Outfield Encroachment Restriction (Tuesday/Thursday League Play Only)

  • An Outfield Encroachment Line will be added to the playing field.
    • The restriction requires all outfielders to remain back of a chalk-lined arc.
    • The arc, or encroachment line, will extend from a distance of 175' from home plate beginning at the left field foul line and extending in a corresponding arc across the outfield to a point 175' down the right field foul line.

    • The manager of the team at bat may make an appeal to the umpire regarding the play should the umpire not immediately announce a safe or out call when such an encroachment may have occurred.

(Updated for 2010) Infield Restriction (Tuesday/Thursday League Play Only)

NOTE: This rule will apply in 2010 for all league games played on the Softball and Baseball fields.

  • An Infield Restriction Line will be added to the Baseball Playing Field to be consistent with the depth of the infield on the Softball Field.
    • The infield restriction rule requires all infielders to remain on the dirt (softball field) or in front of the infield restriction line (baseball field) until the batter makes contact with the ball.
  • NEW Infielder in Front of the Restriction Line when Ball is Hit
    • If the ball is hit past the infielder, the batter is safe and cannot be thrown out at first base; all base runners advance at their own risk.
    • If the ball is fielded cleanly in front of the restriction line and infielder travels behind the line, the infielder can throw the batter out at first base; all base runners advance at their own risk.
    • If the ball is NOT fielded cleanly in front of the restriction line and infielder travels behind the line, the batter cannot be thrown out at first base; all base runners advance at their own risk.
    • If the infielder travels behind the restriction line to field a ball, the batter cannot be thrown out at first base; all base runners advance at their own risk.
  • NEW Infielder Behind the Restriction Line when Ball is Hit
    • If an infielder is standing on the grass or behind the restriction line before the batter makes contact with the ball, the infielder cannot throw the batter out at first base; all base runners advance one base safely with additional bases at their own risk, if ball is still in play.
    • Regardless if the ball was fielded cleanly, the umpire will rule the batter and base runners to be safe, if in the judgment of the umpire, the infielder was on the grass or went behind the restriction line prior to the batter making contact with the ball.
    • The manager of the team at bat may make an appeal to the umpire regarding the play should the umpire not immediately announce a safe call when an encroachment may have occurred.
  • A Middle Fielder is considered an infielder unless a Team Manager designates the player as an outfielder.

  • Any inning after the declared final inning or the seventh inning will also be an unlimited run inning.
