A study of converting Test fifties into hundreds-1

The ability to convert fifties into hundreds is useful in Tests, even more than converting centuries into double centuries. The “conversion rate” has not received much attention in statistical studies in the past.

If your career includes a score between 50 and 99 but no century, your conversion rate is 0%

If you have no score between 50 and 99 but one or more centuries, your conversion rate is 100%

Most Test batsmen will fall between these extremes (unless they never crossed 50).

Take Virat Kohli. He has 27 Test innings between 50 and 99. Oddly enough he also has 27 centuries.

So he has crossed 50 a total of 27+27 = 54 times, and has gone past 100 on 27 occasions. This is a conversion rate of (27/54)*100 = 50%.

One more example: Sachin Tendulkar has 68 innings between 50 and 99, besides 51 centuries.

So he crossed 50 a total of 68 + 51 = 119 times. His conversion rate is (51/119)*100 is 42.86%

Similarly, we can find Don Bradman’s conversion rate to be (29/(29+13)*100 = 69.05%

Let us now look at studies of all Test players up to Sep 30, 2021.

There are 56 players who have a 100% conversion rate, who have no score between 50-99 plus one or more centuries. The first few are:

RS Bopara is the only one with 3 centuries without any score between 50 and 99.

The next 5 have made 2 centuries, including Wasti who made both his centuries in the same Test.

And then there are 50 others who crossed 50 only once but went on to make a century, ranging from A Lyth to Yasir Shah. KK Nair has a triple century, while D Lloyd and B Kuruppu have doubles. There are a surprisingly high number of players who scored a century on debut and failed to cross 50 afterwards.

For a short time, Fawad Alam had made 4 centuries without a fifty. The record is by GA Headley of long ago, who made 6 centuries before making a fifty.

After crossing the 56 who have a 100% conversion rate with the help of one century, we get:

(This has a cutoff of 55%)

Fawad Alam leads with 5/6 or 83.33%, followed by JF Reid (of the 1980s) and Azhar Mahmood with 75%.

Current players here are Fawad Alam, Najmul Hussain Shanto, Abid Ali and SC Williams (Zimbabwe).

From India there is only S Dhawan and VG Kambli.

If you take those who have scored 10 or more centuries, only Bradman (69.05%) and Headley (66.67) have crossed 55%. The next few are Walcott (51.72), Azharuddin (51.16) and MJ Clarke (50.91)

Here is a complete list of those who scored 10 or more centuries at a conversion rate of 45% or more:

The only current players in this elite group are Kohli and SPD Smith (and M Hafeez from the recent past).

India is represented by Azharuddin, Kohli, Shastri (!) and Umrigar.

(Note that Hayden’s century and other scores in the ICC XI v Aus Test in 2005 have not been counted).

Let us look more closely at current players with 10+ centuries and conversion rates 35+

V Kohli 50.00

SPD Smith 46.55

DA Warner 44.44

Mominul Haque 44.00

D Elgar 43.33

KS Williamson 42.11

CA Pujara 36.73

LD Chandimal 35.48

TWM Latham 35.48

Azhar Ali 35.29

R Taylor 35.19

Note the absence of JE Root (31.51), BA Stokes (29.41), AM Rahane (33.33) and F du Plessis (32.26)

Certainly this last list has some surprises which contradict common perceptions about the heavy scorers of today.

In Part 2, we will look at the other end of the scale-those with the lowest conversion rates.

Century on debut and never again (May 2021)

Scoring a century on Test debut is not as difficult as one may think. As many as 108 players have scored 110 centuries on their Test debut, including LG Rowe and Yasir Hameed who scored centuries in both innings.

There are several who failed to score a century after their debut. The full list (up to 15/05/2021) is given below.

Players can drop off this list (as Fawad Alam did after over 11 years). Some current players (from PP Shaw downwards) can be reasonably expected to score another century sooner or later.

