youth gone wild

Kaz Ishii, who turns 32 next month, is nearly 3.5 years older than the average Biggio plunking pitcher - 28.5. Biggio has been hit most often by 26 year old pitchers. However, rather than 26 year olds being more likely to hit batters than other aged pitcher, this is probably most likely due to the over abundance of 26 year old pitchers in the league. During Biggio's career (through '04) 26 year olds have thrown 65,548.67 innings, trailing only 27 year olds.

The leaders, age 22 at 0.0274, only hit batters about 29% more often than the most infrequent plunking ages (excluding ages at which less than 20 players pitched).

During Biggio's career it has been the older pitchers who have been hitting batters most frequently. The 45 and 46 year old groups are heavily skewed by Nolan Ryan and Charlie Hough, but the 18 pitchers who pitched at age 42 hit 70 batters in 1571.33 innings - 45% more often per inning than the 30 year olds.

Craig Biggio has been hit 55 times by pitchers older than him, and 214 times by younger pitchers.

Note: for pitchers who hit Craig Biggio with a pitch I used actual age of pitchers on the date they hit Biggio, but for historical plunk data I used the age the season during the year in which they turned a given age (season minus birthyear), so players who turned 28 in December were consider to be 28 for the season. Because it was easier.

Surely Excel would let you do a standard deviation for some of those?

Plunk number 270, leading off the ninth inning in the BOB. Not enough to win the game, though.

Now if you ask me, and plenty folks do now and again, sometimes my prognostications come just a tad early, like when I suspected that Javier Vazquez was going to be guilty of hurling the 270th plunk at our man “Target” Biggio. Well, I was wrong. I like to be the first one to admit that I am wrong because if I don’t, then Mama sure as heck will. She likes to jump in there and point out each and every time I get the least little detail wrong… such as the pitcher guilty of the 270th. I got the city right, and the month right, and I reckon that ought to count for something.

Anyhow, this here José Valverde was the man. Now if you use the patented Cletus J. “Bubba” Huckabee Anagram Generator (version 3.4a, aka “the grits and gravy version”…which I have mentioned previously) you will see that the same letters that make up the name José Valverde also spell out “JADE REVOLVES” and that should have been the hint that clued me in to the fact that Señor Valverde was going to be the guilty one.


Now, I am still mystified, as I am sure many of you are, that “Javier Vazquez” also spells out… “VIVA JAZZ QUEER” and that looked to me to be a sure sign of plunkiness, but this time he wasn’t guilty of the act… so apologies to Señor Vazquez, the Pride of Ponce, Puerto Rico.
