Does a baseball touching an MLB umpire always make the ball dead?
No. Under the 2026 Official Baseball Rules, an ordinary pitch or throw that touches an umpire remains live. A fair batted ball can be dead or live depending on whether it touched a fielder or passed an infielder other than the pitcher. Lodged pitches, foul-tip rebounds, an uncaught pitch near home and an umpire hindering a catcher’s throw each have separate rules.
For Baseball viewers who assume that any collision between the ball and an umpire stops the play. · Updated
Ordinary pitch and throw contact stays live
A pitched or thrown ball touching an umpire is generally alive and in play. The rule has specific exceptions and special branches, so the ordinary-contact statement does not decide what happens when a ball lodges out of play or when another interference provision applies.
A lodged pitch and a foul-tip rebound have their own outcomes
If a pitch lodges in the catcher’s mask or paraphernalia, or in or against the umpire’s body, mask or paraphernalia, and remains out of play, the rules award runners one base. On strike three or ball four, the batter is entitled to first and runners advance one base. On another pitch when the count has fewer than three balls, runners advance one base under the stated provision.
A foul tip that hits the umpire and is caught by a fielder on the rebound is dead; the batter cannot be called out on that rebound catch. A third strike that is not a foul tip and hits the umpire stays live. If that ball rebounds and is caught before touching the ground, the catch itself does not retire the batter, who may still be retired at first or tagged.
For a fair batted ball, check prior contact and passage
A fair ball that hits an umpire on fair territory makes the ball dead only if both conditions hold at that contact: no fielder has touched the ball, and it has not passed an infielder other than the pitcher. In that case, the batter-runner is awarded first; other runners advance only if forced, and awarded bases still have to be touched.
It remains live if it has already touched any fielder, including the pitcher, or has passed an infielder other than the pitcher before it contacts the umpire. Merely bounding over or past the pitcher does not count as passing a non-pitcher infielder.
A separate Comment says that if a fair batted ball is deflected by a fielder in fair territory, then hits a runner or umpire while still in flight and is caught by an infielder, the catch is not legal; the ball remains in play.
A hindrance to the catcher’s throw is umpire interference
When the plate umpire hinders the catcher’s throw while the catcher is trying to prevent a steal or retire a runner on a pickoff, the ball is dead and runners may not advance if catcher-throw interference applies. If the throw retires the runner, disregard the interference and do not deaden the successful throw. The Comment also covers an umpire hindering the catcher’s return throw to the pitcher.
A near-home uncaught pitch is another narrow case
If an uncaught pitch remains near home and is inadvertently deflected by the batter or umpire, the ball is dead and runners return to the bases occupied at the time of the pitch. If it was strike three, the batter is out. Separately, a pitch that deflects from the catcher or umpire and then touches the batter-runner is not interference unless the umpire judges that the batter-runner clearly hindered the catcher’s attempt to field it.
Separate contacts, separate branches
In a fictional play, an ordinary throw from fielder Luis clips an umpire without lodging or creating another interference situation; the ball remains live. In another stipulated play, an untouched fair grounder passes only the pitcher and hits the infield umpire before reaching another infielder; the ball is dead, the batter-runner is awarded first and forced runners advance. If the same grounder first touches the pitcher, or passes a non-pitcher infielder before hitting the umpire, the ball remains live. In a separate steal attempt, the plate umpire hinders catcher Ren’s throw to second: runners do not advance, unless that throw retires the runner, in which case the interference is disregarded. An uncaught pitch inadvertently deflected by the batter or umpire near home follows the separate dead-ball and time-of-pitch return rule.

Does a throw that hits an umpire stop play?
Ordinarily no. A pitched or thrown ball touching an umpire remains live unless a specific rule, such as a lodged ball out of play, applies.
What if the umpire hinders a catcher’s throw to second?
Runners may not advance under the umpire-interference rule. If the throw retires the runner, the interference is disregarded.
Can a rebound catch retire a batter on a third strike that hits the umpire?
No. If the third strike was not a foul tip, the ball remains live, but catching the rebound before it hits the ground does not itself retire the batter. The batter may still be retired at first or tagged.
