BBL – each squad’s batting/bowling stats

I had a bit of writer’s block thinking about how to preview the BBL season, which starts on Thursday. There’s so much potential data about the players, and it’s hard to decide what is likely to provide new insights, rather than just demonstrating what is already conventional wisdom.

I decided to follow roughly the same model as I used for the WBBL. So I’m going to post here today the key batting and bowling stats for each squad selected for the BBL. I’m also going to do some analysis of what the equivalent numbers looked like prior to last season to see how useful it is in predicting outcomes.

Tomorrow I will post about the key individual players to watch, according to these same statistics.

For my WBBL preview, I used seven key metrics: four for batting and three for bowling. After more analysis, I’m slightly changing two of them:

  • Wickets taken per innings becomes wickets taken per over – to account for the fact that some bowlers don’t bowl their full four overs.
  • Instead of counting the total number of boundary runs per innings, I’m counting the proportion of total runs scored on the boundary.

Firstly, I’m going to post these stats for players who played in BBL 4 (2014-15) as of 30 November 2014, and include all Twenty20 matches played by those players. For batting stats, I only include innings in the top 7.

Batting stats, BBL4 squads as of 30/11/14

Team # of innings Average Strike rate Balls/ innings Boundary runs %
Heat 406 21.97 126.65 14.49 0.55
Hurricanes 754 27.65 129.08 17.19 0.56
Renegades 789 25.79 131.06 15.91 0.56
Scorchers 529 30.21 124.96 20.24 0.53
Sixers 469 23.52 131.76 15.38 0.61
Stars 912 28.06 136.43 17.07 0.58
Strikers 768 31.26 137.33 17.13 0.58
Thunder 776 28.76 125.26 19.64 0.57

Bowling stats, BBL4 squads as of 30/11/14

Team # of innings Average Economy Wickets/over
Heat 531 25.96 7.41 0.2855
Hurricanes 524 25.35 7.38 0.2912
Renegades 615 24.67 7.62 0.3091
Scorchers 431 22.45 7.62 0.3396
Sixers 461 25.83 7.58 0.2936
Stars 609 26.93 7.83 0.2908
Strikers 796 24.03 7.56 0.3145
Thunder 568 25.02 7.58 0.3030

Some of these statistics correlated quite strongly with each team’s net run rate (as a proxy for their performance), in particular batting average and wickets taken per over, but when I went back and conducted the same analysis on the previous three BBL seasons the correlations were completely different. That analysis is a story for another day.

Next up are the equivalent figures for the coming season.

Batting stats, BBL05 squads as of 2/12/15

Team # of innings Average Strike rate Balls/ innings Boundary runs %
Heat 429 25.5 120.58 18.48 0.58
Hurricanes 672 24.73 127.82 15.98 0.54
Renegades 789 31.37 134.46 19.13 0.62
Scorchers 616 31.7 126.87 20.97 0.54
Sixers 659 23.65 125.88 15.57 0.57
Stars 898 27.34 138.34 16.51 0.58
Strikers 494 31.71 131.61 19.85 0.60
Thunder 846 30.1 128.77 18.96 0.57

Bowling stats, BBL05 squads as of 2/12/15

Team # of innings Average Economy Wickets/over
Heat 338 25.62 7.04 0.2747
Hurricanes 520 24.41 7.86 0.3219
Renegades 651 25.83 7.80 0.3019
Scorchers 382 21.80 7.32 0.3356
Sixers 599 25.18 7.34 0.2916

Strikers 279 24.49 7.87 0.3213
Thunder 649 27.12 7.79 0.2872

The reigning champion Scorchers still have batsmen who have faced the most balls per appearance. On batting average, the Scorchers, Strikers and Renegades all stand out, with the Thunder not far behind. The Renegades have made the biggest increase in their batting average since last season, with the Thunder and Scorchers also picking up ground. The Sixers remain the team with the lowest batting average in their players’ careers.

The two Melbourne teams have the fastest-hitting batsmen, with the Brisbane Heat at the lower end.

The Scorchers have bowlers who take the most wickets, followed by the Hurricanes.

I’ll return tomorrow with a post about individual players worth watching in this season.
