  1. Speaking as somebody who watched him play all year, Bourn ventures into RF and especially LF (covering for Lee) constantly. I don’t know how UZR handles that, as well as the gigantic CF in Minute Maid Park, but those two things together make me skeptical of his rating, which looks low in comparison to what my eyes tell me. The guy can really run, needless to say.

  2. I would suggest that the placement of Bourn and Pence on the list would indicate that the Houston outfield is doing a fair job at limiting the liability caused by having Lee in LF.

  3. You should do it based on “team chances” while the fielder is actually on the field.

    Considering that you have 3 OF, then the average would be 33% (say 40% for CF and 30% for the corners). So, this chart is very misleading, when your #15 guy has 30% of team chances, but is a CF.

  4. This may be a stupid question, but I assume it is a good thing that these guys are able to get to such a large percentage as centerfielders. Is that correct? Is it more complicated than that? Would this do anything to warp UZR and other fielding metrics? (I am a bit ignorant as to how they are formulated)

    Comment by Garrett — December 21, 2009 @ 10:15 am

  5. To add to Tango’s post above, in 1999 Jones played CF in 98.4% of his teams total innings. In contrast in 2009 Kemp played CF in only 91.9% and Bourn 92.7%.

    Comment by Peter Jensen — December 21, 2009 @ 10:39 am

  6. Especially because Jones played just 119 games in 2009.

  7. Do outfield chances include outfield fly balls fielded by infielders on the outfield grass or is it just the sum of all the chances of the outfielders combined?

    Comment by Matthew Nolan — December 21, 2009 @ 11:39 am

  8. Sorry to be ignorant but is it Franklin Gutierrez?

    Comment by Matt — December 21, 2009 @ 12:12 pm

  9. I imagine that next year’s list will include Colby Rasmus, he’s already regarded as one of the premier defensive CF, and can only get better(especially if he’s healthy).

    If TLR played him everyday, the metrics would probably bear that out.

    Comment by Tim G — December 21, 2009 @ 12:21 pm

  10. Yup. I believe Dave Neihaus gave him the nickname (though Gutierrez was not the first player to be called Death to Flying Things).

    Comment by Teej — December 21, 2009 @ 12:27 pm

  11. Raul Ibanez only had a 20.6% usage rate last year. Granted he was lifted for defensive replacements frequently, but still, might have helped pad that 10.7 UZR/150.

    Comment by Rut — December 21, 2009 @ 12:30 pm

  12. There’s a link in there somewhere.

    Comment by Teej — December 21, 2009 @ 12:30 pm

  13. Raul wasn’t lifted for defense that much from my observation, except for a short time when he returned from the DL.

    Not so sure why it is called “ball hogging” if the team sets their outfield play this way and has a hierarchy for which fielder gets to call for the ball.

    Comment by neuter_your_dogma — December 21, 2009 @ 3:38 pm

  14. I don’t understand the point of this data. Wouldn’t teams be happy to have their best fielder (usually the CF) taking the most outfield chances. I don’t understand how a “ballhog” label would arise. It’s not like basketball where one player dominating the ball could take away from other players’ effectiveness. If I have Franklin Gutierrez in CF and Milton Bradley in LF, for example, I’d want Gutierrez to make an attempt on anything he can get to even if he walks right in front of Bradley.

    Comment by GBeck15 — December 21, 2009 @ 4:56 pm

  15. In my interpretation it seems that the main objective of this post was to note how unusual a season Jones had in 1999 without necessarily attempting to explain the reasons behind that outlier 45% data point.

    Excellent individual defensive skills in the outfield are likely to contribute, but certainly there are other factors, as well – hence, Sosa’s 416 chances in ’99. It’s good to see the comments run out some theories as to what drives this statistic (poor play by fellow outfielders? hierarchy of who “takes charge” on flies? tendencies of the pitching staff? home park?), but it doesn’t seem at the moment that anyone has a handle on what underlying factors drive “usage %.”

    Comment by Ben — December 21, 2009 @ 5:27 pm

  16. That makes more sense to me, I guess I got hung up on the ballhog aspect, even it wasn’t the purpose

    Comment by GBeck15 — December 21, 2009 @ 5:37 pm

  17. Well Bruntlett, Dobbs, Francisco, and Stairs picked up the other 13.37% chances, so that’s a decent amount.

    Comment by Rut — December 21, 2009 @ 6:44 pm

  18. I was bored and actually looked a lot deeper into this.

    Here I give my explanation what I basicly did. I thought there were some issues with what you brought up:

    1. Playing time adjustment
    2. Positional adjustment
    3. A scale

    Solution for first issue:
    I took every chance – of let’s say a CF – and divided them by te teams total chances for that position (here CF). I called that number CH%. In the next step I did exactly what you did (dividing the players chances by total chances of his teams complete outfield) EXCEPT adjusting that number by dividing it by CH%. Imagine a player with 450 chances at CF and his teams total chances at CF are 500 he would have a CH% of 90.00. Now lets say his teams complete outfield had 1100 total chances. Now you do this (450/1100)/90%=45.45%. I will talk about that number later on.

