  1. Jamie Moyer: 48.2 IP, 14.7% IP, 7.4% BB.. you mean 14.7% K, right? % IP sounds like a fun stat. % of team’s innings pitched?

  2. I would have liked one of the Daily Notes to acknowledge Daniel Hudson’s return.

  3. Fifth best (lowest) SIERA, right?

  4. Indeed! Edited duly!

  5. 95 wRC+ is good for 6th/16 and league average is 93. So doesn’t that count as slightly above average?

  6. Gio led the minors in back to back years in K’s. If he keeps his walk rate down (big if) he’s an ace.

  7. That’s what the White Sox, Phillies, White Sox, A’s and Nationals all have hoped.

  8. ““Per PITCHf/x, Gonzalez is throwing the same pitches as in 2011 at basically the same rates.”

    The Chi-squared stat on the differences of those rates is 50.04, which has a p-value of 7,8165×10^-11. That hardly seems like the same rates.

  9. the pitcher rankings are off if yu and jamie are that low, there needs to be some novelty area of the pitcher formula.

  10. He’s throwing his fastball 7+ percent more this year. That hardly seems to be insignificant…

  11. I agree. The age curve should have a curve up at the tail, like the nike swoosh. And mysterious imports from the Orient need their own category.

    Can “knuckleball factor” be changed to “arbitrary, but universally acknowledged to be interesting, novelty factor”? (ANT-uatbi)

  12. Wasn’t it practically predicted that Gio Gonzalez would be sort of Oliver Perez Part II and the A’s got the better deal with the prospects they got?

  13. I dislike the lack of sample size here. I’m not saying you’re obfuscating the truth, just that I’d like to know that Gio’s thrown 877 pitches. 7% change is what, 60-ish pitches? One offspeed pitch per inning in 2011 turned into a fastball in 2012.

    Pitch values say that his fastball has gotten a LOT better. They also say that his changeup has gone from being not very good to being quite good. I can imagine you could make an argument that a better fastball = more fastballs = better change, but why would his fastball be better to start with?

  14. 2.4% HR/FB. Totally sustainable, you guys.

  15. With Gio’s current rate stats, he’s still easily one of the best pitchers in baseball when that regresses.

  16. Isn’t it May 28th?

    Comment by Undocorkscrew — May 28, 2012 @ 3:34 am

  17. Except for one smart lad who stated in his analysis of the trade that Gio was underrated and Oakland did not get enough for him.

  18. Obligatory percent/percentage point correction:

    Comment by Elias — May 28, 2012 @ 3:39 pm

  19. One thing that sticks out about Gio’s K rate this season is how much it is aided by facing opposing pitchers. Following the Atlanta game he has recorded k’s on 15 of 19 PA against opposing pitchers (plus 2 sac and 2 GO). Maybe there’s something about his stuff that dominates non-mlb level hitters.

    Comment by John C — May 28, 2012 @ 4:17 pm

  20. Adding onto that his k% falls from 32.4% to 27.1% if his PA against opposing pitchers are disregarded.

  21. You guys beat me to the punch. I was about to ask what you guys just said. Good job.

    Comment by Antonio Bananas — May 28, 2012 @ 4:50 pm

  22. I’m confused, don’t other NL starters see pitchers at the plate too? If striking them out is so easy, why don’t the other starters just do that?

    Comment by monkey business — May 28, 2012 @ 8:12 pm

  23. So, after this start the K rate is up to 32.4%. Yes, it is one start, but when a player is way off the map, the decline tends to be very fast.

    I’m not saying he will end the year with a 32.4% K rate, but I wouldn’t be surprised to see him end in the top five, since everyone at the top will likely see a decline (regression and all).

    Comment by monkey business — May 28, 2012 @ 8:16 pm

  24. Edit: k% falls from 32.4% to 28.4%

    Comment by John C — May 28, 2012 @ 8:39 pm

  25. Which is an interesting stat…because an increase to 32% from 24% doesn’t look sustainable…but from 24% to 28%? That’s a bit less likely to regress.

  26. I like the concept, but not the designation of the variable. How about ARBUNI (Arbitrary Universal)?
