Denkinger was a good umpire.  He worked four World Series, serving as crew chief in two.  The affable Iowan umpired the All-Star Game in 1971, 1976 and 1987, calling balls and strikes for the last game.  He officiated in six American League Championship Series and two Division Series.  Denkinger was behind the plate for the 1978 Yankees-Red Sox tiebreaker --  the famous Bucky Dent home run game.
