I'm curious about all of this.
I like the more advanced stats and enjoy reading about them and looking at them. But, I can't say I'm intimately connected with them.
My impression is this: Dickey has pitched, really, really well since June. Then I see someone post that Dickey has essentially out-performed what should have been expected.
Which is fine. I look at stuff like that and think: "That's baseball." Before August, most of use would have argued that EE was having a below average year. Then he has this record setting month and suddenly his numbers are about where we expected.
But it makes me wonder, when he was really, really bad in April and May was he under-performing what was expected?
In other words, there's luck, there's bad luck and then there's pitching/playing to the level that was expected. I look at Dickey's overall numbers and figure he's about where I would expect him to be (maybe a little below, but with a month to go).
April-May: 2-5, 5.77 ERA, 5.69 FIP, 4.85 xFIP, 26.3 hard hit %, 23.2 LD%
June-August: 7-5, 3.36 ERA, 4.14 FIP, 4.79 xFIP, 22.3 hard hit %, 18.6 LD%
So basically
- the biggest thing here - Dickey has given up a lot less hard hit balls and line drives (and since the ASB that hard hit rate is <20%). This matches up pretty well with the eye test...even when the Angels hit him around they barely hit anything on the button
- HR rate is the one thing that will likely regress from the past little bit, but RA has actually been unlucky on balls in play, especially considering his hard hit %. That should even out. But knuckleballs are historically EXTREMELY volatile with HR rates based on the nature of the pitch. Its impossible to predict really.
The fact that his xFIP is the same for both samples says it all about xFIP for knuckleballers really...
Question (and I'm being serious, this is not sarcasm): have Dickey's numbers shown up uptick since the team obviously improved its defense?
I mean, having Tulo at short over Reyes, Revere in left over whatever the crap was out there before he arrived and Smoak playing a lot more at first, plus Goins having a regular role at second has to help all the pitchers - not just Dickey.
I shouldn't just apply the question to Dickey. It would also apply to Hutch. Buehrle and Estrada seem to be the kind of pitchers that pitch the same regardless of the D.
His BABIP up to the trades was .262 and it has been .307 in his last six starts since (which as noted above, is extremely unlucky based on the lower hard hit contact and line drive rates).
But there is a definite correlation between the improved defence and the improved pitching overall.
