A right-handed batter and thrower, Johnson stood 6 feet 2 inches (1.88 m) tall and weighed 215 pounds (98 kg).On perhaps the best day in his career, on June 19, 1977, against the A's, Johnson sang the National Anthem before the game, and followed up with two homers, the only White Sox hits on the day, as the Sox won 2-1.
