Mound Visits and Pickoff Limits: The Rules That Speed Up the Game
How major-league baseball limited mound visits starting in 2018, tightened the cap in 2019 and 2024, and added a limit on pickoff throws and step-offs in 2023, with worked examples of each rule.
For most of baseball's history, a manager could walk to the mound as often as he liked, a catcher could jog out to talk with his pitcher between any two pitches, and a pitcher could throw to first base until the runner or the crowd gave up. None of that was against the rules, and all of it takes time. Over a series of changes, in 2018, 2019, 2023 and 2024, Major League Baseball turned these habits into a budget: a fixed number of mound visits per game, and a fixed number of pickoff throws and step-offs per batter.
The point of the changes was pace of play, and they were part of a larger package. In 2023 the same rule set that capped pickoffs also introduced the pitch clock, larger bases and limits on defensive shifts. The details below describe the rules as they stood through the 2025 season. Rules at this level are revisited every winter, so check the official rulebook and the league's current announcement at mlb.com before you rely on a number, especially if you are using this page to settle a dispute.
This article explains each rule in the order it arrived, defines what counts and what does not, works through concrete situations, and then looks at how the limits changed strategy. It leaves out exact game-time averages, which are best taken from the league's own data.
How mound visits worked before 2018
The old system had two layers. The first was a rule aimed at managers and coaches: a manager or coach could go to the mound to talk to a pitcher, but a second trip to the same pitcher in the same inning meant that pitcher had to be removed. That rule was old and rarely invoked, because a manager who wanted to talk twice in an inning usually just made the change.
The second layer was the players, and for them there was essentially no limit at all. A catcher could go to the mound, and so could an infielder, and the umpire's only tool was to tell them to get back. In practice the umpire would let a conference run for a while and then walk toward the mound, a gesture everyone understood. A runner on second base made visits more common, because that runner could see the catcher's signs and the battery needed to agree on new ones.
The visits were not a scandal, but they were a piece of the game's idle time. Each one stopped play for as long as the participants chose, and in a game with several of them the time added up. Every visit also broke the rhythm of the plate appearance, which is why the league treated them as a pace-of-play problem. That is the background to 2018.
2018: six visits per nine innings
Starting with the 2018 season, each team was limited to six mound visits per nine-inning game. The count was per team, not per pitcher. A team that went to extra innings received one additional visit for each extra inning, so the budget grew as the game did, and unused visits did not carry over from game to game.
In general terms, a visit was counted when a manager or coach went to the mound to talk to the pitcher, or when a fielder went to the mound, or the pitcher left the mound, to confer. The umpire kept a running count and told the managers when a team had used its last one.
Some trips were not charged. A visit that ended with a pitching change was free, because the manager was going out to take the ball. A visit to check on an injured player was free too. The rulebook lists a few other narrow exceptions, and its text controls over any summary here.
The practical effect of the cap was that a team could not talk its way through a crisis in the eighth inning if it had already spent its six talking in the third. The rulebook sets out what happens to a team that goes out anyway.
2019: five visits
For 2019 the limit was cut from six to five per nine innings, with the same extra-inning allowance. It was a small adjustment that showed where the league was heading, and it forced teams to think harder about which innings deserved a conference.
2022 and PitchCom
The tool that changed the underlying reason for most visits arrived in 2022. A common cause of mound trips had been sign confusion: with a runner on second base who could see the catcher's fingers, teams needed to change their signs, and the quickest way was to walk out and agree on a new set. In 2022 the league approved an electronic system called PitchCom, a device that lets the catcher call pitches by pressing buttons on a wristband, with the pitcher hearing the call through a receiver, in his cap. It reduced the need for the sign-change visit. The system is optional, and teams can still use fingers.
2023: a pitch clock and a pickoff limit
The 2023 season brought one of the largest sets of rule changes in decades. The mound-visit limit stayed at five per nine innings that year, and the change that mattered was the pitch clock: the pitcher must begin his delivery within a set time after receiving the ball, and the hitter must be in the box and ready with a set amount of time left. In 2023 the clock was 15 seconds with the bases empty and 20 with a runner on base. A pitcher who violates the clock is charged an automatic ball, a batter who violates it an automatic strike. For 2024 the league cut the runners-on time to 18 seconds and, in the same winter, lowered the mound-visit limit from five to four per nine innings, again with one extra visit for each extra inning. Check the current rulebook for the exact numbers, because the league has adjusted them before.
The clock created a loophole that the same rule set had to close. If the only thing resetting the clock was a step-off or a pickoff throw, a pitcher could reset it indefinitely. So the rule set added a limit on what the league calls disengagements.
The pickoff and step-off limit, in detail
A disengagement is a pickoff throw, or a step-off from the rubber after the pitcher has begun his set. A pitcher is allowed two disengagements per plate appearance. If he makes a third and does not get a runner out, he is charged with a balk and each runner advances one base.
The key phrase is "does not get a runner out." The third attempt is not forbidden; it is a gamble. If the pitcher throws to first a third time and the runner is tagged out, there is no balk, because the point of the rule is to penalise repeated attempts that do not work. If the throw is wide, or the runner dives back safely, the balk is called and the runner is awarded second. A third step-off can never retire anyone, so it is always a balk.
