<p>
In baseball, <b>interference</b> occurs in situations in which a person illegally changes the course of play from what is expected. Interference might be committed by players on the offense, players not currently in the game, catchers, umpires, or spectators. Each type of interference is covered differently by the rules.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup>
</p>

<div class="mw-heading mw-heading2"><h2 id="Offensive_interference">Offensive interference</h2></div>

<p>The most common incidence of interference occurs when a member of the offensive team physically hinders the defensive team, decreasing its chances to make an out or increasing the chance that a baserunner will advance. Whenever this <i>offensive interference</i> occurs, the <a href="Dead_ball_(baseball)" class="mw-redirect" title="Dead ball (baseball)">ball becomes dead</a>. If the interference was committed by a <a href="Batter_(baseball)" class="mw-redirect" title="Batter (baseball)">batter</a> or a <a href="Baserunner" class="mw-redirect" title="Baserunner">baserunner</a>, that player is called <a href="Out_(baseball)" title="Out (baseball)">out</a> and all other runners must return to the bases they occupied at the time of the interference. If interference is committed by a runner with the obvious intent of preventing a <a href="Double_play" title="Double play">double play</a>, the batter-runner will be called out in addition to the runner who committed the interference. If interference is committed by the <a href="Batter-runner" class="mw-redirect" title="Batter-runner">batter-runner</a> before they reach first base with the possible intent of preventing a double play, the runner closest to scoring is called out in addition to the batter-runner. If interference is committed by a retired runner or by some other member of the offensive team, the runner who is most likely to have been put out will be called out.
</p><p>Under <a href="Little_League" class="mw-redirect" title="Little League">Little League</a> (LL), high school (<a href="National_Federation_of_State_High_School_Associations" title="National Federation of State High School Associations">NFHS</a>) and college (<a href="NCAA" class="mw-redirect" title="NCAA">NCAA</a>) rules, if interference is committed by a runner with the effect of preventing a likely double play, regardless of their intent, the batter-runner will be called out in addition to the runner who committed the interference.
</p><p>Also under NFHS rules only, all runners are required to attempt to avoid collisions. If a runner fails to do so, they are guilty of <b>malicious contact</b>, which is one kind of offensive interference. Malicious contact carries the additional penalty of ejection from the game. In contrast, in professional and higher amateur baseball, violent collisions can occur without any interference (or obstruction), especially when a fielder is receiving a thrown ball near a base where a runner is trying to reach. Any collision that occurs in this situation is not interference, because the fielder's action is in regard to a thrown ball. As long as such a runner's actions are related to their attempt to reach the base, they cannot be called for interference. The most common case of this is when a runner is attempting to score and the catcher has control of the ball. If the catcher is in the path between <a href="Third_base" class="mw-redirect" title="Third base">third base</a> and <a href="Home_plate" class="mw-redirect" title="Home plate">home plate</a>, the baserunner may strike the catcher with their body in an attempt to dislodge the ball from the catcher's hand and then reach home plate. This is usually attempted only when the play is close. When the catcher is set up and ready, the runner has little chance of knocking the ball away. Any such attempt presents a significant chance of injury to the baserunner, which has prompted the malicious contact rule to be used more often.
In addition to the general subjective definition of offensive interference, it is also interference by specific rule when:<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup>
</p>
<ul><li>The bat hits the ball a second time in fair territory, such as while the bat is being dropped;</li>
<li>A batter or runner intentionally deflects the course of a batted ball in any manner;</li>
<li>A member of the offensive team stands near a base to impersonate a baserunner or to otherwise confuse or hinder the defense;</li>
<li>A coach physically assists a runner in returning to or leaving first or third base;</li>
<li>A batter, while running to first base, runs outside the three-foot running lane and interferes with the fielder taking a throw at first base;</li>
<li>A runner makes contact with a batted ball that did not go through or by a fielder, unless no infielder had a chance to immediately field the ball (in this instance, the runner is out, the batter is credited with a base hit, and no other runner advances unless forced to advance one base);</li>
<li>A runner makes contact with a fielder attempting to field a batted ball, except the batter with the catcher in the immediate vicinity of home plate immediately after the ball was batted; or</li>
<li>A member of the offensive team intentionally touches a thrown ball, or intentionally hinders a fielder attempting to make a throw.</li>
<li>The batter physically hinders the catcher's opportunity to throw out a baserunner while standing outside of the batter's box.</li></ul>
<p>There are some exceptions to the penalty for offensive interference.
</p>
<ul><li>If there are fewer than two outs and a runner is trying to score, and the batter interferes with the tag attempt at home plate, then the runner is out for the batter's interference, while the batter is not out. If there are two outs in this situation, the normal interference penalty applies: the batter is out and the run does not score.</li>
<li>If a runner's interference is caused by being positioned at a legally occupied base and the fielder is trying to make a play on a batted ball in the vicinity of the base, interference is not called.</li></ul>
<div class="mw-heading mw-heading3"><h3 id="Verbal_interference">Verbal interference</h3></div>
<p>At some levels of play, verbal as well as physical hindrance can be called for interference. For example, if a runner or other member of the offense calls out "foul" on a fair ball or "mine" on a fly ball, they may cause the defense to react differently from how they otherwise would have, resulting in an interference call.
Some professional leagues do not have a distinction for verbal interference or obstruction and leave it as umpire judgement. The NPB in Japan, for example, verbal interference is illegal and runners will be called out on any spoken word meant to confuse a fielder or fielders during a play. In Major League Baseball, it is left as umpire judgement.

