second base

Second base can refer to:

• Second baseman in baseball
• One of a number of baseball metaphors for sex

In baseball and softball, second baseman is a fielding position in the infield, between third and first base. The second baseman often possesses quick hands and feet, needs the ability to get rid of the ball quickly, and must be able to make the pivot on a double play. In addition, second basemen are usually right-handed; only four left-handed throwing players have ever played second base since 1950. In the numbering system used to record defensive plays, the second baseman is assigned the number 4.
