In the game against Detroit, Johnson threw 50 pitches over 94 mph, striking out Cecil Fielder (Prince's dad) twice. He ended the game with a 97-mph heater to strike out Mike Heath.
Johnson's masterpiece foreshadowed that the 1990s would be different for the long-suffering franchise. In 1991, the Mariners had their first winning season. Showing the flame-thrower's longevity, Johnson threw a perfect game for the Arizona Diamondbacks 13 years later.