    Solution for second issue:
    Like Tango said, you cant compare apples and oranges. Just do all the stuff I talked about above for each individual outfield position and generate 3 seperate scales/graphs whatsoever.

    Solution for third issue:
    Here I am – not quite but almost – quoting Tango again. He said the distribution would be LF/CF/RF – 30%/40%/30%. I calculated the exact numbers for the 2009 season. They were 29.84%/39.06%/31.10%, respectively. There you have your scale to evaluate above or below average performance. This is the point where I bring up the number to be talked about later. It was 45.45% USAGE for our CF. As you can see he did quite well.

    In the next post I am going to showcase the Top 10 and Flop 3 at each outfield position (min. 1000 Inn. played at that particular position). And maybe a correaltion between my numbers and UZR and RngF.

    Oh.. and if there are any mistakes in grammar or with words be cool man! I am native German and this is not my motherlanguage. Peace

    Comment by AC_Butcha_AC — December 21, 2009 @ 7:48 pm

  19. I will do Top5 and Flop5 since there are just not enough for a Top10

    Comment by AC_Butcha_AC — December 21, 2009 @ 7:51 pm

  20. Let’s say Top5 and Flop3 THAT’S IT NOW LOL

    Comment by AC_Butcha_AC — December 21, 2009 @ 8:26 pm

  22. Hey I don’t know about all of these but the Raul Ibanez numbers are off. There were 28.62% of chances taken by Philadelphia outfielders not named Victorino and Werth, but only 20.59% were chances for Ibanez.

    Comment by Rut — December 21, 2009 @ 11:00 pm

  23. On a different note: Will you be doing a 2009 FIP+ like you did for beyondtheboxscore last year ? Would be nice.


    Comment by OPS2000 — December 22, 2009 @ 6:33 am

  24. Homer here! The Ichiro flop designation is ridiculous, considering that it looks to have statistically insignificant difference vs. league average.

    Comment by micahjr — December 22, 2009 @ 8:21 am

  25. Suzuki’s CH% is actually lower–25.99% or (326/1254) x 100. But, given that AC_BUTCHA_AC’s numbers are off, I’m not sure his league averages are right.

    Comment by Rut — December 22, 2009 @ 9:17 am

  26. hey rut,
    you are right with Ibanez numbers. I was a bit tired yesterday so there are some mistakes.

    Ibanez has a 27.49% Usage in LF.
    All Phillies LFs have a Usage of 28.62%

    But that is not only the case with Ibanez. Actually every number you see above is the teams Usage for that position. I worked on it.


    A Rightfielder has had 300 chances. His team had 350 chances for all players in RF.
    We know this years distribution was 29.84%/39.06%/31.10%. Our RF missed 50 chances. Given the average outfield usage for that year, how many chances would have had the other two outfielders. They would have had roughly 104 chances (103.917).
    Now let’s say his team had 1200 chances overall in the outfield. Subtract the average total of chances when he didn’t play from that number and you get about 1096 chances (1096.083).

    300/1096 = 27.37% Usage, while his team RF usage was 29.17%.

    Comment by AC_Butcha_AC — December 22, 2009 @ 9:18 am

  27. well my LgAv numbers are definately right. My numbers above were off, because of a different mistake.

    Oh and Ichiro hadn’t 26.00% Usage because you can’t calculate it that way. He hasn’t played every chance on RF for the 09 Mariners. He had 326 of the 366 RF chances. So he missed 40 chances. As explained above I now calculated the average chances his outfield fellows would have had during 40 RF chances. NOw you can subtract that from the actual OF chances. Divide Ichiro’s 326 chances by that number and you find him at a 28.83%.

    Comment by AC_Butcha_AC — December 22, 2009 @ 9:28 am

  28. AC_Butcha_AC,

    I’m confused. If Ichiro had 326 chances out of the total 1254 outfield chances then he had a 25.99% usage rate. A crucial point of this article is that there aren’t “right field chances” and “center field chances” there are just fly balls that outfielders get. Ichiro happened to only get 326 of the total fly ball chances for the Mariners last year.

    Comment by Rut — December 22, 2009 @ 9:39 am

  29. yeah but the point is: corners are just getting about 10% less chances. That is that apples oranges thing i wrote about. Of course, you are not getting the same amount of chances like a CF when playing left. So your usage will be less.

    Imagine a LF usage of 35% which would be pretty good. And a well below average CF has a usage of 37% let’s say. You can’t blame the LF for just getting less chances. But you could credit him with about a 5% usage above an average LF, while the CF here is about 3% below average.

    that is my point here. Compare apples to apples
