BASEBALL: A.J. The Wild Man

A.J. Burnett has thrown a league-leading 23 wild pitches this year in 172.1 innings pitched, one of the grislier stats in an increasingly ugly season. How historic is that?

Well, among pitchers who have qualified for the ERA title since 1893 (the dawn of something like modern pitching, when the mound was moved back to 60 feet 6 inches), Burnett's rate of one wild pitch per 7.493 innings pitched would be the highest by a fairly significant margin:

Red Ames' 30 wild pitches qualifies as the post-1893 record. Needless to say, Nolan Ryan in 1981 is the only one of these guys to win the ERA title. (For curiosity - Sandy Koufax in 1958 would have made this list at #9 if he'd thrown just a few more innings). Among pitchers who threw at least 15 wild pitches but didn't qualify for the ERA title, here's the top 10; Burnett would rank 12th:

Stu Flythe1619362417339.3611413.0422932.45814.313

Mac Suzuki162001263319118.373895.8654287.39633.875

As you might imagine, this was the only season of Stu Flythe's major league "pitching" career; he was not one of Connie Mack's finer discoveries. Bobby Witt's near-legendary rookie season missed by just a few innings topping Burnett.

It would not be useful to chart the guys with higher rates from the pre-1893 era, when you had guys with no catcher's mitts or shin guards catching pitches thrown from 50 feet, often from a standing position several feet behind the plate. A few high points: Mark Baldwin threw the MLB-record 83 wild pitches (in 513.2 innings, one per 6.19 innings pitched) in 1889; Jim McElroy in 1884 threw 46 wild pitches in 116 innings, one every 2.52 innings pitched, the worst rate for anybody with 100 or more innings. A 19-year-old pitcher named Dan Collins threw 12 wild pitches in 11 innings in 1884; the only other guy to match that in more than 3 innings pitched was Rich Rodas, who threw 5 wild pitches in 4.2 innings for the Dodgers in 1983.

PS - A look at wild pitches on a per-pitch basis here. Funny fact: I saw a tweet linking to that a few days ago, favorited it (I have trouble clicking through links when reading Twitter from my Blackberry so I tend to favorite things to read later) and completely forgot about it until after I wrote this post and started getting a nagging feeling I'd seen something about Burnett's historic wildness before.

UPDATED after the season: AJ improved just a bit to finish with 25 wild pitches in 190.1 IP, still easily the record (one every 7.61 IP, or every 33.48 batters faced). In the postseason he added 1 more in 5.2 innings, facing 24 batters.

"Red Ames' 30 wild pitches qualifies as the post-1893 record."

Hey, let's not put any ideas into AJ's head . . . .

Then again, seeing if he can break the record maybe the only reason left for keeping my eyes open when he is pitching.

Surprised to see no knuckleballers here. Looked up Phil Niekro who is 7th on the all-time wild pitch list. Always amongst the leaders in wild pitches each year but he was also piling up 300+ innings and throwing 10-20 wild pitches. Wonder how many passed balls he caused.

I thought that also, but knuckleballers seem more prone ot passed balls because, I assume, the speed of the pitch is such that catchers have sufficient time to react enough to get their glove on the pitch.

Wasn't Jason Grimsley the pitcher who threw a ball at a fan who was hectoring him? It would seem he had the statistical basis for a defense of that claim.
