But the zero-inflated wild-pitch model makes a clear difference in category , improving the Spearman correlation on our blocking runs from .72 to .81 and the Pearson correlation from .57 to .87. Because those improvements come at no cost to the other measurements, these changes are a net positive and we will use them going forward. Especially when it comes to youth baseball — and especially for younger ages — keep it simple.
The results are then averaged, multiplied, and valued as with the catcher tabulations. Note that the pitch may be so wild that the catcher can’t control it, but a wild pitch won’t be scored if a runner fails to advance. Additionally, a “runner” could be either a player who moves from first, second, or third base OR a batter who advances to first on a strikeout .
A wild pitch is when a pitcher throws a ball so errantly that it gets past the catcher and allows the runner to advance at least one base. Sometimes the catcher may block a pitch, and the ball may be nearby, but he simply cannot find it for one reason swimg rail or another. When a wild pitch or passed ball goes through or by the catcher, or deflects off the catcher, and goes directly into the dugout, stands, above the break, or any area where the ball is dead, the awarding of bases shall be one base.

This is bad news for those who have become overly reliant on R’s handy “predict” function to specify all of their model predictions. Correct WOWY calculations involving intrinsic player characteristics require a coefficient by coefficient compilation of the baseline probabilities. In the R programming environment, the consensus choice is the pscl package, which efficiently tackles zero-inflation and hurdle models for data involving counts.
To pull a hitter is to substitute a pinch hitter for the next at-bat. To pull a pitcher is to take him out of the line-up and substitute a relief pitcher in his place. This is the same meaning as to yank a pitcher or use the hook. I need to check that out to see if it is the presence of the batter or the glove side of the catcher which is having an effect.

The example above is often scored as defensive indifference. The pitcher was throwing from the stretch, indicating he wanted to hold the runner on. A throw wasn’t made, but that’s only because the runner got a huge jump. Nolan Ryan is the modern era big leaguer who holds the record for the most wild pitches. The reason is due to how hard he threw every pitch, which helped him accumulate the most strikeouts of any pitcher in MLB history with 5,714.
However, if the runner advances because of the miscue then they will not be credited with a stolen base. As with many statistics, whether a pitch that gets away from a catcher is counted as a wild pitch or a passed ball is at the discretion of the official scorer. The benefit of the doubt is given to the catcher if there is uncertainty; therefore, most of these situations are scored as wild pitches.
If the pitch was so low as to touch the ground, or so high that the catcher has to jump to get to it, or so wide that the catcher has to lunge for it, it is usually ruled a wild pitch and not a passed ball. Because the pitcher and catcher handle the ball much more than other fielders, certain misplays on pitched balls are defined in Rule 10.13 as wild pitches and passed balls. Catcher defense is one of the more enigmatic areas of baseball study. It has developed relatively independently of other position player defensive analysis. This is probably because, although catchers field some ground balls and pop ups, their main defensive contribution is very different from that of all other position players. This contribution is mostly in preventing stolen bases, passed balls and wild pitches.
So, how many processes would you guess underlie a pitcher’s RA9? Well, given the graph, I think most of you would say “one.” What would that singular process be? Certainly there are other factors that affect scoring—ballparks, weather, opposing batters—but those are confounders, not processes. Rather, the runs-allowed process involves pitchers giving up run-scoring events, and all other things being equal, better pitchers give up fewer runs per 9 innings than bad pitchers. Why were our models still underestimating the value of pitch blocking?
Nolan Ryan is the modern-era leader in the wild pitches, throwing 277 over his 27 years in Major League Baseball . He also led his league in the category in six different seasons. However, the all-time record belongs to Tony Mullane, who threw 343 in the early years of the game from 1881 to 1894.
