The ball stays live until a rule or an umpire's “Time” makes it dead.

The ruleset used on this page

This page applies the 2026 Official Baseball Rules issued by the Office of the Commissioner of Baseball, with MLB's current ground-rule and replay material. The main provisions are Rules 5.01(b), 5.06(b)(3)–(4), 5.06(c), 5.09(c), 5.12 and 6.01.

The scope is Major League Baseball in the 2026 season. NCAA, NFHS, Little League, independent leagues and international tournaments may adopt another code or supplements. Their appeal procedures, pitching penalties, safety stoppages and boundary awards should not be inferred from this MLB explanation.

A quiet field is not necessarily a dead ball

Rule 5.01(b) supplies the default: once the umpire-in-chief calls “Play,” the ball is alive and stays that way. A routine out, a runner holding a base and a pitcher receiving the return throw may end the immediate action without changing that status.

A dead ball is a legal suspension of play. It can arise automatically under a rule—an uncaught foul ball is the everyday example—or when an umpire calls “Time” under Rule 5.12. A player or manager may request Time, but the request does not protect anyone until an umpire grants it.

Dead does not mean the play has no result

Rule 5.06(c) says that while the ball is dead no player may be put out, no bases may be run and no runs may be scored, except for advances produced by acts that occurred while the ball was live. That is why an umpire can stop action and still award a home run, bases on an overthrow, or placement for interference or obstruction.

The stopping rule controls the outcome. Depending on that rule, the batter may be out or awarded first, runners may return, receive a fixed award, or be placed where the umpire judges they would have reached. “Dead ball” alone never supplies a universal one-base or two-base award.

Common triggers under Rule 5.06(c)

• Pitch touches the batter in a legal batting position: the ball is dead. Rule 5.05(b)(2) decides whether the batter receives first; if the pitch is a strike or the batter made no attempt to avoid an outside pitch, there is no first-base award and runners cannot advance.
• Uncaught foul ball: runners return, and the plate umpire must not put the ball back in play until they have retouched.
• Illegally batted ball: the ball is dead and runners return.
• Balk: the ball becomes dead and the Rule 6.02(a) penalty governs the award, subject to that rule's exception when the live result satisfies the prescribed advances.
• Certain contact with a fair batted ball: a ball that touches a runner or umpire before the conditions in Rule 5.06(c)(6) are met can become dead; the exceptions depend on whether it passed or was deflected by a fielder and whether another infielder still had a play.
• Lodged pitch: if a pitch lodges in the catcher's or umpire's equipment and remains out of play, the ball is dead and Rule 5.06(c)(7) supplies a one-base award.

Out of play is a status and an award question

Rule 5.06(b)(4) separates several events that spectators often group together. A fair ball leaving the field in flight can produce a home-run award. A bounding fair ball that enters the stands, passes through or under a fence, or sticks in specified boundary features gives the batter and runners two bases. A pitch or a pitcher's throw from the rubber that goes directly into dead-ball territory normally produces a one-base award.

A thrown ball entering the stands or another dead area is normally a two-base award. If it was the first play by an infielder, the award is measured from the runners' positions at the time of the pitch; otherwise it is measured from their positions when the throw left the fielder's hand. There is an exception when every runner, including the batter-runner, had already advanced at least one base before that first-play throw.

The same ricochet can be live or dead

MLB's Universal Ground Rules show why the physical boundary must be identified before giving a ruling. A ball resting on certain rotating signage is live, while one lodged there is out of play. A ball rebounding from field-facing protective netting is live; screening behind an out-of-play area is dead even if the ball rebounds onto the field.

Individual ballparks can add approved rules for roofs, walls, railings and other fixed features. “It came back onto the field” is therefore not enough. The relevant question is whether the ball touched or entered an area the Official Rules and that park's ground rules designate as out of play.

Interference does not have one timing rule

• Batter or runner interference: many Rule 6.01(a) offences make the ball dead, create one or more outs and return other runners as the applicable subsection directs.
• Catcher or fielder interference with the batter: under Rule 6.01(c), the umpire lets a following play continue. The offensive manager may accept the play instead of the first-base penalty; if the batter reaches first and every other runner advances at least one base, the play proceeds without applying the interference penalty.
• Plate-umpire interference with a catcher's throw: Rule 5.06(c)(2) disregards the interference if the throw retires the runner. Otherwise the ball is dead and runners may not advance.
• Spectator interference: Rule 6.01(e) makes the ball dead at the moment of interference and calls for judgment placement to nullify it. If the interference clearly prevents a fly-ball catch, the batter is out.
• Accidental contact with an authorized nonparticipant: Rule 6.01(d) can leave the ball live when the person tried to avoid interference; intentional interference makes it dead and brings judgment penalties.

First ask whether a play is being made on that runner

Rule 6.01(h)(1) applies when a play is being made on the obstructed runner, or the batter-runner is obstructed before first base. The ball is immediately dead. The obstructed runner receives at least one base beyond the last legally touched base, and all runners are placed where the umpire judges they would have reached without the obstruction.

Under Rule 6.01(h)(2), if no play is being made on that runner, action continues until no further play is possible. The umpire then calls Time and makes any award needed to nullify the obstruction. If the runner goes beyond the base the umpire would have protected, the runner advances at risk and can be tagged out.

