1986 San Francisco Giants Candlestick Park Stadium Ground Rules Guide
The page outlines the ground rules for baseball games played at Candlestick Park, home of the San Francisco Giants, which first opened on April 12, 1960. The rules primarily address situations that dictate whether a baseball is considered in play or a home run. Rule one specifies that a ball hitting either of the foul poles or the screen attached above the black ring marked on the foul pole results in a home run. If the ball strikes the black ring or below on the foul pole and bounces back into play, it is deemed in play, awarding two bases if it bounces into the stands. The second rule discusses a thrown ball that goes behind the backstop, granting one base to the offensive team if thrown from the rubber.
