A switch-hitting
outfielder who threw
right-handed, Johnston signed with the Pirates in 1959 and spent five full seasons in Pittsburgh's
minor league system before making the Bucs' varsity out of
spring training in . MLB teams were then allowed to carry three extra players on their roster for the first 30 days of the season, and Johnston appeared in 14
games as a
leftfielder,
centerfielder,
pinch hitter and
pinch runner between April 15 and May 11. He logged ten
plate appearances and drew three
bases on balls, but went hitless in seven
at bats. In his only Major League start, as a centerfielder on May 2 against the
St. Louis Cardinals at
Busch Stadium, Johnston came to the plate five times against
southpaws Curt Simmons and
Bobby Shantz; he walked once, reached on an
error, and grounded out three times. His baseball career continued at the Triple-A level through 1966, and he
batted .266 with 59
home runs in 938 minor league games. ==Time with Steelers==
