His nine-year professional career included 1,073 games in minor league baseball, punctuated by his two trials with the Braves in the closing weeks of the 1962 and 1964 campaigns, when MLB rosters expanded to 40 players. In his debut on September 6, 1962, he doubled in his first MLB at bat against Ernie Broglio of the St. Louis Cardinals.^[1] He had entered the game as a pinch hitter for Braves' catcher Bob Uecker, who later became both a film and television actor and Baseball Hall of Fame play-by-play broadcaster. Blackaby collected only two other hits in the majors, both singles, in 25 at bats over his two brief trials.
