The guy on the mound was not a guy that was notorious for striking guys out. So we made the pitching change with two strikes and we ended up striking the guy out. Other coaches have developed the idea independently. In , D. Dan Heefner, head coach of Dallas Baptist, says he joined the cult of the mid-PA pitching performance almost by accident.
Heefner, like Cohen, is a former pro hitter , so he also understands the mental effect of the waiting period while the new pitcher enters, which he likens to calling a timeout to faze a field goal kicker. Duke, Arkansas, and other high-profile programs have gotten in on the act, which raises an obvious question: How often is this actually occurring across all colleges?
That turns out to be a peskier question to answer than one would think. NCAA play-by-play data rarely, if ever, accurately records instances of the mid-PA pitching change; instead, pitches thrown within the same plate appearance by the second pitcher are also attributed to the first, making examples of the tactic impossible to identify.
However, only of those came in two-strike counts. The leaders in two-strike-count cases: Mississippi State and Kentucky, at nine and eight, respectively. From to , TrackMan systems were installed in fewer than 10 parks per season, gradually ramping up to 54 in Those results must include many cases in which a pitcher was pulled because of injury or fatigue, not for strategic reasons.
Shaky as our intel is, we can say with some confidence that college coaches are making mid-PA changes much more often than major league managers, who seem to do it only out of necessity or, rarely, for the Girardi reason. The same TrackMan method unearths 94 MLB cases from to —roughly a tenth of the college count, in many more games.
Because of a coding quirk, Retrosheet records contain only 25 identifiable examples from to , while a search of the Pitch Info database at Baseball Prospectus , relying on differences in release point rather than human input on who was pitching, flags from to Not only do these methods disagree with each other, but each of them is missing confirmed cases.
He walked the hitter he inherited, but struck out the next one to preserve the slim lead. Despite the lack of MLB precedents, though, we do have data that suggests this should work. In The Science of Hitting , Ted Williams stressed the importance of seeing pitches, arguing that a long first plate appearance could pay dividends for the rest of the game.
He was right. Not only do hitters gain ground each time they face the same pitcher within the same game—thanks more to familiarity than to pitcher fatigue—but their degree of improvement depends on how many pitches they see. One Baseball Prospectus study showed that hitters who saw four or more pitches in their first plate appearance improved 2.
Granted, hitters may glean insights into opposing pitchers between plate appearances, via tips from teammates or coaches or their own observations from the dugout or on-deck circle. It stands to reason, then, that a hitter would be better equipped to deal with a pitcher toward the end of a plate appearance than he is at the beginning. As the predominantly above-average outcomes past the six-pitch mark confirm, long plate appearances tend to favor the hitter.
Another image from Judge demonstrates the intra-PA familiarity effect even more clearly. This one displays the difference in hitter success rate on each successive pitch on the same two-strike count, lumping together , , , and counts and again controlling for the identities of the hitter and pitcher. For more evidence, we can study how hitters behave. This season, the leaguewide swing rate on first pitches when the batter is in his second or greater time through the order and the pitcher is also in his second or greater time through the order—that is, when the two have already clashed in the game—is But the leaguewide swing rate on first pitches when the batter is in his second or greater time through the order and the pitcher is in his first time through the order—when the hitter has already batted in the game, but against a different pitcher—is only The difference is even more pronounced on first pitches in the strike zone: A relief pitcher shall not be held accountable when the first batter to whom he pitches reaches first base on four called balls, if such batter has a decided advantage in the ball and strike count when pitchers are changed.
All of it hinges on whether at the time of the pitching change, the batter has a decided advantage, based on the count. Yours in baseball, Rick. Average Rating. Click here to add your own comments.
