Not only did Al Dark end up with a nifty career that included several top 10 MVP finishes and All-Star Game appearances, he was the first Brave to win the Rookie of the Year award. He played a major role during the 1948 World Series season. He looked primed to hold the SS position in Boston for a long time.
Of course, he didn’t. It’s hard to figure why he was traded to the Giants after the 1949 season. It goes to show that the Braves have always had a tendency to make bad trades.
