In the scenario where a team chooses to end the half-inning early, the pitcher is allowed to start the next inning. The previous inning ended as if all three outs were achieved so the pitcher would start the next inning with nobody on base, no outs, and a fresh count on the next batter. That can lead to a lot of pitches by a pitcher and with nine innings of baseball traditionally played, how many pitches can a pitcher pitch in one game? MLB pitchers do not have a limited number of pitches they can pitch in one game.
Other baseball leagues, like Little League, will have a pitch count limit, but the pitch count limits vary from league to league. The record for the most pitches thrown in a single MLB game is pitches , set by Leon Cadore in To help younger leagues form their pitch count rules, the MLB has put together a guideline for youth and adolescent baseball leagues on pitch counts. Although this chart does not determine how many pitches can be thrown by each league, it does help leagues and parents know what a good recommendation is for how much a youth baseball player should be pitching.
MLB pitchers do not have a set limit of innings they can pitch in one game, but most MLB pitchers will pitch seven to eight innings on average. When pitchers are able to pitch for every inning of the game including any extra innings , they are awarded a Complete Game CG. I'm the owner of Baseball Training World.
I live in Denver, Colorado and I enjoy playing baseball on two different adult baseball teams in the surrounding area. During the course of a nine-inning baseball game, each team can easily throw over pitches.
Even though each team throws a lot of pitches, batters only swing at a limited number of pitches A followup exploration would explore the factors that affect pitch counts. Jim, This is great work! Do you have the raw data that I could see somewhere for like average pitches and innings pitched per start by team through the years?
This would be incredibly helpful. Dave: The Retrosheet play-by-play files are a good way to finding the number of pitches for each starter. Each plate appearance and pitches are recorded on each line. Some R manipulation is required. Hope this is helpful. You are commenting using your WordPress.

Introduction I just finished reading The Arm by Jeff Passan — it is an interesting description of the billion-dollar industry of pitching arms in baseball.
Do MLB teams generally stay within this pitch limit for starters? Has there been any change in pitch counts for starters in, say, the last 20 seasons? Is there much variability in the pitch counts for starters between teams?
One thing we noticed in an earlier post was that plate appearances are getting longer — that is, the average number of pitches per plate appearance has been increasing over recent seasons. Pitchers want to be efficient — that is, throw only a few pitches per batter. Can we identify some of the most efficient pitchers in the last 20 seasons? The Data Using Retrosheet play-by-play files, I collected the number of pitches thrown for each starter in each game for all games played in the seasons through This reflects the new strategy of opening the game with a reliever.
Although some teams seem to still average pitches, I see a general tendency for teams to have smaller than pitches for their starters. We see some interesting things. There is remarkable variability between teams which seems to reflect different opinions about the pitch limit. For example, the Colorado team only averaged Pitcher Efficiency Since there are more pitches in a game in current baseball, one should value the pitcher who can are efficient — throwing a small number of pitches per batter.
Geez, if Jamie Moyer played in he would actually lower the average players age by a little bit. Too funny. My guess is that now steroids are pretty much cleaned up at least for the moment that pitch counts will drop a bit. How come it's about I would love to find out how that happened.
Also, 12 I'd say this is proof that the hardball times estimates are incorrect. These are ACTUAL pitch counts; they had a formula for just estimating what the pitch count probably was based on walks, strikeouts, etc.
I'm pretty sure that the data in this post is correct because I double-checked it by using a second method.
On this page you can get the total number of pitches thrown in a season. In , it was , That came in games, as you can see here. Divide those two numbers and you get I checked this for a number of the years in the data above and they all matched up.
Isn't the higher overall pitch count due mostly to the increased propensity of managers to have a guy come in and face only a couple of batters? So instead of having two or three pitchers in a game, you now have four or five, each fresh when he comes in and perhaps more likely to throw more pitches than if the starter had remained in.
Or maybe I'm just making stuff up. Dan, why would a fresh pitcher be more likely to throw more or fewer pitches than the starter? Maybe the starter's fastball is a little slower late in the game, and with fewer swings and misses, balls get put into play more often. I don't think the number of pitchers used in the game has much affect. I can't imagine any other circumstance where anyone could lead both leagues, in any major, non percentage category in the same year.
Good article. Thanks for all the data. What impressed me is how consistent the numbers are. Plate appearences per game have stayed pretty close to 38 for the past century. If the estimations in one of the other replies for pitch count since are reasonably close then pitch count looks pretty stable too.
Even in your chart the significant break looks like 93 to 94, and stable since Makes sense to me that pitch counts are on the rise Not so sure it's about the use of pitchers, though. And most figured a walk was something the pitcher did. Today, OBA and walk rates are right at the centre when a hitter's skills are considered, even in the GM's office.
Listen to a ball game today, and you will often hear announcers extol the virtues of the selective hitter. None of them were doing that in the s and s. Mike Hargrove, the Human Rain Delay, would not be noticed in today's game.
I almost hate to bring up Boston - New York, but it's always there in those games. These teams have succeeded with what is clearly a conscious strategy to make the opposition pitcher work. Success gets imitated.
