Baseball Umpire Signals Explained: Safe, Out, Strike, Fair, and More

Baseball umpires use a standardized set of hand and arm gestures — safe, out, strike, fair, foul, home run, infield fly, time, and ball-strike counts — so every call is visible to players, coaches, and fans regardless of crowd noise. These signals are taught the same way at the MLB, college, high school, and youth levels, which is why a call at a Little League field looks identical to one at a major-league park. Below is a complete breakdown of each signal, what it looks like, and when an umpire uses it.

The Core Baseball Umpire Signals (Quick Reference Table)

Use this table as a cheat sheet for the signals you will see most often during a game.

Signal	Gesture	Meaning
Safe	Both arms extended forward, then swept outward parallel to the ground, palms down	A runner has reached the base before being tagged or forced out
Out	Clenched right fist snapped downward in a sharp “hammer” motion	A batter or runner is retired; often paired with a loud verbal “out!”
Strike	Clenched right fist punched to the side (“pounding the door”)	A pitch is called a strike, whether looking or swinging
Ball	No hand signal — verbal call only	A pitch is outside the strike zone and not swung at
Foul	Both arms raised straight up while calling “foul” loudly	The batted ball lands or is touched outside fair territory
Fair	Right or left arm pointed directly into fair territory	The batted ball is ruled in play within the foul lines
Home Run	Right arm raised skyward with the index finger twirling in a circle	A batted ball clears the outfield fence in fair territory
Infield Fly	Right arm raised straight overhead, fist or index finger extended	A fly ball meets infield fly rule criteria; the batter is automatically out
Time	Both arms raised while calling “time” loudly	Play is stopped and the ball is dead
Count (balls/strikes)	Fingers displayed on both hands — left hand for balls, right hand for strikes	Communicates the current count to both dugouts

Safe and Out Signals

The safe and out calls are the most recognizable gestures in the sport. For a safe call, the umpire extends both arms straight out in front of the body, then sweeps them outward to the sides with palms facing down — the classic “safe” motion fans imitate in the stands. For an out, the umpire clenches the right fist and delivers a quick, sharp punching motion downward, sometimes called the “hammer.” Umpires are given latitude for personal flair on close plays, as long as the gesture stays clear and doesn’t distract from tracking continuing action on the field. This pairing works the same way across most bat-and-ball and invasion sports; if you compare it to the signals used in other leagues, see our full breakdown of referee hand signals by sport.

Strike and Ball Signals

For a strike, the plate umpire throws a clenched right fist to the side in a short, sharp motion, often verbalized loudly on called third strikes so both dugouts hear it clearly. On swinging strikes, many umpires give only the physical signal since the batter’s own swing already communicates the outcome. A ball, by contrast, has no hand signal at all — the umpire simply says “ball” from the crouched stance and rises. One common coaching point among umpires is to never point toward first base on ball four; the verbal call is the entire mechanic, and pointing can be mistaken for a different signal mid-play.

Fair Ball and Foul Ball Signals

A fair ball is signaled by pointing the arm directly into fair territory, and umpires are trained never to verbalize “fair ball” — silence combined with the point is the correct mechanic, since a spoken “fair” could be confused with other calls. On close plays near the foul line, umpires will stab the arm toward fair territory several times for emphasis. A foul ball, on the other hand, is always both signaled and shouted: both arms go straight up while the umpire calls “foul” loudly enough for players in both dugouts to hear. Once a foul ball is verbalized, the call cannot be reversed, which is why umpires wait a beat on close calls near the line before committing.

Home Run and Foul Tip Signals

When a batted ball clears the outfield fence in fair territory, the umpire points the right arm skyward and twirls the index finger in a small circular motion — the universal home run signal, most useful on close calls down the foul lines or near the top of the wall. A foul tip is a more subtle signal: the umpire extends the left arm, brushes the back of the left hand with the right hand, and then follows with the strike signal. Umpires are trained never to say “foul tip” out loud, since it sounds too similar to a plain “foul” call and could confuse the defense on a play that is actually still live.

The Infield Fly Signal

The infield fly rule exists to prevent infielders from intentionally dropping an easy pop-up to turn a cheap double play with runners on base. When the rule’s conditions are met — a fair fly ball, fewer than two outs, and runners on first and second (or bases loaded) — the umpire raises the right arm straight overhead, often with a closed fist or extended finger, and calls “infield fly, batter’s out!” as loudly as possible. If the ball could land in either fair or foul territory, the umpire adds “if fair” to the call so the ruling is only in effect if the ball actually settles fair. Other umpires on the crew typically echo the signal so it’s visible to both benches at once, since misreading this call can change a team’s entire baserunning strategy mid-play.

Time and Count Signals

To stop play, an umpire raises both arms and calls “time” loudly and sharply — this creates a dead-ball situation and must be heard by every player on the field before action resumes. To restart play after any dead-ball stoppage, the umpire points at the pitcher with a stabbing motion of the right arm and calls “play.” Between pitches, the plate umpire keeps both benches informed of the count by holding up fingers on both hands — the left hand for balls, the right hand for strikes — while announcing the count aloud (for example, “two and one,” never shortened to ambiguous phrasing). These count and time signals are baseball’s version of the administrative gestures every sport relies on; basketball referees use a comparable system of possession and clock signals, detailed in our guide to basketball referee signals, and soccer officials use their own distinct set covered in our soccer referee signals explainer.

Why These Signals Matter

Standardized umpire signals exist because baseball is played in front of crowds that can drown out a spoken call, and because plays often happen far from where fans, broadcasters, or even other umpires are looking. A clear, consistent gesture lets a play be understood instantly from any seat in the ballpark or any camera angle in a broadcast. This is also why the signals are taught identically across levels — a call in a major-league park under MLB rules uses the exact same mechanics as a call at a high school or Little League field, so players moving up through the sport never have to relearn the visual language of the game.
