Johnson was an umpire in the 1993 World Series and the 1990 and 1999 Major League Baseball All-Star Game.

[3] Johnson left a 1982 Oakland-Toronto game with a broken hand after a pitch from Matt Keough hit Willie Upshaw after which the ball then struck Johnson, who was working home plate.

Third base umpire Rich Garcia replaced Johnson behind the plate.

Although the ball glanced off the catcher's mitt of Ron Hassey, it still hit Johnson with enough force to injure him.

[5] In 1994, Johnson and his crew received a police escort following a spring training game.
