I decided to look at the swing and miss rates for the Royals starters since it is around the quarter point of the season. There has been some attention to the value of swing and miss rates, but I mainly just love seeing which pitches cause the big old whiff. Here is how the starters are doing so far in 2010 (league average has been around 19%):
| Name | Number of Swing and Misses | Total Swings | pitch_type | % of Swings That Miss |
| Meche Gil | 8 | 33 | CH | 24% |
| Meche Gil | 7 | 61 | CU | 11% |
| Meche Gil | 1 | 17 | FC | 6% |
| Meche Gil | 13 | 158 | FF | 8% |
| Meche Gil | 5 | 42 | SL | 12% |
| 34 | 311 | Total = | 11% | |
| Greinke Zack | 7 | 47 | CH | 15% |
| Greinke Zack | 3 | 32 | CU | 9% |
| Greinke Zack | 15 | 152 | FF | 10% |
| Greinke Zack | 15 | 59 | SL | 25% |

| Hochevar Luke | 4 | 24 | CH | 17% |
| Hochevar Luke | 5 | 27 | CU | 19% |
| Hochevar Luke | 16 | 56 | FC | 29% |
| Hochevar Luke | 13 | 112 | FF | 12% |
| Hochevar Luke | 4 | 13 | FS | 31% |
| Hochevar Luke | 11 | 90 | SI | 12% |
| Hochevar Luke | 16 | 46 | SL | 35% |
| 69 | 368 | Total = | 19% |
Here are the codes for the various pitch types:
FA Fastball
FF 4-seam Fastball
FT 2-seam Fastball
FC Cut Fastball
FS Split-finger Fastball
SI Sinker
SL Slider
CU Curveball
CH Change-up
Here is how they did from 2007 to 2009:
| Name | Pitch type | % Miss |
| Brian Bannister | FF | 11% |
| Brian Bannister | CU | 22% |
| Brian Bannister | CH | 23% |
| Brian Bannister | FC | 10% |
| Brian Bannister | SL | 13% |
| Brian Bannister | FA | 12% |
| Gil Meche | FC | 18% |
| Gil Meche | SL | 16% |
| Gil Meche | CH | 31% |
| Gil Meche | FF | 13% |
| Gil Meche | CU | 23% |
| Gil Meche | FA | 15% |
| Kyle Davies | CU | 26% |
| Kyle Davies | SL | 30% |
| Kyle Davies | FF | 10% |
| Kyle Davies | CH | 29% |
| Kyle Davies | FA | 12% |
| Luke Hochever | CH | 17% |
| Luke Hochever | SI | 14% |
| Luke Hochever | CU | 22% |
| Luke Hochever | FF | 11% |
| Luke Hochever | SL | 33% |
| Luke Hochever | FA | 9% |
| Zack Greinke | CH | 28% |
| Zack Greinke | CU | 27% |
| Zack Greinke | SL | 40% |
| Zack Greinke | FF | 11% |
| Zack Greinke | FA | 15% |
I don't have too much analysis, except that Greinke's slider went from one of the hardest pitches to hit last season in all of baseball, to below average this season.