The most Tests played here are 25 by Yasir Hameed and 24 by L Amarnath. The latter was an useful bowler and a relatively better captain (by Indian standards of those days).

The most 50s scored after debut are 8 by Yasir Hameed and 7 by SK Raina. The latter was more successful in limited-overs matches, and was one of the first to score a century in a T20I.

Now we look at those who never crossed 50 after their debut.

Ganteaume played in only one innings. RE Redmond is not here as he scored a century and a fifty in his only Test.

The most Tests played among these players are 12 by van Zyl and 10 by DR Smith.

Fawad Alam (again!) got off this list after over 11 years.

There do not seem to be any current players here.

Records of Zimbabwe-Pakistan Test series-May 2021

Another one-sided series which was a common feature of the last few months.

Here is a full record of Tests between these teams:

Zimbabwe has only won 3 of these Tests. But they have been significant, as the first win in 1994-95 was Zimbabwe’s first win (though they lost the series 2-1). The second in 1998-99 ensured Zimbabwe’s first series win abroad. And the third in 2013 was one of their rare drawn series against a major team.

Highlights of this series: Babar Azam won all 4 of his first 4 Tests as captain.

Abid Ali’s 215* is the highest for Pak v Zim in Zim, surpassing Younis Khan’s 200* in 2013. The Pak v Zim record is still Wasim Akram’s 257* in 1996 at Sheikhupura.

He also became the first to make a score of 215* in a Test. Several others have been dismissed on 215, most recently MA Agarwal and M Labuschagne.

Nauman Ali (97 and 5-86) came close to becoming the first to make a century +5wi for Pakistan against Zimbabwe. PA Strang had already done this for Zim v Pak in 1996. That was the same match in which Wasim Akram scored 257*.

Fawad Alam now has the most centuries (4) without a score between 50 and 99. The previous “record” was 3 centuries by Ravi Bopara. However, it should be mentioned that ED Weekes made 5 centuries before making his first fifty (that too in 5 successive innings), and GA Headley went a step ahead with 6 centuries before stooping to a fifty.

Test centuries but no fifties (Aug 2019)

There seems to be a lot of interest in this older post about Karun Nair:

https://abn397.wordpress.com/2017/04/21/karun-nairs-test-records/

Particularly as he has now made a couple of good scores in domestic matches.

So we update an older post about those who scored Test centuries and no fifties.

One century and no fifties, arranged in order of highest score:

1 century and no fifty.JPG

Karun Nair tops this list, being the only one with a triple century and no fifty.

Then we have David Lloyd and Brendon Kuruppu. Lloyd’s double came in his second Test (against India’s ill-fated team of 1974), while Kuruppu scored his double on Test debut.

We then have a long list going down to TB de Bruyn, who is probably going to play again. Others who may play again would be Nair, KR Patterson, TA Blundell, GJ Maxwell and AG Cremer.

There are many who scored a century on debut, including Kuruppu, Fawad Alam, Khalid Ibadulla, Bannerman (in the very first Test), Griffith, Mills, Hartigan, Ali Naqvi, Abul Hasan, Ganteaume (only Test), Shodhan, Blundell, Hayes, Baichan, DR Smith, Milton, Wellham, Pataudi Sr and van Zyl. Of these club members, only Blundell is likely to leave.

If you were thinking of RE Redmond, he scored a century and a fifty in his only Test.

Now for those who scored two centuries and no fifties:

2 century and no fifty

Graham scored a century on debut. And W Wasti scored both his centuries in the same Test.

And only one has scored three centuries and no fifties:

3 century and no fifty

While Bopara continued to play limited-overs matches for England, he did not get a chance to score a fifty after his three centuries.

For a short time KL Rahul shared this record, as he scored three centuries before making his first fifty.

For a few months Fawad Alam surpassed this record as he got up to 4 centuries and no fifties. Today he has 5 centuries and one fifty. Earlier, GA Headley made 6 centuries before his first fifty.
