Mound visits and pitching changes.

How umpires handle a visit

1. Decide whether the action is a charged mound visit, a pitching change, or an allowed exception such as an injury check.
2. If it is a charged visit, count it against the team's game allotment where that rule applies.
3. Check whether the same pitcher has already received a manager or coach visit in the same inning.
4. If the visit requires removal, make sure the replacement pitcher enters legally and satisfies any minimum-batter rule.
5. Resume play only after the substitution, warmup allowance, and official lineup changes are clear.

A mound visit is a defensive conference

A mound visit usually means a manager, coach, catcher, or another defensive player goes to the mound to talk with the pitcher. The purpose can be strategy, pitch selection, signs, tempo, or calming the pitcher down. In MLB, player visits count as mound visits unless an exception applies.

The team has a game allotment

Under current MLB pace-of-play rules, mound visits without a pitching change are limited to four per team per nine innings. If a defensive team has no visits remaining at the end of the eighth inning, it receives one additional visit for the ninth. Extra innings also allow additional visits under MLB's pace-of-play framework.

A second trip can force removal

The older trip rule still matters. If a manager or coach visits the same pitcher twice in the same inning, the pitcher generally must be removed from the game. This is separate from the team's total visit allotment: a team can still have visits left and nevertheless be required to change pitchers because it visited the same pitcher twice in that inning.

A change is not just a normal visit

When the manager comes out to replace the pitcher, the visit is treated as a pitching change rather than an ordinary mound conference. The new pitcher must be reported, gets the allowed warmup pitches, and becomes the legal pitcher once the substitution is made. In professional baseball, that pitcher normally must face at least three batters or finish the half-inning before being removed, unless an injury or other rulebook exception applies.

Not every trip is charged

Rules commonly exclude visits for injuries, equipment or weather-related issues, and certain administrative situations such as after an offensive substitution. MLB also allows umpire-supervised conferences in limited cases where pitcher and catcher signals were crossed up. The exact exceptions depend on the competition, so youth, school, tournament, and local-league games should be checked against their own rulebook.

Running out changes the options

Once a team has exhausted its mound visits, a manager or coach cannot simply use another strategy conference. In MLB, a manager or coach who goes to the mound after the allotment is gone generally must make a pitching change, subject to rules that may prevent an immediate removal such as the three-batter minimum. A player who tries to hold an unauthorized conference can be ordered back to position and may face discipline if they delay play.

Misunderstandings to avoid

• "The catcher can go out whenever he wants" is wrong in MLB. Catcher visits are usually counted unless an exception applies.
• "A pitching change uses up a normal visit" is incomplete. Visit limits usually apply to mound visits without a pitching change.
• "Only the total visit limit matters" is wrong. The same-inning trip rule can force removal even before the team allotment is exhausted.
• "The new pitcher can be removed immediately" is usually wrong in MLB because of the three-batter minimum, unless the inning ends or an exception applies.
• "Every league uses the MLB number" is wrong. Amateur and youth baseball often use different visit limits and pitcher-removal rules.

How the ruling changes

• Coach visits once, leaves, then returns to the same pitcher in the same inning: the second trip generally requires a pitching change.
• Catcher walks out to review signs: in MLB, that normally counts as a mound visit unless an exception applies.
• Trainer and manager check an apparent injury: the umpire can treat the trip differently from a strategy visit if the rulebook exception is met.
• Manager is out of visits and crosses the foul line to confer: the team may be required to change pitchers if a legal change is available.
