On July 4,1986 At Comiskey Park, with the score 1 – 1 in the bottom of the 8th, Sox OF John Cangelosi leads off with a drive to the right field corner. A fan leans out of the stands and appears to touch the ball as he tumbles onto the field. Anticipating an interference call, Yankee OF Claudell Washington slows down, while the speedy Cangelosi easily reaches third base. The umps don’t see any interference and Cangelosi remains on third, and scores on a sacrifice fly. The Sox win, 2 – 1.