<p>On October 15, 1969, in Game 4 of the <a href="1969_World_Series" title="1969 World Series">1969 World Series</a> between the <a href="New_York_Mets" title="New York Mets">New York Mets</a> and <a href="Baltimore_Orioles" title="Baltimore Orioles">Baltimore Orioles</a>, Mets <a href="Pinch_hitter" title="Pinch hitter">pinch hitter</a> <a href="J._C._Martin_(baseball)" title="J.

The Orioles protested vehemently, but although replays showed Martin ran inside the first base line, umpires ruled the play valid and no interference was called. The win gave the "Miracle Mets" a 3–1 lead in the series, and they closed out their championship season with a win the next day.
</p><p>An alleged offensive interference occurred in the third game of the <a href="1975_World_Series" title="1975 World Series">1975 World Series</a>. With a runner on first, Cincinnati Reds player <a href="Ed_Armbrister" title="Ed Armbrister">Ed Armbrister</a> laid down a sacrifice bunt. Red Sox catcher <a href="Carlton_Fisk" title="Carlton Fisk">Carlton Fisk</a> attempted to field the ball and throw to second base and get the lead runner out. However, Armbrister did not immediately run to first base but instead stood essentially still in the vicinity of home plate, forcing Fisk to jump into him in order to make the throw. As a result, Fisk's throw went into center field, and the Reds ended up with runners on first and third with no outs. The Red Sox protested, saying that Armbrister interfered, but home plate umpire <a href="Larry_Barnett" title="Larry Barnett">Larry Barnett</a> refused to change the call. The rules at the time did not mention a batter-runner/catcher collision, but the official interpretation issued to the umpires did; there is no violation on such unintentional contact.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> The Red Sox lost the game, and the series.

<p>It is <i>umpire's interference</i> when the <a href="Umpire_(baseball)" title="Umpire (baseball)">umpire</a> hinders a catcher's attempt to throw anywhere. In this case, if the catcher's direct throw retires a runner the play stands. If not, the ball is dead and all runners must return to the bases they had most recently touched before the catcher's throw.
</p><p>It is also umpire's interference when an umpire is struck by a fair batted ball before it touches a fielder including the <a href="Pitcher" title="Pitcher">pitcher</a> or passes near an infielder other than the pitcher. This can occur either because an umpire is inside the diamond or because the ball crosses 1st or 3rd base in fair territory then hooks or slices foul into the umpire positioned just outside the line behind the bag. In this case, the ball is dead, the batter is awarded first base, and all other runners advance only if forced. A common example is when a batter hits a fair ball down the first base line so hard that the first base umpire can't avoid it. Even though the hit would have surely been a bases-clearing double or triple without the interference, it is only a single and runners advance no more than one base. This happened in the <a href="1989_Major_League_Baseball_All-Star_Game" title="1989 Major League Baseball All-Star Game">1989 All-Star Game</a> when the <a href="Pittsburgh_Pirates" title="Pittsburgh Pirates">Pittsburgh Pirates</a>' <a href="Bobby_Bonilla" title="Bobby Bonilla">Bobby Bonilla</a> led off the 9th with a scorching grounder that would have been an easy double, but it hit first base umpire <a href="Bob_Engel" title="Bob Engel">Bob Engel</a> in the legs as he tried to jump out of the way. Instead of being in scoring position down 5–3, Bonilla was forced out at 2nd the next play and the game ended on a double play.
</p>
<div class="mw-heading mw-heading2"><h2 id="Catcher's_interference">Catcher's interference</h2></div>

