Brothers Duane and Glen Kuiper might be broadcasters for opposing San Francisco Bay area major-league teams, but there’s no sibling rivalry between them and are able to keep it friendly away from the diamond.
Duane was a former major-league player from 1974 to 1985, ending his career with the San Francisco Giants. Now he is one of the broadcasters for the Giants.
Glen had a brief minor-league career in 1985-1986 and is currently a broadcaster with the Oakland A’s.