Five events that do not automatically stop play

• Legally caught foul tip: it is a live strike, so runners may advance at their own risk.
• Ordinary ball four: the award of first base does not by itself kill the ball. A runner who advances beyond an awarded base can be put out.
• Fair ball deflected by an infielder and then touching a runner or umpire: Rule 5.06(c)(6) keeps the ball live in the specified deflection situations.
• Uncaught third strike that passes the catcher and strikes an umpire: the Rule 5.06(c)(7) Comment says the ball remains live; an eligible batter-runner can still be retired.
• Detached-equipment award: some deliberate contacts with a thrown glove, cap or mask produce base awards while the ball remains in play under Rule 5.06(b)(3)–(4).

Only the umpire changes the status

Rule 5.12 lists reasons to call Time, including unsafe conditions, an incapacitating accident, a substitution, a conference, examination of the ball and removal of a person from the field. Except for the rule's stated light-failure and incapacitated-runner situations, an umpire is not to call Time while a play is in progress.

After a dead ball, possession alone does not restart play. The pitcher must take a place on the pitcher's plate with the ball, and the plate umpire must call “Play.” Between “Time” and that “Play” call, a tag or throw cannot create an ordinary out.

A dead-ball award does not erase missed bases

Rule 5.06(b)(4)(I) Comment keeps the runner responsible for touching every awarded and intervening base. While the ball is dead, a runner can correct a miss before touching the next base; after touching a base beyond the missed one, Rule 5.09(c)(2) prevents a return during the dead ball.

MLB's appeal itself is a live-ball act: the Rule 5.09(c) Comment says Time is not out when an appeal is made. The defence must wait for “Play,” clearly identify the appeal and act before the next pitch or intervening play. A careless appeal throw that enters dead territory can end the defence's chance to repeat the same appeal.

Some status and placement calls can be corrected

MLB's current replay list includes potential home runs, non-home-run boundary calls, spectator contact at a boundary, specified fair/foul calls, whether a pitch touched a batter, and runner placement following a boundary call. If review changes a call, the replay official may place both clubs as they would have been had the correct call been made.

Replay is not a general appeal of every live-ball, dead-ball or judgment decision. Identify the underlying reviewable category rather than challenging “the ball was dead” in the abstract.

How to rule a disputed sequence

1. Confirm the code: MLB 2026, another governing body's rules, tournament supplements and park ground rules are not interchangeable.
2. Start live: if “Play” has been called, presume the ball remains live.
3. Find the stopping provision: uncaught foul, hit batter, interference, obstruction, out-of-play boundary, lodged ball, balk or an umpire's Time call.
4. Fix the exact moment: some events kill the ball immediately; catcher interference and no-play obstruction are allowed to continue.
5. Apply that provision's outcome: out, return, forced advance, fixed award or judgment placement.
6. Use the correct timing point: time of pitch, time of throw, time of interference and last legally touched base can produce different placements.
7. Preserve touch duties: an award does not excuse a missed base, and an MLB appeal waits for a live ball.
8. Check review and restart: use replay only for a listed category; otherwise wait for the plate umpire's “Play.”

The runner steals on a caught foul tip

Situation: with a runner on first, the batter tips the pitch sharp and direct into the catcher's glove, where it is legally caught. The runner reaches second.

MLB 2026 ruling: the ball remained live. The pitch is a strike, not an uncaught foul ball, and the runner may advance at risk. The decisive fact is the legal catch of the foul tip.

The shortstop's first throw enters the stands

Situation: a runner is on first when the batter grounds to shortstop. The shortstop's first play is a throw that leaves the hand before the batter-runner reaches first and goes into the stands.

MLB 2026 ruling: dead ball; two bases from the time of the pitch under Rule 5.06(b)(4)(G). The original runner is awarded third and the batter-runner second. “Two bases” is not measured from where each runner happened to be when the ball crossed the boundary.

A deflected ground ball strikes the runner

Situation: a fair ground ball passes the first baseman, no other infielder has a play, and it immediately strikes the runner behind that fielder.

MLB 2026 ruling: live ball under the Rule 5.06(c)(6) exception. The runner is not automatically out and fielders may continue the play. The decisive facts are that the ball passed an infielder and no other infielder still had a chance to make a play.

A no-play obstruction is followed by an extra try

Situation: a runner is obstructed while rounding first when no play is being made there. The umpire judges that the runner would have reached second, but the runner tries for third and is tagged out.

MLB 2026 ruling: the ball stays live under Rule 6.01(h)(2). If second is the protected base, the runner's attempt beyond it is at the runner's own risk and the out at third can stand. The obstruction does not provide unlimited protection.

The plate umpire clips the catcher's throw

Situation: on a steal of second, the plate umpire interferes with the catcher's throwing motion, but the throw still retires the runner.

MLB 2026 ruling: the interference is disregarded and the out stands under Rule 5.06(c)(2). If the throw had not retired the runner, the ball would be dead and the runner would return. This is why the umpire waits for the result before enforcing the interference.

Six shortcuts that produce wrong rulings

• “A player asked for Time.” The ball stays live until an umpire grants it.
• “The out ended the play.” Most outs do not make the ball dead.
• “The ball touched an umpire.” Some contact is dead; other contact, including specified deflections and an uncaught third strike striking the umpire, stays live.
• “A walk stops everything.” An ordinary ball four is live.
• “Every overthrow gives two bases from the throw.” A first play by an infielder normally uses time-of-pitch positions.
• “Obstruction always kills the play.” Rule 6.01(h) divides immediate-dead and play-on situations.
