  2. Cum Drop

    Comment by McWisdom — April 17, 2013 @ 2:07 pm

  3. Oh…I honestly didn’t even think of that. I guess I could change it to total drop…

  4. I’m so sad that I showed up after you changed it.

  5. You people have sick minds :)

  6. I started reading it and burst out laughing at work, made my day.

    Now it’s dull and boring again. I demand you change it back!

  7. Jackson is a G. (No offense Miguel, Prince, or Verlander)

  8. Thank God I got a screengrab of that.

  9. I’ve never understood this about Pizza Cutter’s “stabilization” methodology.

    The author compared even-numbered PAs to odd-numbered PAs. He didn’t compare first 50 PAs to next 50 PAs for example. He gives legitimate reasons for taking this approach but my problem is this:

    When applying this data to the real world, you simply cannot say that a metric stabilizes at X PAs — because in reality we are always looking at a player’s FIRST X PAs, meaning consecutive PAs within a single season, which Pizza Cutter’s methodology didn’t evaluate. Not only that, but the author took 2-year data to ensure he had enough PAs.

    That methodology is fine but then why does the sabre community always make statements like those made in this article: “Swing percentage stabilizes around 50 PA, and contact rate between 70 and 100 PA”.

    No they don’t… at least not in the way that this article describes. Swing percentage stabilizes at 50 PAs consisting of every other PA (therefore 100 total PAs) compared to 50 PAs inbetween. And of course, comparing PAs in this way introduces far more stability than comparing 2 groups of consecutive PAs, since certain factors are being held constant (often the same pitcher on the mound, weather, ballpark, defense and so on).

    It’s interesting data but it cannot be practically applied in the way that it’s routinely touted.

  10. “Jackson is only swinging and missing 2.7% of the time, a number that would put him in the top 20 since 2002 (which is as far back as we have that data). Ditto with his 92.3% contact rate.”

    Can anyone explain to me how you can have swing and miss 2.7% of the time but only have a 92.3% contact rate? Shouldn’t these two numbers add up to 100%? What am I missing? Thanks in advance.

  11. I traded Miley and Maybin for Jackson just before the season started . I’m feeling pretty good about that trade now .

    Comment by Dirck — April 17, 2013 @ 3:06 pm

  12. Interesting and relevant! Cool story!

    Comment by davisnc — April 17, 2013 @ 3:12 pm

  13. foul balls dont count towards contact rate but do count toward swing and miss? maybe?

    Comment by Florko — April 17, 2013 @ 3:30 pm

  14. The denominator for SwStr% is all pitches (seen by that batter).

    The denominator for contact% is all pitches swung at.

    Comment by Ryan — April 17, 2013 @ 3:38 pm

  15. I believe that foul tips are counted as swinging strikes but not as contact.

    Comment by Jakerrr — April 17, 2013 @ 3:41 pm

  16. nobody cares.

    Comment by Sleight of Hand Pro — April 17, 2013 @ 3:46 pm

  17. Jackson gave all his K’s to Rick Ankiel

    Comment by Hurtlockertwo — April 17, 2013 @ 3:55 pm

  18. ?(drop) would work too if you’re trying to stay geeky and keep columns narrow.

    Comment by joser — April 17, 2013 @ 5:19 pm

  19. Or maybe not. We don’t support HTML character entities for greek letters here? Σ

    Comment by joser — April 17, 2013 @ 5:20 pm

  20. All your K’s are belong to us!

    Comment by Rick Ankiel — April 17, 2013 @ 6:04 pm

  21. Jackson’s elite BABIP skills and 20 homer power coupled with this potential improvement in K rate? Yikes. If this contact improvement isn’t noise, he’s got to be the most likely to have a .400 season of anyone playing now.

    Comment by The Party Bird — April 17, 2013 @ 7:51 pm

  22. Thanks Ryan.

    Comment by Johnny Come Lately — April 17, 2013 @ 8:11 pm

  23. …basically, he’s got a realistic shot at having what tigers fans long ago hoped would be ron leflore’s career. only better.

    Comment by deafdumbandblindkid — April 17, 2013 @ 9:17 pm

  24. If there’s one thing worse than people talking about fantasy ball on Fangraphs comments, it’s the people who needlessly ream them for it.

    There’s no need for all the attitude.

    Comment by Bret — April 17, 2013 @ 9:49 pm

  25. you and i have different versions of “attitude”

    Comment by Sleight of Hand Pro — April 17, 2013 @ 9:52 pm

  26. I vote for Natitude

    Comment by Natman — April 18, 2013 @ 12:25 am

  27. Will the Curtis Granderson for Austin Jackson AND Max Scherzer, Phil Coke, (and) Daniel Schlereth trade come up as best trade of the decade in 2020?

    Comment by Dave Dombrowski — April 18, 2013 @ 12:37 am

  28. in the article written in 2020.

    Comment by Dave Dombrowski — April 18, 2013 @ 12:38 am

  29. Well of course, he would strike out four times the day this article would be written.

    Comment by James — April 18, 2013 @ 1:51 am

  30. Lifting his 2013 strikeout rate from 7.5% to 12.2%! Maybe Austin and the Tigers just hadn’t faced many pitchers like Felix, Felix, Capps and Furbush.

    Comment by Jon — April 18, 2013 @ 2:45 am

  31. what’s confusing to me is that Jackson seemed to be striking out 3 times a game in the spring (swag) especially in the last 2 weeks before the season. Further evidence that spring stats doesnt matter?

    Comment by hp — April 18, 2013 @ 9:32 am

  32. No mention of the change in his approach at the plate starting in the spring of 2012…? What about the fact he stopped using a major legkick last year? I really like the use of statistics, but numbers without context or reasoning results in a lacking article.

    Comment by ron paul — April 18, 2013 @ 11:42 am

  33. That was a really well-said, well-thought-out comment; genuinely appreciate it, Jake. Would be interested to see if it merits a response or discussion from any of the authors who cite K-rate stabilization rates.

    Comment by Jason B — April 18, 2013 @ 3:22 pm

  34. That is track five…it is called “attitude”.

    Comment by M Hedberg — April 18, 2013 @ 3:23 pm

  35. Yup.

    Comment by Grant — April 19, 2013 @ 2:11 am

  36. AJ is now batting .272 and striking out more than once a game..He’s back to being a strikeout king…It was only a matter of time before he showed his true colours…That trade for Coke and AJ isn’t looking very good right now is it?..I’d rather have Granderson who will have a superior career.

    Comment by Tedd — May 15, 2013 @ 11:41 pm

  37. slight exaggeration..He has 33 SO’s in 34 games…It’s gonna get worse,trust me.

    Comment by Tedd — May 15, 2013 @ 11:45 pm

  38. I heard you boys talkin bout me. Austin Jackson ain`t got shit
