Apparently there were two Randy Johnsons that played in the Major Leagues in the 1980’s. The first one to crack an MLB roster was Randall Glenn Johnson, who played a total of 204 games with the Atlanta Braves from 1982-1984.
The second had a bit more success, as Randall David Johnson won 303 games with six teams, including the dirty, awful Yankees, striking out 4875 total batters.
How we know they’re different people:
The Randy Johnson who achieved utility player status with the Atlanta Braves is listed at 6 feet 1 inch tall. The Randy Johnson who broke in with the Expos and achieved fame and fortune with the Seattle Mariners is 6 feet 10 inches tall. This made him the tallest Major Leaguer in history until Jon Rauch took his talents to the South Side of Chicago. You can tell how tall he is based on the photograph on his 1991 Topps card. The photographer was obviously much shorter, or maybe just creepy.
How we’re not sure they’re different people because we’ve never seen them in the same room together:
Both are from California and played the latter parts of their careers in Phoenix (Randall Glenn with the old Phoenix Firebirds of the PCL, and Randall David with the Arizona Diamondbacks, in both the purple and post-purple eras). They also both had mustaches. Coincidence? I think not.
Confusion alleviated? No big deal.
