Top batsmen in the W/BBL adjusted for point in the game

So yesterday I put together a blog post analysing how performance varies for batsmen based on which point in the match they come to the crease.

Today I’m going to show which players have performed the best in the Big Bash League and the Women’s Big Bash League, when their score is adjusted to reflect their opportunities.

This metric is based on this graph: how many runs does each batsman score, broken down by the over in which they entered the innings:

And here’s the same chart for women’s Twenty20 cricket:

The WBBL data includes the last four seasons of the state-based competition which preceded the WBBL, and it does appear that players in domestic Australian women’s Twenty20 cricket entering in the middle of the innings have performed better over the last five years.

This metric is simple. How does each batsman’s score compare to the median score for batsmen coming in to the innings in the same over for the period since July 2011? These measures (as a percentage) are then averaged to produce a figure for the entire 2016/17 season.

(Two notes: firstly, runs per innings is not the same thing as a batting average, as it doesn’t care whether the batsman was dismissed or survived without losing their wicket. Secondly, the data does not cover the matches played on Sunday 8 January 2017.)

This first table shows the top ten batsmen amongst those who usually bat in the top six for their team. Chris Lynn and Rob Quiney have both scored over 60 runs per innings. While Quiney has scored slightly more runs on average, Lynn normally enters around over 3, so his runs are slightly more impressive.

Sunil Narine and Mitch Marsh usually come in later in the innings, and Narine in particular is valued more highly thanks to late runs.

batsman team times batted total runs median entry point runs per innings scaled runs (%)
Chris Lynn Heat 5 309 3 61.80 346.82
Rob Quiney Stars 2 126 0 63.00 331.58
Sunil Narine Renegades 4 45 9.5 11.25 326.75
Mitchell Marsh Scorchers 5 210 11 42.00 275.79
Daniel Hughes Sixers 3 155 0 51.67 271.93
Ben Dunk Strikers 5 232 0 46.40 240.50
Kevin Pietersen Stars 3 148 2 49.33 238.89
Brad Hodge Strikers 5 204 5 40.80 231.47
Tim Paine Hurricanes 5 218 0 43.60 229.47
Brendon McCullum Heat 5 198 0 39.60 208.42

Here are the top batsmen who bat lower down the order. Ashton Agar has only scored 45 runs in four appearances, but for someone who usually only appears at the end of the innings this ranks him very highly. Interestingly Strikers bowler Billy Stanlake has only scored four runs in his first BBL season, but this is enough to put him above average thanks to his late entry.

batsman team times batted total runs median entry point runs per innings scaled runs (%)
Ashton Agar Scorchers 4 45 17.5 11.25 388.81
Kane Richardson Strikers 1 45 13 45.00 375.00
Beau Webster Hurricanes 1 67 6 67.00 304.55
Chris Green Thunder 4 39 16 9.75 230.56
Pat Cummins Thunder 5 133 13 26.60 207.19
Clive Rose Hurricanes 2 18 18.5 9.00 171.43
Jack Wildermuth Heat 2 37 14 18.50 168.68
Cameron Boyce Hurricanes 3 26 17 8.67 135.78
Billy Stanlake Strikers 3 4 20 1.33 133.33
Johan Botha Sixers 4 62 11 15.50 127.18

Before I move onto the WBBL, here are the worst ten rankings amongst batsmen who bat in the top six:

I have excluded anyone who has only batted once in the season, so Dom Michael and Jono Dean top the list thanks to each of them scoring two ducks in their two innings.

Particularly notable appearances on this list are two Sydney Thunder mainstays. Shane Watson had managed only six runs in his first three appearances as captain of the Thunder, and he did this despite usually coming in during the third over. Andre Russell was also performing poorly before his injury earlier this week, scoring only 25 runs in four appearances. (Shane Watson went on to score over 50 in last night’s match, but this data wasn’t available at the time of writing).

Shaun Marsh has scored 51 runs in four appearances, but this is particularly penalised because he has played as an opener for the Scorchers. This is a disappointment for them after he scored 29% of their runs in BBL05. Finally, Kumar Sangakkara has also performed poorly for someone who usually enters the match in the second over, managing only 68 runs in five appearances, before he was dropped by the Hurricanes for last night’s match against the Thunder.

batsman team times batted total runs median entry point runs per innings scaled runs (%)
Dom Michael Hurricanes 2 0 9.5 0.00 0.00
Jono Dean Strikers 2 0 9 0.00 0.00
Jake Lehmann Strikers 3 2 12 0.67 3.03
Shane Watson Thunder 3 6 3 2.00 11.01
Trent Lawford Renegades 2 6 13 3.00 34.45
Andre Russell Thunder 4 25 10.5 6.25 43.37
Shaun Marsh Scorchers 4 51 0 12.75 67.11
David Willey Scorchers 3 11 13 3.67 68.95
Ben Cutting Heat 3 27 12 9.00 72.49
Kumar Sangakkara Hurricanes 5 68 2 13.60 77.74

Now here are the similar stats for the women, starting with those who bat in the top six.

While Meg Lanning has been the top run-scorer, she ranks behind Sophie Devine and Amy Satterthwaite, who have each played fewer innings while also entering their innings at a later point.

Most batsmen playing in the WBBL score above the average for their role – which would match with other evidence that WBBL players score more runs overall than in other women’s Twenty20 included in the database.

batsman team times batted total runs median entry point runs per innings scaled runs (%)
Sophie Devine Strikers 5 230.00 4.00 46.00 375.63
Amy Satterthwaite Hurricanes 6 160.00 9.50 26.67 310.47
Meg Lanning Stars 9 384.00 0.00 42.67 304.76
Harmanpreet Kaur Thunder 8 194.00 9.50 24.25 303.15
Lauren Ebsary Scorchers 6 96.00 11.50 16.00 280.85
Katie Mack Stars 9 167.00 14.00 18.56 253.21
Ashleigh Gardner Sixers 8 225.00 5.00 28.12 250.11
Katherine Brunt Scorchers 6 105.00 13.00 17.50 242.46
Ellyse Perry Sixers 8 259.00 0.00 32.38 231.25
Alex Blackwell Thunder 9 253.00 5.00 28.11 217.73

And finally, the top ten batsmen who play in the lower order:

batsman team times batted total runs median entry point runs per innings scaled runs (%)
Sammy-Jo Johnson Heat 3 25.00 19.00 8.33 333.33
Veronica Pyke Hurricanes 4 60.00 17.00 15.00 281.25
Emma King Scorchers 2 8.00 19.50 4.00 250.00
Morna Nielsen Stars 2 6.00 19.50 3.00 175.00
Megan Schutt Strikers 4 33.00 16.50 8.25 161.67
Emma Kearney Stars 5 39.00 18.00 7.80 156.67
Megan Banting Scorchers 2 12.00 16.00 6.00 155.56
Kara Sutherland Heat 2 9.00 19.00 4.50 150.00
Jemma Barsby Heat 5 55.00 16.00 11.00 143.94
Annabel Sutherland Renegades 2 13.00 17.50 6.50 140.00

So what do you think? Is this a useful metric, and does it tell us anything more than a simple batting average?

As a final demonstration, these graphs identify players scoring over 300% in both the BBL and WBBL, on a chart comparing the runs scored per innings to the point where the batsman entered the innings.
