February 19 – The Brooklyn Dodgers signed 19-year-old Roberto Clemente to a one year deal with $5,000, including a $10,000 signing bonus. The Dodgers thus beat out a number of other clubs in the Clemente sweepstakes, as they outspent their cross-river rivals New York Giants and New York Yankees, who had already intention on inking Clemente. Besides, the Dodgers also beat the Milwaukee Braves to the punch, as they offered Clemente more money to sign there. He was assigned immediately to Triple A Montreal Royals. The future Hall of Famer put up decent but not spectacular numbers for them, posting a.257/.286/.372 batting line with ten extra base hits and one stolen base in 155 plate appearances. Unfortunately for the Dodgers, Clemente would never play a game in the organization. At the end of the season, Brooklyn left him exposed to the Rule V Draft, where he was selected by the Pittsburgh Pirates. Clemente would never play another game in the Minor Leagues.
