Fielding Statistics: A New Approach

[viriya]

Ah OK, no problem. I was thinking that it would be interesting to find out how successful a player is at catching "tough" chances (i.e. great catches).

Yes maybe not a bad idea to keep track of that as well.

 

[viriya]

Is that with or without keepers? Even 1 in 20 catches being great ones seems quite low, but who knows.

That's all together - haven't separated them yet.

That was the relatively rare case where they ****ed up.

It is not a rare case when they **** up though.

Now this is miles better, well done.

Is it easy enough to remove fielding off your own bowling or separate it? I know all fielding counts, but feel in ODI's the bowlers (particularly spinners) might be counted as miss-fielding off their own bowling harshly on occasions when they make quick ground, dive and just miss it which goes for 1 run down to the fielder at long on/off. That's the impression I get anyway when I see Dilshan, Ajmal, Yuvraj high up in the miss-fields.

 

[Athlai]

Yeah the results are looking better. But there's still more than a few outliers.

All three of them are up there because of their high drop rates. Even though they have quite a few misfields it's not that significant to make a big negative impression. In Dishan's case even though he has quite a few misfields his overall "Runs Saved" is net positive.

I'm still surprised about Dilshan and possibly Yuvraj - worth digging through the details for those.

One thing that makes me think I'm on the right track:

Kamran Akmal has been the worst keeper in Tests and ODIs in the past 8 or so years.. I don't think anyone would argue against that.

Also forgot to mention that I started tracking stumpings and added a new Stump Rate field when keepers are selected. I feel like I'm missing a lot of "missed stumpings" though.

 

[Athlai]

Kakmal at the bottom clearly a proof of concept.

 

[NUFAN]

Raina having so many more saves then others seems wrong. He is a fine fieldsman but I get the feeling the excited commentator uses better words for your parsing for him then others.

Also, on teams who don't field that well or have been dropping catches, a "well saved" is more likely to come up then clinical teams who are often saving runs.

EDIT - Steve Smith has never saved a run in his career? Which 26 matches did you use, he has played 51 matches..

 

[NUFAN]

This happens too often to make the saved runs feature difficult..

5.6
Hazlewood to Taylor, no run, bat closes in his hands again and square leg stops this incoming length delivery with a dive

9.6
Hazlewood to Root, no run, fine drive off a fullish one, but extra cover runs across and dives to his right to stop it

14.3
Maxwell to Root, no run, flighted delivery driven hard but cover stop it with a dive to his right

Saved runs is so hard to calculate.

Easier to calculate conceded runs. Wait for a misfield, see if any runs occurred due to it, mark those runs against the fielder.

You can then divide the total amount of runs conceded by the number of balls fielded by the fielder to get a value of many runs per ball fielded the player concedes on average.

You can also filter this information by fielding location to get more insight (misfields on the boundary will result in fours and thus more runs than misfields in the circle).

Good fielders will concede less. Bad ones will concede more.

 

[NUFAN]

You can then divide the total amount of runs conceded by the number of balls fielded by the fielder to get a value of many runs per ball fielded the player concedes on average.

You can do this going forward, but can't do this by viewing commentary. Also, think about how many non-eventual balls get fielded. It will make the stats misleading as no one should be rewarded for fielding a ball where the batsman didn't even contemplate running.

Yea I think any meaningful fielding analysis will need to be done using match footage and not text commentary.

I see your point, but some times fumbling an easy stop could lead to conceding a single. Kinda subjective I suppose, one would have to judge if fumbling that particular stop could lead to a run.

Yes misfields/great stops seem to be missing quite a lot of data. The issue here is the commentary doesn't identify the fielder all the time, and when they do it's mostly for bad misfields only.

The matches shown are the matches where Steve Smith had any fielding events. So in 25 of his matches he did "nothing" based on the parser (didn't drop a catch or take one, didn't misfield etc). I'm sure I'm missing data here, but runs saved/lost from ground fielding seems to be something that's hard to parse accurately. Dropped/great catches and direct hits are much more significant events though, so my guess is that it doesn't make a big difference when evaluating how good a fielder is.

I'm planning to go over the results more thoroughly next, so I'm sure with time the data will get better.

14.3
Maxwell to Root, no run, flighted delivery driven hard but cover stop it with a dive to his right

Yes this is exactly the issue that makes ground fielding hard to evaluate.

 

[viriya]

I already do this. As long as I can identify the fielder (which is not always possible).

Good point. It seems like the commentators are more likely to attribute the fielding properly when Indians are involved. Raina, Jadeja and Sehwag are all good examples. I think that's a fair conclusion to make.

Glad to see you did this.

Yeah unfortunately which makes it a bit difficult for you. Interested in how this would be rated by the way:

3.6
Shapoor Zadran to Anamul Haque, 1 run, fuller now, and edgy cricket all around. Bijoy hits it to cover where despite a dive from Sami Shenwari there should have been a single. Tamim doesn't want it, though. And the throw is wide but the first slip has not moved behind the keeper to back the throw up. And they get the single


So it was good fielding my Shenwari, then he through a little bit wildly and Bangladesh ended up getting a single from it anyway..
