Batting by position number

Here's a question from Sanjit to get everyone in the mood for some Friday night indoor cricket.

Sanjit asked about the performance of batting pairs based on position in the innings. That is, how well does the opening partnership do compared to the pair who bat second, and third, and fourth.

As a side note: While doing this, I noticed something that I hadn't spotted before. The Popped Collars last game at Lyneham was actually their 150th match! Well done lads... onwards to 200!!

Also note: all the numbers in this post only use stats from 8-a-side games. There's not much use comparing 8-a-side and 6-a-side in this particular stat.

Let's start with the overall averages. The table below shows the basic stats for and against the Popped Collars, separated by pair number. Clearly, we score far more runs that our opposition (our lowest average is more than their highest!), but the pattern for both teams is the same:

POPPED COLLARS
Pair # Innings
RunsAverage
First150 6588 43.92
Second150 5429 36.19
Third150 5034 33.56
Fourth150 5473 36.49

OPPONENTS
Pair # Innings
RunsAverage
First150 5019 33.46
Second150 4263 28.42
Third150 3837 25.58
Fourth150 4175 27.83


In both case, the opening pair is clearly the highest, and the third pair clearly the lowest - second and fourth are in between, and are quite close to each other.

It seems that teams like to get off to a good start! Perhaps they put their good batting pairs in first? Let's investigate....

The first thing you might think regarding the Popped Collars opening partnerships is "Julian and Xavier". They batted together for a long time at the top of the order and have one of the highest averages of all the regular batting pairs. But while they do keep the first-pair average from dropping, they are not the stars of the #1 position.

In fact, if you look at all the partnerships that have opened the innings regularly (at least 10 times), Jules and X actually have pretty much the LOWEST average! Check it out...

OPENING PAIR
Batters Innings
RunsAverage
Julian Xavier60 2699 44.98
Brad Sanjit26 1181 45.42
Brad Xavier17 853 50.18
Daniel Xavier14 629 44.93
Gareth Rian12 557 46.42
All Others21 669 31.86


Batting at the top of the order seems to give batters some kind of advantage!

A cynical reader may be tempted to accuse Julian and Xavier of having high averages only because they bat at the start of the innings - not because they have any actual skill!

Here's similar tables for the second, third and fourth pairs. If you want some evidence of "batting first improves your average", have a look at Brad and Sanjit's averages, 10 to 15 runs lower than compared to when they open!

SECOND PAIR
Batters Innings
RunsAverage
Brad Sanjit44 1595 36.25
Gareth Rian27 1150 42.59
Andy Matt6 137 22.83
Julian Xavier6 319 53.17
All Others67 2228 33.25

THIRD PAIR

Gareth Rian32 1170 36.56
Andy Jake22 862 39.18
Brad Sanjit5 160 32.00

FOURTH PAIR

RunsAverage
Andy Jake37 1252 33.84
Julian Xavier9 365 40.56
Gareth Rian9 308 34.22
Brad Sanjit8 246 30.75
All Others87 3302 37.95


Another explanation for the overall batting position averages could be consistency. Popped Collars have used only 23 different opening combinations over their 150 games, while the others are all up around (or above) 50 different combinations of batter. The less combinations, the higher the average.

Pair # Average
Combinations
used
First43.9223
Second36.1952
Third33.5659
Fourth36.4949


Lessons learned this week - if you want to improve your batting stats, bat first, and bat with the same partner. Or just play in the Kaleen 6-a-side competition...