The count starts over when a new batter comes to the plate, and it starts over if a runner advances during the plate appearance, for example on a stolen base, a wild pitch or a passed ball. The count belongs to the batter and not to a particular runner, so with runners on first and second, two throws to first and one to second together use all three.
Worked examples
Example 1: the simple case. A runner is on first with nobody out. The pitcher steps off once to disrupt the runner's timing, then throws to first once. That is two disengagements. If he throws over again and the runner is safe, he has balked and the runner goes to second. If he steps off a third time, it is a balk whatever else happens.
Example 2: the reset. Same situation, but after the second pickoff throw the runner breaks for second on the next pitch and steals the base. The steal is a runner advancing, so the count starts over for the rest of the plate appearance, and the pitcher has two fresh disengagements to use on the runner now at second. The runner who is willing to go on the pitch after the pitcher has used up his attempts is the one the rule helps.
Example 3: two runners. Runners on first and second. The pitcher throws to second, then to first. Both count toward the same limit of two. A third throw to either base, if it fails to retire a runner, is a balk and both runners advance.
Example 4: the timeout. The limit is aimed at repeated attempts to hold a runner, and time called for an injury or by the umpire is a separate matter. Batters have their own limit: one timeout per plate appearance, and a batter who is not ready when the clock runs down is charged an automatic strike.
What the limit does to a running game
The limit is arithmetic, and the arithmetic favours the runner. A pitcher who has used two disengagements knows that a third can only help him if he is certain he can get the runner. That gives the runner a bigger lead, because the cost of a bad lead is lower, and on the next pitch the runner can go without fear of another throw. Managers noticed immediately. The result, widely reported in the first season of the rule, was a sharp increase in stolen-base attempts and in the success rate of those attempts, compared with the seasons before.
Pitchers had to adapt. The common responses are easy to see in the rules: a quicker delivery to the plate, because the clock already forbids long holds; saving disengagements for the moments when a steal is most likely; and varying the time spent in the set position within the clock.
Catchers and middle infielders faced new demands as well. With the pickoff less available, the throw from catcher to second base had to carry more of the deterrent weight, which raised the value of a strong, accurate arm behind the plate. Left-handed pitchers, who face first base, arguably lost less than right-handers, because they can hold a runner on first with their stance.
Managing the four visits
The visit limit is a much simpler budget. A team has four visits in a nine-inning game and, in practice, the question is when to spend them. A club might decide to keep one or two in reserve for the late innings, when a conference is most likely to matter. A club in a tense game with a runner on in the seventh may spend one to settle a pitcher who has just walked a batter.
A trip to the mound to make a pitching change is free, which means a manager who is out of visits can still make a move by changing pitchers. That has an odd side effect: with visits capped, a pitching change sometimes takes the place of a conference that would have been enough in 2017. It also means that when a coach goes out and the pitcher stays in, the visit has been spent.
The extra-inning allowance matters too. A tied game after nine gives each team one more visit per inning. That connects to the extra-innings runner rule, discussed in the extra-innings runner on second article, because a runner on second base is exactly the situation that used to prompt a sign-change visit. Other ways a schedule can differ from nine innings are covered in the doubleheaders and seven-inning games article.
What the rules do not do
It is worth being careful about what these changes achieved. They addressed idle time, and the most reliable evidence is the league's own: the average game was shorter after 2023, by well over twenty minutes by the league's reporting, and the change was attributed mostly to the pitch clock. The visit cap was a small piece of it. The pickoff limit mattered less for time than for the game's balance, since it shifted advantage toward runners.
What the rules cannot do is address every reason a game gets long: pitching changes, replay reviews and commercial breaks. The league has tackled the number of pitching changes through limits on how many pitchers a team may carry, a subject covered in the roster rules article, and the length of reviews through the challenge system, covered in the replay article. Even the intentional walk, once a four-pitch delay, now takes a signal, as described in the intentional walk article.
Other levels of baseball
These rules apply to major-league games. Minor leagues tested pitch clocks and limits on pickoff throws before they reached the majors, and minor-league rules continue to follow the majors in general terms. Colleges, high schools and youth leagues use their own rules. The NCAA has its own pitch-timing rules, and youth leagues generally have a simpler restriction on how many times a coach may visit a pitcher in an inning. Check the governing body for the level you are watching or coaching; the national organisation's site for Little League is littleleague.org.
Common questions
How many mound visits does a team get? As of the 2025 season, four per nine-inning game, plus one for each extra inning. Check the current rulebook.
Does a pitching change count as a visit? No. If the manager goes to the mound and takes the pitcher out, it is not charged.
What is the pickoff limit? Two disengagements per plate appearance, meaning pickoff throws and step-offs combined. A third that does not retire the runner is a balk.
When does the count reset? When a new batter steps in, and when a runner advances on any play other than a balk.
Why did the league do this? To reduce idle time and to put a cap on a delay tactic that the pitch clock would otherwise have invited.
Do the rules apply in the postseason? Yes, the same rule set applies throughout the regular season and postseason.
