Teach learners to separate possession from consequence. This lesson first tests whether a catch was completed, then shows when the infield fly rule can retire the batter even if nobody catches the ball.

By the end of the lesson, learners should be able to:
A catch and an infield fly answer different questions. One asks what the fielder controlled; the other protects runners from a routine-drop double play.
2026 clarification: after the fielder establishes complete control, opening the glove to make a transfer can show voluntary release. Control in the throwing hand is not required.
The umpire declares it immediately. The batter is out, the ball stays live, and runners may advance at their own risk.
Ask when a catch becomes complete: first glove contact, secure control, transfer, or umpire signal? Use responses to introduce control and voluntary release.
Mime a clean catch and transfer, then a collision-and-drop. Learners identify the fact that changes the ruling.
Display the infield-fly checklist. Change one fact at a time: outs, occupied bases, type of hit, and ordinary effort.
Learners complete all eight situations. Require a ruling and the decisive condition, not a guess from where the ball landed.
Use the three-part outcome strip. Ask learners to explain what the runners may or must do after each result.
For each play, decide the ruling and identify the fact that decides it. These situations use the 2026 MLB Official Baseball Rules.
The outfielder securely controls a fly ball, takes two normal steps, then deliberately opens the glove to transfer the ball. The ball drops before reaching the throwing hand.
Catch or no catch?
An outfielder gloves a fly ball, immediately collides with the wall, falls, and loses the ball. The fielder never demonstrates complete control before the collision.
Catch or no catch?
A pop fly tips off the second baseman’s glove, then the shortstop’s glove, before the first baseman secures it above the ground and voluntarily takes it from the glove.
Can this be a catch?
A fly ball touches an outfielder’s glove, then strikes an offensive runner, and is finally caught by another fielder before reaching the ground.
Does the final possession complete a catch?
A high fair fly descends on shallow outfield grass. The shortstop could catch it with ordinary effort, but the centre fielder moves in and catches it.
Can the umpire correctly call an infield fly?
The batter hits a high fair pop that the shortstop could catch with ordinary effort. The ball drops untouched.
Is the batter automatically out under the infield fly rule?
The batter hits a routine fair pop directly above the second baseman. The fielder intentionally lets it fall untouched.
Does the infield fly rule apply?
Near the first-base line, the umpire declares “Infield fly, if fair.” The untouched ball lands in foul territory before first base and remains foul.
Is the batter out under the infield fly rule?
Look for the exact element of the Catch or Infield Fly definition that controls each result.
The fielder had complete control and then voluntarily and intentionally opened the glove to transfer the ball. Under the clarified 2026 definition, possession in the throwing hand is not required. Rule: Catch definition.
A fielder who drops the ball because of a collision or fall has not made a catch if complete control and voluntary release were not established first. Rule: Catch definition.
The first fielder need not be the one who completes the catch. The ball may be juggled by multiple fielders as long as it does not touch the ground and one fielder eventually establishes the required control and release. Rule: Catch definition.
A ball that first touches a fielder, then touches an offensive player or umpire, is not a catch when another fielder subsequently secures it. Other rules may still govern the ball striking the runner. Rule: Catch definition.
The grass and the identity of the eventual catcher are not controlling. An infielder could catch the qualifying fair fly with ordinary effort, with first and second occupied and fewer than two outs. The batter is out and the ball remains live. Rule: Infield Fly definition.
The rule requires fewer than two outs. With two outs, the dropped fair ball is played normally and the force remains. Rule: Infield Fly definition.
The rule requires runners on first and second, or bases loaded. A runner on first alone is not enough. A different rule concerning an intentionally dropped ball could apply if the fielder first touches the ball; that is not what happened here. Rule: Infield Fly definition.
The declaration near the line was conditional. Because the ball became and remained foul, the infield fly ruling does not retire the batter. Rule: Infield Fly definition.