<p><i>Catcher's interference</i> is called when the <a href="Catcher" title="Catcher">catcher</a> physically hinders the batter's legal swing at a pitched ball. This usually occurs when a catcher <a href="Squatting_position" title="Squatting position">squats</a> too close to home plate, so that the batter's bat hits the catcher's mitt as the batter swings. This is most likely to happen on attempted steals where the catcher is anxious to catch the ball as soon as possible and may move their entire body or mitt forward a bit. It also more commonly happens to hitters who let pitches get deeper and take later swings,<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> such as <a href="Jacoby_Ellsbury" title="Jacoby Ellsbury">Jacoby Ellsbury</a>, who holds the record for the most times interfered with by a catcher in both a single season and his career.<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup>
</p><p>In this case, play continues until the play ends and the umpire calls time. The penalty is that the batter is awarded first base, any runner attempting to <a href="Stolen_base" title="Stolen base">steal</a> is awarded that base, and all other runners advance only if forced. Additionally, the catcher is charged with an <a href="Error_(baseball)" class="mw-redirect" title="Error (baseball)">error</a> and the batter is not charged with an at-bat. However, if the playing result is more advantageous than the penalty, the offense may elect to ignore the infraction (e.g., if the batter-runner reaches first safely and all other runners advance at least one base, catcher's interference is ignored by rule, or if a run scores even though the play resulted in an out the offense may elect to take the play versus the penalty by appealing to the calling umpire).
</p><p>Under high school (NFHS) rules only, catcher's interference is instead called <i>catcher's obstruction</i>.<sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup>
</p>
<div class="mw-heading mw-heading2"><h2 id="Spectator_interference">Spectator interference</h2></div>
<p>When a spectator or other person not associated with one of the teams (including such staff as bat and ball boys/girls) alters play in progress, it is <i>spectator interference</i>, colloquially called <i>fan interference</i>. It is worth noting that the latter is also (incorrectly) used to refer to fan obstruction – for instance a spectator running onto the field and tackling a baserunner.<sup id="cite_ref-8" class="reference"><a href="#cite_note-8"><span class="cite-bracket">[</span>8<span class="cite-bracket">]</span></a></sup> The ball becomes dead, and the umpire will award any bases or charge any outs that, in their judgment, would have occurred without the interference.<sup id="cite_ref-9" class="reference"><a href="#cite_note-9"><span class="cite-bracket">[</span>9<span class="cite-bracket">]</span></a></sup>
</p><p>Such interference often occurs when a spectator in the first row of seats reaches onto the field to attempt to grab a fair or foul fly ball. If the umpire judges that the fielder could have caught the ball over the field (i.e., the ball would have not crossed over the plane of the wall), they will rule the batter out on spectator interference. Spectators who commit interference are typically ejected from the stadium.
</p><p>However, spectators <i>are</i> allowed to touch and/or catch a ball that is still in play once the ball has broken the plane of the spectators' side of the wall. Spectators may even use a certain level of non-violent force (for example, they may attempt to dislodge a ball out of a defender's glove) provided they do not themselves cross the plane in their efforts. The area where both fielders and spectators are legally allowed to touch the ball is colloquially called <i>no man's land</i>.
</p><p>Umpires typically grab their wrist above their head to signal that spectator interference has occurred.

<div class="mw-heading mw-heading2"><h2 id="Common_misconceptions">Common misconceptions</h2></div>
<p>When a fielder hinders a baserunner, the situation is called <a href="Obstruction_(baseball)" title="Obstruction (baseball)">obstruction</a>, not interference. Baseball commentators often mistakenly refer to obstruction as interference.
</p><p>Not all physical contact in baseball is interference. Accidental contact that has little or no effect on play is usually ignored; physical contact must result in an advantageous situation for the offense to be considered offensive interference. Nor must physical contact occur for interference to be called; a runner may interfere with a fielder simply by hindering the fielder's ability to attempt to make a play on a batted ball.
</p><p>If a baserunner is hit by a fair batted ball while standing on a base, the runner is out, unless the ball has already passed an infielder or the <a href="Infield_fly" class="mw-redirect" title="Infield fly">infield fly</a> rule has been declared.

</p><p>However, being in contact with a base may protect a baserunner from being called out for interference in the case of a fielder attempting to field a batted ball.
