Second baseman

In baseball and softball, second baseman, abbreviated 2B, is a fielding position in the infield, between second 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 in Major League Baseball since 1950. In the numbering system used to record defensive plays, the second baseman is assigned the number 4. Good second basemen need to have very good range since they have to field balls closer to the first baseman who is often holding runners on, or moving towards the base to cover. On a batted ball to right field, the second baseman goes out towards the ball for the relay. Due to these requirements, second base is sometimes a primarily defensive position in the modern game, but there are hitting stars as well. The second baseman catches line drives or pop flies hit near him, and fields ground balls hit near him and then throws the ball to a base to force out a runner. In this case, if the runner is to be forced out at second base then that base is covered by the shortstop.

With a runner on first base, on a ground ball to the shortstop or third baseman the second baseman will cover second base to force out the runner coming from first. Moreover, if there are fewer than two outs he will attempt to turn the double play: that is, he will receive the throw from the other player with his foot on second base (to force out the runner coming from first base), and in one motion pivot toward first base and throw the ball there (to force out the batter before he gets there).

If a runner on first base attempts to steal second base, or if the pitcher attempts to pick off a runner already at second base, then either the second baseman or the shortstop will cover second base.
