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.
