Walter James Vincent "Rabbit" Maranville was an American professional baseball shortstop, second baseman and manager. He played in Major League Baseball (MLB) for the Boston Braves, Pittsburgh Pirates, Chicago Cubs, Brooklyn Robins, and St. Louis Cardinals between 1912 and 1934. At the time of his retirement in 1935, he had played in a record 23 seasons in the National League, a mark which was not broken until 1986 by Pete Rose.

Shortstop, abbreviated SS, is the baseball or softball fielding position between second and third base, which is considered to be among the most demanding defensive positions. Historically, the position was assigned to defensive specialists who were typically poor at batting and were often placed at the bottom of the batting order. Today, shortstops are often able to hit well and many are placed at the top of the lineup. In the numbering system used by scorers to record defensive plays, the shortstop is assigned the number 6.
