Ground Rules

Everyone has to play by the rules. Here are the ones specific to watching games at Rogers Centre.


    • Ball hitting any portion of fence or screen in back of home plate is in play.
    • Pitched ball going into camera booth behind home plate: One base. Thrown ball: Two bases.
    • Ball hitting padding and bouncing over: Two bases.
    • A fairly batted or thrown ball lodging in the padding: Two bases.
    • A fairly batted or thrown ball that goes into the dugout or strikes equipment on the dugout steps is considered in the dugout.
    • Ball hitting padding on outfield fence to foul or seating side of foul line is a dead ball.
  • Guidelines for Movement of Retractable Roofs

    The following operating guidelines will be in effect for the 2011 Baseball Season

  • Roof will be closed when

    • Forecast temperatures will be below 10 degrees C.
    • Winds will be in excess of 64km/hr - 10 min. average wind speed (Design condition)
    • Past experiences have demonstrated that fan comfort may be effected by temperatures between 10 and 15 degrees C - therefore forecasted temperatures at the start and end of game will be factored into the decision
    • Winds above 20 km/hr will also have a cooling effect reducing temperatures below our 10 to15-degree threshold
    • The risk of rain is great ( ie: >75% )
  • Roof will be open when

    Prior to start of the game:

    • Forecast temperatures and environmental conditions permit the safe opening and operation of the roof. Temperatures should be above 15 degrees C with very little chance of precipitation (< 45%). Weather forecasts and radar will be used to determine these ideal conditions

    During the game when:

    • Weather conditions improve. Opening the roof during the game will follow MLB Bulletin D-16 dated March 22, 2011. Factors such as temperature, precipitation and shadows (caused by moving panels ) will be considered before making the final decision to open the roof during a game.
  • Universal Ground Rules

    • Ball on the top step (lip) of the dugout is in play. No equipment is permitted to be left on the top step (lip) of the dugout. If a ball hits equipment left on the top step it is dead.
    • A player is not permitted to step or go into a dugout to make a catch.
    • A player is permitted to reach into a dugout to make a catch. If a player makes a catch outside the dugout and the player's momentum carries him into the dugout, then the catch is allowed and the ball remains alive as long as the player does not fall while in the dugout. See Rule 6.05(a).
    • A batted ball in flight can be caught between or under railings and around screens.
    • A catch may be made on the field tarp.
    • Batted or thrown ball resting on the rotating signage behind home plate or along first base or third base stands is in play.
    • The facings of railings surrounding the dugout and photographers' areas are in play.
    • Any cameras or microphones permanently attached on railings are treated as part of the railings and are in play.
    • Any recessed railings or poles that are in the dugout and photographers' areas are out of play and should be marked with red to mark them out of play.
    • Robotic cameras attached to the facing of the backstop screen are considered part of the screen.
    • A batted ball striking the backstop camera is considered a dead ball.
    • A thrown ball striking the backstop camera is considered in play.
    • A ball striking the guy wires that support the backstop is a dead ball.
