is interrupted by injury. The opposite to each of these arguments can be made for Zimbabwe. The data cannot help us with this key point. I would be interested in the views of readers.

In conclusion, the data analysis shows:

Unless from England or India, an Under 19 World Cup participant has close to, or better than, an evens chance of senior international cricket.

The first class game should definitely be within reach – if not already attained.

Having a strong tournament (relative to your teammates), desirable in its own right, boosts by a modest amount a player’s likelihood of moving onto senior international cricket.

At Test level, there is a heavy dependence on Under 19 World Cup graduates, with around one-half of the debutants in the years following tournaments having participated in the junior World Cup.

England and Zimbabwe are, respectively, less and more likely to choose Test debutants from Under 19 World Cup players.
