Infield Fly Rule (Majors only)

Runners on 1st and 2nd or bases loaded, less than 2 outs—a fly ball (not a line drive) that can be caught by an infielder with ORDINARY effort (umpire’s discretion)—batter is out. Runners may advance at their own risk. There is no infield fly rule in Minors.

No “Must Slide” Rule

Runner must either AVOID the fielder with the ball or SLIDE. A head-first slide is an automatic out (unless returning to a base). The fielder covering a base may not obstruct the runner or block the base unless he is in possession of the ball.


All catchers MUST wear a cup. Any player warming up the pitcher must be properly equipped with a full mask and helmet, catcher’s mitt and protective cup. COACHES MAY NOT WARM UP PITCHERS AT ANY TIME.

Minimum Play Requirements

Continuous batting order is used—all players, whether playing in the field or not, bat in their order. All eligible players should play a minimum of 4 full innings in the field. In the minors, even and balanced playing time for all players is required. (i.e. the same player should not sit 2 innings every game). Also, every player should have many opportunities to play infield.

Curve Balls

The throwing of curve balls is strongly discouraged.

Umpire Respect by Coaches

No coach may argue or question a judgment call. If reported and confirmed, coach will be suspended one game. If same coach repeats, coach may be suspended for remainder of season.

Equipment Inspection

Each team’s coaches should inspect its equipment prior to each game. At a minimum, inspection should confirm that all bats are LL approved, catcher’s gear is in working order, and helmets are safe.

Dropped Third Strike (Minors only)

In Minors only, the batter is out on called or swinging third strike whether or not the catcher catches the ball. For majors, please see details in LLI Rulebook regarding a dropped 3rd strike.

Only 8 players available: (a) Regular Season

For defense, the short team will “borrow” the player who batted last for the other team during the other team’s last at bat, and the “borrowed” player should play left or right field. If the short team is the home team, then it should use the last batter in the other team’s batting order in the first inning. For offense, the short team’s lineup will consist of the 8 players available. In Minors only, if a team knows in advance that it will have fewer than 9 players, the team may “borrow” another player(s) from another team, using reasonable discretion in choosing the player(s) based upon the ability of the team’s missing players. (b) Playoffs: For defense, short team should follow regular season rule. For offense, the short team must take an automatic out for the 9th spot in the batting order. The YLL VP and President should be consulted when a team has fewer than 8 players in the playoffs.
